[00115] Referring initially to Fig. 1 , an exemplary embodiment of an expandable tubular assembly 10 includes a first expandable tubular member 12 coupled to a second expandable tubular member 14. In several exemplary embodiments, the ends of the first and second expandable tubular members, 12 and 14, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first expandable tubular member 12 has a plastic yield point YP1 f and the second expandable tubular member 14 has a plastic yield point YP2. In an exemplary embodiment, the expandable tubular assembly 10 is positioned within a preexisting structure such as, for example, a wellbore 16 that traverses a subterranean formation 18.
[00116] As illustrated in Fig. 2, an expansion device 20 may then be positioned within the second expandable tubular member 14. In several exemplary embodiments, the expansion device 20 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services,
Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 20 is positioned within the second expandable tubular member 14 before, during, or after the placement of the expandable tubular assembly 10 within the preexisting structure 16.
[00117] As illustrated in Fig. 3, the expansion device 20 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member
14 to form a bell-shaped section.
[00118] As illustrated in Fig. 4, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 14 and at least a portion of the first expandable tubular member 12.
[00119] In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 12 and 14, are radially expanded into intimate contact with the interior surface of the preexisting structure 16.
[00120] In an exemplary embodiment, as illustrated in Fig. 5, the plastic yield point YP-, is greater than the plastic yield point YP2. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand the second expandable tubular member 14 is less than the amount of power and/or energy required to radially expand the first expandable tubular member 12.
[00121] In an exemplary embodiment, as illustrated in Fig. 6, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility DPE and a yield strength YSPE prior to radial expansion and plastic deformation, and a ductility DAE and a yield strength YSAE after radial expansion and plastic deformation. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YSPE. In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YSAEis greater than YSPE, the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process. [00122] In an exemplary embodiment, as illustrated in Fig. 7, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 10 described above with reference to Figs. 1-4, at least a portion of the second expandable tubular member 14 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 12. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 14. Another expandable tubular assembly 22 that includes a first expandable tubular member 24 and a second expandable tubular member 26 may then be positioned in overlapping relation to the first expandable tubular assembly 10 and radially expanded and plastically deformed using the methods described above with reference to Figs. 1-4. Furthermore, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 20, in an exemplary embodiment, at least a portion of the second expandable tubular member 26 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 24. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 26. Furthermore, in this manner, a mono- diameter tubular assembly is formed that defines an internal passage 28 having a substantially constant cross-sectional area and/or inside diameter.
[00123] Referring to Fig. 8, an exemplary embodiment of an expandable tubular assembly 100 includes a first expandable tubular member 102 coupled to a tubular coupling 104. The tubular coupling 104 is coupled to a tubular coupling 106. The tubular coupling 106 is coupled to a second expandable tubular member 108. In several exemplary embodiments, the tubular couplings, 104 and 106, provide a tubular coupling assembly for coupling the first and second expandable tubular members, 102 and 108, together that may include, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first and second expandable tubular members 12 have a plastic yield point YP-i, and the tubular couplings, 104 and 106, have a plastic yield point YP2. In an exemplary embodiment, the expandable tubular assembly 100 is positioned within a preexisting structure such as, for example, a wellbore 110 that traverses a subterranean formation 112. [00124] As illustrated in Fig. 9, an expansion device 114 may then be positioned within the second expandable tubular member 108. In several exemplary embodiments, the expansion device 114 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services,
Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 114 is positioned within the second expandable tubular member 108 before, during, or after the placement of the expandable tubular assembly 100 within the preexisting structure 110.
[00125] As illustrated in Fig. 10, the expansion device 114 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 108 to form a bell-shaped section.
[00126] As illustrated in Fig. 11 , the expansion device 114 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 108, the tubular couplings, 104 and 106, and at least a portion of the first expandable tubular member 102.
[00127] In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 102 and 108, are radially expanded into intimate contact with the interior surface of the preexisting structure 110.
[00128] In an exemplary embodiment, as illustrated in Fig. 12, the plastic yield point YPi is less than the plastic yield point YP2. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and second expandable tubular members, 102 and 108, is less than the amount of power and/or energy required to radially expand each unit length of the tubular couplings, 104 and 106.
[00129] In an exemplary embodiment, as illustrated in Fig. 13, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility DPE and a yield strength YSPE prior to radial expansion and plastic deformation, and a ductility DAE and a yield strength YSAE after radial expansion and plastic deformation. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YSPE. In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YSAEis greater than YSPE, the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process.
[00130] Referring to Fig. 14, an exemplary embodiment of an expandable tubular assembly 200 includes a first expandable tubular member 202 coupled to a second expandable tubular member 204 that defines radial openings 204a, 204b, 204c, and 204d. In several exemplary embodiments, the ends of the first and second expandable tubular members, 202 and 204, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, one or more of the radial openings, 204a, 204b, 204c, and 204d, have circular, oval, square, and/or irregular cross sections and/or include portions that extend to and interrupt either end of the second expandable tubular member 204. In an exemplary embodiment, the expandable tubular assembly 200 is positioned within a preexisting structure such as, for example, a wellbore 206 that traverses a subterranean formation 208.
[00131] As illustrated in Fig. 15, an expansion device 210 may then be positioned within the second expandable tubular member 204. In several exemplary embodiments, the expansion device 210 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 210 is positioned within the second expandable tubular member 204 before, during, or after the placement of the expandable tubular assembly 200 within the preexisting structure 206.
[00132] As illustrated in Fig. 16, the expansion device 210 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 204 to form a bell-shaped section.
[00133] As illustrated in Fig. 16, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 204 and at least a portion of the first expandable tubular member 202. [00134] In an exemplary embodiment, the anisotropy ratio AR for the first and second expandable tubular members is defined by the following equation: AR = In (WTf/WT0)/ln (Df/D0); where AR = anisotropy ratio; where WTf = final wall thickness of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member; where WT, = initial wall thickness of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member; where Df = final inside diameter of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member; and where Dj = initial inside diameter of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member. [00135] In an exemplary embodiment, the anisotropy ratio AR for the first and/or second expandable tubular members, 204 and 204, is greater than 1. [00136] In an exemplary experimental embodiment, the second expandable tubular member 204 had an anisotropy ratio AR greater than 1 , and the radial expansion and plastic deformation of the second expandable tubular member did not result in any of the openings, 204a, 204b, 204c, and 204d, splitting or otherwise fracturing the remaining portions of the second expandable tubular member. This was an unexpected result. [00137] Referring to Fig. 18, in an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 are processed using a method 300 in which a tubular member in an initial state is thermo-mechanically processed in step 302. In an exemplary embodiment, the thermo-mechanical processing 302 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo- mechanical processing 302, the tubular member is transformed to an intermediate state. The tubular member is then further thermo-mechanically processed in step 304. In an exemplary embodiment, the thermo-mechanical processing 304 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo-mechanical processing 304, the tubular member is transformed to a final state. [00138] In an exemplary embodiment, as illustrated in Fig. 19, during the operation of the method 300, the tubular member has a ductility DPE and a yield strength YSPE prior to the final thermo-mechanical processing in step 304, and a ductility DAE and a yield strength YSAE after final thermo-mechanical processing. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YSPE. In this manner, the amount of energy and/or power required to transform the tubular member, using mechanical forming processes, during the final thermo-mechanical processing in step 304 is reduced. Furthermore, in this manner, because the YSAE is greater than YSPE, the collapse strength of the tubular member is increased after the final thermo-mechanical processing in step 304. [00139] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, have the following characteristics:

[00140] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are characterized by an expandability coefficient f: i. f = r X n ii. where f = expandability coefficient; 1. r = anisotropy coefficient; and 2. n = strain hardening exponent. [00141] In an exemplary embodiment, the anisotropy coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 1. In an exemplary embodiment, the strain hardening exponent for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12. In an exemplary embodiment, the expandability coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12. [00142] In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy to radially expand and plastically deform each unit length than a tubular member having a lower expandability coefficient. In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy per unit length to radially expand and plastically deform than a tubular member having a lower expandability coefficient. [00143] In several exemplary experimental embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are steel alloys having one of the following compositions:

[00148] In an exemplary experimental embodiment, samples of expandable tubulars composed of Alloys A, B, C, and D exhibited the following tensile characteristics prior to radial expansion and plastic deformation:
Figure imgf000032_0002
[00149] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 have a strain hardening exponent greater than 0.12, and a yield ratio is less than 0.85.
[00150] In an exemplary embodiment, the carbon equivalent Ce, for tubular members having a carbon content (by weight percentage) less than or equal to 0.12%, is given by the following expression: Ce = C + Mn/6 + (Cr + Mo + V + Ti + Nb)/5 + (Ni + Cu)/15 where Ce = carbon equivalent value; a. C = carbon percentage by weight; b. Mn = manganese percentage by weight; c. Cr = chromium percentage by weight; d. Mo = molybdenum percentage by weight; e. V = vanadium percentage by weight; f. Ti = titanium percentage by weight; g. Nb = niobium percentage by weight; h. Ni = nickel percentage by weight; and i. Cu = copper percentage by weight.
[00151] In an exemplary embodiment, the carbon equivalent value Ce, for tubular members having a carbon content less than or equal to 0.12% (by weight), for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is less than 0.21.
[00152] In an exemplary embodiment, the carbon equivalent Ce, for tubular members having more than 0.12% carbon content (by weight), is given by the following expression: Ce = C + Si/30 + (Mn + Cu + Cr)/ 20 + Nil 60 + Mo/15 + V /10 + 5 * B where Ce = carbon equivalent value; a. C = carbon percentage by weight; b. Si = silicon percentage by weight; c. Mn = manganese percentage by weight; d. Cu = copper percentage by weight; e. Cr = chromium percentage by weight; f. Ni = nickel percentage by weight; g. Mo = molybdenum percentage by weight; h. V = vanadium percentage by weight; and i. B = boron percentage by weight.
[00153] In an exemplary embodiment, the carbon equivalent value Ce, for tubular members having greater than 0.12% carbon content (by weight), for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is less than 0.36.
[00154] Referring to Fig. 22 in an exemplary embodiment, a first tubular member 2210 includes an internally threaded connection 2212 at an end portion 2214. A first end of a tubular sleeve 2216 that includes an internal flange 2218 having a tapered portion 2220, and a second end that includes a tapered portion 2222, is then mounted upon and receives the end portion 2214 of the first tubular member 2210. In an exemplary embodiment, the end portion 2214 of the first tubular member 2210 abuts one side of the internal flange 2218 of the tubular sleeve 2216, and the internal diameter of the internal flange 2218 of the tubular sleeve 2216 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 2212 of the end portion 2214 of the first tubular member
2210. An externally threaded connection 2224 of an end portion 2226 of a second tubular member 2228 having an annular recess 2230 is then positioned within the tubular sleeve
2216 and threadably coupled to the internally threaded connection 2212 of the end portion
2214 of the first tubular member 2210. In an exemplary embodiment, the internal flange
2218 of the tubular sleeve 2216 mates with and is received within the annular recess 2230 of the end portion 2226 of the second tubular member 2228. Thus, the tubular sleeve 2216 is coupled to and surrounds the external surfaces of the first and second tubular members,
2210 and 2228.
[00155] The internally threaded connection 2212 of the end portion 2214 of the first tubular member 2210 is a box connection, and the externally threaded connection 2224 of the end portion 2226 of the second tubular member 2228 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2216 is at least approximately .020" greater than the outside diameters of the first and second tubular members, 2210 and 2228. In this manner, during the threaded coupling of the first and second tubular members, 2210 and 2228, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00156] As illustrated in Fig. 22, the first and second tubular members, 2210 and
2228, and the tubular sleeve 2216 may be positioned within another structure 2232 such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device 2234 within and/or through the interiors of the first and second tubular members. The tapered portions,
2220 and 2222, of the tubular sleeve 2216 facilitate the insertion and movement of the first and second tubular members within and through the structure 2232, and the movement of the expansion device 2234 through the interiors of the first and second tubular members,
2210 and 2228, may be, for example, from top to bottom or from bottom to top. [00157] During the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, the tubular sleeve 2216 is also radially expanded and plastically deformed. As a result, the tubular sleeve 2216 may be maintained in circumferential tension and the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, may be maintained in circumferential compression.
[00158] Sleeve 2216 increases the axial compression loading of the connection between tubular members 2210 and 2228 before and after expansion by the expansion device 2234. Sleeve 2216 may, for example, be secured to tubular members 2210 and
2228 by a heat shrink fit.
[00159] In several alternative embodiments, the first and second tubular members,
2210 and 2228, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global
Technology L.L.C.
[00160] The use of the tubular sleeve 2216 during (a) the coupling of the first tubular member 2210 to the second tubular member 2228, (b) the placement of the first and second tubular members in the structure 2232, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 2216 protects the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, during handling and insertion of the tubular members within the structure 2232. In this manner, damage to the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations.
Furthermore, the tubular sleeve 2216 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 2228 to the first tubular member 2210. In this manner, misalignment that could result in damage to the threaded connections, 2212 and 2224, of the first and second tubular members, 2210 and 2228, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, the tubular sleeve 2216 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 2216 can be easily rotated, that would indicate that the first and second tubular members, 2210 and 2228, are not fully threadably coupled and in intimate contact with the internal flange 2218 of the tubular sleeve. Furthermore, the tubular sleeve 2216 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 2214 and 2226, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, the tubular sleeve 2216 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve 2216 and the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members. In this manner, fiuidic materials are prevented from passing through the threaded connections, 2212 and 2224, of the first and second tubular members, 2210 and 2228, into the annulus between the first and second tubular members and the structure 2232. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, the tubular sleeve 2216 may be maintained in circumferential tension and the end portions,
2214 and 2226, of the first and second tubular members, 2210 and 2228, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve.
[00161] In several exemplary embodiments, one or more portions of the first and second tubular members, 2210 and 2228, and the tubular sleeve 2216 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00162] Referring to Fig. 23, in an exemplary embodiment, a first tubular member 210 includes an internally threaded connection 2312 at an end portion 2314. A first end of a tubular sleeve 2316 includes an internal flange 2318 and a tapered portion 2320. A second end of the sleeve 2316 includes an internal flange 2321 and a tapered portion 2322. An externally threaded connection 2324 of an end portion 2326 of a second tubular member
2328 having an annular recess 2330, is then positioned within the tubular sleeve 2316 and threadably coupled to the internally threaded connection 2312 of the end portion 2314 of the first tubular member 2310. The internal flange 2318 of the sleeve 2316 mates with and is received within the annular recess 2330.
[00163] The first tubular member 23 0 includes a recess 2331. The internal flange
2321 mates with and is received within the annular recess 2331. Thus, the sleeve 2316 is coupled to and surrounds the external surfaces of the first and second tubular members
2310 and 2328.
[00164] The internally threaded connection 2312 of the end portion 2314 of the first tubular member 2310 is a box connection, and the externally threaded connection 2324 of the end portion 2326 of the second tubular member 2328 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2316 is at least approximately .020" greater than the outside diameters of the first and second tubular members 2310 and 2328. In this manner, during the threaded coupling of the first and second tubular members 2310 and 2328, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00165] As illustrated in Fig. 23, the first and second tubular members 2310 and 2328, and the tubular sleeve 2316 may then be positioned within another structure 2332 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2334 through and/or within the interiors of the first and second tubular members. The tapered portions 2320 and 2322, of the tubular sleeve 2316 facilitates the insertion and movement of the first and second tubular members within and through the structure 2332, and the displacement of the expansion device 2334 through the interiors of the first and second tubular members 2310 and 2328, may be from top to bottom or from bottom to top.
[00166] During the radial expansion and plastic deformation of the first and second tubular members 2310 and 2328, the tubular sleeve 2316 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2316 may be maintained in circumferential tension and the end portions 2314 and 2326, of the first and second tubular members 2310 and 2328, may be maintained in circumferential compression.
[00167] Sleeve 2316 increases the axial tension loading of the connection between tubular members 2310 and 2328 before and after expansion by the expansion device 2334.
Sleeve 2316 may be secured to tubular members 2310 and 2328 by a heat shrink fit.
[00168] In several exemplary embodiments, one or more portions of the first and second tubular members, 2310 and 2328, and the tubular sleeve 2316 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00169] Referring to Fig. 24, in an exemplary embodiment, a first tubular member
2410 includes an internally threaded connection 2412 at an end portion 2414. A first end of a tubular sleeve 2416 includes an internal flange 2418 and a tapered portion 2420. A second end of the sleeve 2416 includes an internal flange 2421 and a tapered portion 2422.
An externally threaded connection 2424 of an end portion 2426 of a second tubular member
2428 having an annular recess 2430, is then positioned within the tubular sleeve 2416 and threadably coupled to the internally threaded connection 2412 of the end portion 2414 of the first tubular member 2410. The internal flange 2418 of the sleeve 2416 mates with and is received within the annular recess 2430. The first tubular member 2410 includes a recess
2431. The internal flange 2421 mates with and is received within the annular recess 2431.
Thus, the sleeve 2416 is coupled to and surrounds the external surfaces of the first and second tubular members 2410 and 2428. [00170] The internally threaded connection 2412 of the end portion 2414 of the first tubular member 2410 is a box connection, and the externally threaded connection 2424 of the end portion 2426 of the second tubular member 2428 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2416 is at least approximately .020" greater than the outside diameters of the first and second tubular members 2410 and 2428. In this manner, during the threaded coupling of the first and second tubular members 2410 and 2428, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00171] As illustrated in Fig. 24, the first and second tubular members 2410 and 2428, and the tubular sleeve 2416 may then be positioned within another structure 2432 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2434 through and/or within the interiors of the first and second tubular members. The tapered portions 2420 and 2422, of the tubular sleeve 2416 facilitate the insertion and movement of the first and second tubular members within and through the structure 2432, and the displacement of the expansion device 2434 through the interiors of the first and second tubular members, 2410 and 2428, may be from top to bottom or from bottom to top.
[00172] During the radial expansion and plastic deformation of the first and second tubular members, 2410 and 2428, the tubular sleeve 2416 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2416 may be maintained in circumferential tension and the end portions, 2414 and 2426, of the first and second tubular members, 2410 and 2428, may be maintained in circumferential compression.
[00173] The sleeve 2416 increases the axial compression and tension loading of the connection between tubular members 2410 and 2428 before and after expansion by expansion device 2424. Sleeve 2416 may be secured to tubular members 2410 and 2428 by a heat shrink fit.
[00174] In several exemplary embodiments, one or more portions of the first and second tubular members, 2410 and 2428, and the tubular sleeve 2416 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00175] Referring to Fig. 25, in an exemplary embodiment, a first tubular member
2510 includes an internally threaded connection 2512 at an end portion 2514. A first end of a tubular sleeve 2516 includes an internal flange 2518 and a relief 2520. A second end of the sleeve 2516 includes an internal flange 2521 and a relief 2522. An externally threaded connection 2524 of an end portion 2526 of a second tubular member 2528 having an annular recess 2530, is then positioned within the tubular sleeve 2516 and threadably coupled to the internally threaded connection 2512 of the end portion 2514 of the first tubular member 2510. The internal flange 2518 of the sleeve 2516 mates with and is received within the annular recess 2530. The first tubular member 2510 includes a recess 2531. The internal flange 2521 mates with and is received within the annular recess 2531. Thus, the sleeve 2516 is coupled to and surrounds the external surfaces of the first and second tubular members 2510 and 2528.
[00176] The internally threaded connection 2512 of the end portion 2514 of the first tubular member 2510 is a box connection, and the externally threaded connection 2524 of the end portion 2526 of the second tubular member 2528 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2516 is at least approximately .020" greater than the outside diameters of the first and second tubular members 2510 and 2528. In this manner, during the threaded coupling of the first and second tubular members 2510 and 2528, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00177] As illustrated in Fig. 25, the first and second tubular members 2510 and 2528, and the tubular sleeve 2516 may then be positioned within another structure 2532 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2534 through and/or within the interiors of the first and second tubular members. The reliefs 2520 and 2522 are each filled with a sacrificial material 2540 including a tapered surface 2542 and 2544, respectively. The material 2540 may be a metal or a synthetic, and is provided to facilitate the insertion and movement of the first and second tubular members 2510 and 2528, through the structure 2532. The displacement of the expansion device 2534 through the interiors of the first and second tubular members 2510 and 2528, may, for example, be from top to bottom or from bottom to top.
[00178] During the radial expansion and plastic deformation of the first and second tubular members 2510 and 2528, the tubular sleeve 2516 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2516 may be maintained in circumferential tension and the end portions 2514 and 2526, of the first and second tubular members, 2510 and 2528, may be maintained in circumferential compression.
[00179] The addition of the sacrificial material 2540, provided on sleeve 2516, avoids stress risers on the sleeve 2516 and the tubular member 2510. The tapered surfaces 2542 and 2544 are intended to wear or even become damaged, thus incurring such wear or damage which would otherwise be borne by sleeve 2516. Sleeve 2516 may be secured to tubular members 2510 and 2528 by a heat shrink fit. [00180] In several exemplary embodiments, one or more portions of the first and second tubular members, 2510 and 2528, and the tubular sleeve 2516 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00181] Referring to Fig. 26, in an exemplary embodiment, a first tubular member
2610 includes an internally threaded connection 2612 at an end portion 2614. A first end of a tubular sleeve 2616 includes an internal flange 2618 and a tapered portion 2620. A second end of the sleeve 2616 includes an internal flange 2621 and a tapered portion 2622.
An externally threaded connection 2624 of an end portion 2626 of a second tubular member
2628 having an annular recess 2630, is then positioned within the tubular sleeve 2616 and threadably coupled to the internally threaded connection 2612 of the end portion 2614 of the first tubular member 2610. The internal flange 2618 of the sleeve 2616 mates with and is received within the annular recess 2630.
[00182] The first tubular member 2610 includes a recess 2631. The internal flange
2621 mates with and is received within the annular recess 2631. Thus, the sleeve 2616 is coupled to and surrounds the external surfaces of the first and second tubular members
2610 and 2628.
[00183] The internally threaded connection 2612 of the end portion 2614 of the first tubular member 2610 is a box connection, and the externally threaded connection 2624 of the end portion 2626 of the second tubular member 2628 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2616 is at least approximately .020" greater than the outside diameters of the first and second tubular members 2610 and 2628. In this manner, during the threaded coupling of the first and second tubular members 2610 and 2628, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00184] As illustrated in Fig. 26, the first and second tubular members 2610 and 2628, and the tubular sleeve 2616 may then be positioned within another structure 2632 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2634 through and/or within the interiors of the first and second tubular members. The tapered portions 2620 and 2622, of the tubular sleeve 2616 facilitates the insertion and movement of the first and second tubular members within and through the structure 2632, and the displacement of the expansion device 2634 through the interiors of the first and second tubular members 2610 and 2628, may, for example, be from top to bottom or from bottom to top.
[00185] During the radial expansion and plastic deformation of the first and second tubular members 2610 and 2628, the tubular sleeve 2616 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2616 may be maintained in circumferential tension and the end portions 2614 and 2626, of the first and second tubular members 2610 and 2628, may be maintained in circumferential compression. [00186] Sleeve 2616 is covered by a thin walled cylinder of sacrificial material 2640.
Spaces 2623 and 2624, adjacent tapered portions 2620 and 2622, respectively, are also filled with an excess of the sacrificial material 2640. The material may be a metal or a synthetic, and is provided to facilitate the insertion and movement of the first and second tubular members 2610 and 2628, through the structure 2632.
[00187] The addition of the sacrificial material 2640, provided on sleeve 2616, avoids stress risers on the sleeve 2616 and the tubular member 2610. The excess of the sacrificial material 2640 adjacent tapered portions 2620 and 2622 are intended to wear or even become damaged, thus incurring such wear or damage which would otherwise be borne by sleeve 2616. Sleeve 2616 may be secured to tubular members 2610 and 2628 by a heat shrink fit.
[00188] In several exemplary embodiments, one or more portions of the first and second tubular members, 2610 and 2628, and the tubular sleeve 2616 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00189] Referring to Fig. 27, in an exemplary embodiment, a first tubular member
2710 includes an internally threaded connection 2712 at an end portion 2714. A first end of a tubular sleeve 2716 includes an internal flange 2718 and a tapered portion 2720. A second end of the sleeve 2716 includes an internal flange 2721 and a tapered portion 2722. An externally threaded connection 2724 of an end portion 2726 of a second tubular member 2728 having an annular recess 2730, is then positioned within the tubular sleeve 2716 and threadably coupled to the internally threaded connection 2712 of the end portion 2714 of the first tubular member 2710. The internal flange 2718 of the sleeve 2716 mates with and is received within the annular recess 2730.
[00190] The first tubular member 2710 includes a recess 2731. The internal flange
2721 mates with and is received within the annular recess 2731. Thus, the sleeve 2716 is coupled to and surrounds the external surfaces of the first and second tubular members 2710 and 2728.
[00191] The internally threaded connection 2712 of the end portion 2714 of the first tubular member 2710 is a box connection, and the externally threaded connection 2724 of the end portion 2726 of the second tubular member 2728 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2716 is at least approximately .020" greater than the outside diameters of the first and second tubular members 2710 and 2728. In this manner, during the threaded coupling of the first and second tubular members 2710 and 2728, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00192] As illustrated in Fig. 27, the first and second tubular members 2710 and 2728, and the tubular sleeve 2716 may then be positioned within another structure 2732 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2734 through and/or within the interiors of the first and second tubular members. The tapered portions 2720 and 2722, of the tubular sleeve 2716 facilitates the insertion and movement of the first and second tubular members within and through the structure 2732, and the displacement of the expansion device 2734 through the interiors of the first and second tubular members 2710 and 2728, may be from top to bottom or from bottom to top.
[00193] During the radial expansion and plastic deformation of the first and second tubular members 2710 and 2728, the tubular sleeve 2716 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2716 may be maintained in circumferential tension and the end portions 2714 and 2726, of the first and second tubular members 2710 and 2728, may be maintained in circumferential compression.
[00194] Sleeve 2716 has a variable thickness due to one or more reduced thickness portions 2790 and/or increased thickness portions 2792.
[00195] Varying the thickness of sleeve 2716 provides the ability to control or induce stresses at selected positions along the length of sleeve 2716 and the end portions 2724 and 2726. Sleeve 2716 may be secured to tubular members 2710 and 2728 by a heat shrink fit.
[00196] In several exemplary embodiments, one or more portions of the first and second tubular members, 2710 and 2728, and the tubular sleeve 2716 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00197] Referring to Fig. 28, in an alternative embodiment, instead of varying the thickness of sleeve 2716, the same result described above with reference to Fig. 27, may be achieved by adding a member 2740 which may be coiled onto the grooves 2739 formed in sleeve 2716, thus varying the thickness along the length of sleeve 2716.
[00198] Referring to Fig. 29, in an exemplary embodiment, a first tubular member
2910 includes an internally threaded connection 2912 and an internal annular recess 2914 at an end portion 2916. A first end of a tubular sleeve 2918 includes an internal flange 2920, and a second end of the sleeve 2916 mates with and receives the end portion 2916 of the first tubular member 2910. An externally threaded connection 2922 of an end portion 2924 of a second tubular member 2926 having an annular recess 2928, is then positioned within the tubular sleeve 2918 and threadably coupled to the internally threaded connection 2912 of the end portion 2916 of the first tubular member 2910. The internal flange 2920 of the sleeve 2918 mates with and is received within the annular recess 2928. A sealing element
2930 is received within the internal annular recess 2914 of the end portion 2916 of the first tubular member 2910.
[00199] The internally threaded connection 2912 of the end portion 2916 of the first tubular member 2910 is a box connection, and the externally threaded connection 2922 of the end portion 2924 of the second tubular member 2926 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2918 is at least approximately .020" greater than the outside diameters of the first tubular member 2910. In this manner, during the threaded coupling of the first and second tubular members 2910 and
2926, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00200] The first and second tubular members 2910 and 2926, and the tubular sleeve
2918 may be positioned within another structure such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device through and/or within the interiors of the first and second tubular members.
[00201] During the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, the tubular sleeve 2918 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2918 may be maintained in circumferential tension and the end portions 2916 and 2924, of the first and second tubular members 2910 and 2926, respectively, may be maintained in circumferential compression.
[00202] In an exemplary embodiment, before, during, and after the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, and the tubular sleeve 2918, the sealing element 2930 seals the interface between the first and second tubular members. In an exemplary embodiment, during and after the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, and the tubular sleeve 2918, a metal to metal seal is formed between at least one of: the first and second tubular members 2910 and 2926, the first tubular member and the tubular sleeve 2918, and/or the second tubular member and the tubular sleeve. In an exemplary embodiment, the metal to metal seal is both fluid tight and gas tight.
[00203] In several exemplary embodiments, one or more portions of the first and second tubular members, 2910 and 2926, the tubular sleeve 2918, and the sealing element
2930 have one or more of the material properties of one or more of the tubular members 12,
14, 24, 26, 102, 104, 106, 108, 202 and/or 204.

108, 202 and/or 204.
[00216] Referring to Fig. 30c, in an exemplary embodiment, a first tubular member
3050 includes internally threaded connections 3052a and 3052b, spaced apart by a cylindrical internal surface 3054 including one or more square grooves 3056, at an end portion 3058. Externally threaded connections 3060a and 3060b, spaced apart by a cylindrical external surface 3062 including one or more square grooves 3064, of an end portion 3066 of a second tubular member 3068 are threadably coupled to the internally threaded connections, 3052a and 3052b, respectively, of the end portion 3058 of the first tubular member 3050. A sealing element 3070 is received within an annulus defined between the cylindrical internal surface 3054 of the first tubular member 3050 and the external cylindrical surface 3062 of the second tubular member 3068.

[00218] The first and second tubular members 3050 and 3068 may be positioned within another structure such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device through and/or within the interiors of the first and second tubular members.

In an exemplary embodiment, before, during and/or after the radial expansion and plastic deformation of the first and second tubular members, 3050 and 3068, a metal to metal seal is formed between at least one of: the first and second tubular members, the first tubular member and the sealing element 3070, and/or the second tubular member and the sealing element.

[00222] Referring to Fig. 31 , in an exemplary embodiment, a first tubular member
3110 includes internally threaded connections, 3112a and 3112b, spaced apart by a non- threaded internal surface 3114, at an end portion 3116. Externally threaded connections, 3118a and 3118b, spaced apart by a non-threaded external surface 3120, of an end portion 3122 of a second tubular member 3124 are threadably coupled to the internally threaded connections, 3112a and 3112b, respectively, of the end portion 3122 of the first tubular member 3124.
[00223] First, second, and/or third tubular sleeves, 3126, 3128, and 3130, are coupled the external surface of the first tubular member 3110 in opposing relation to the threaded connection formed by the internal and external threads, 3112a and 3118a, the interface between the non-threaded surfaces, 3114 and 3120, and the threaded connection formed by the internal and external threads, 3112b and 3118b, respectively.
[00224] The internally threaded connections, 3112a and 3112b, of the end portion
3116 of the first tubular member 3110 are box connections, and the externally threaded connections, 3118a and 3118b, of the end portion 3122 of the second tubular member 3124 are pin connections.
[00225] The first and second tubular members 3110 and 3124, and the tubular sleeves 3126, 3128, and/or 3130, may then be positioned within another structure 3132 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 3134 through and/or within the interiors of the first and second tubular members.
[00226] During the radial expansion and plastic deformation of the first and second tubular members 3110 and 3124, the tubular sleeves 3126, 3128 and/or 3130 are also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeves 3126, 3128, and/or 3130 are maintained in circumferential tension and the end portions 3116 and 3122, of the first and second tubular members 3110 and 3124, may be maintained in circumferential compression.
[00227] The sleeves 3126, 3128, and/or 3130 may, for example, be secured to the first tubular member 3110 by a heat shrink fit.
[00228] In several exemplary embodiments, one or more portions of the first and second tubular members, 3110 and 3124, and the sleeves, 3126, 3128, and 3130, have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102,
104, 106, 108, 202 and/or 204.
[00229] Referring to Fig. 32a, in an exemplary embodiment, a first tubular member
3210 includes an internally threaded connection 3212 at an end portion 3214. An externally threaded connection 3216 of an end portion 3218 of a second tubular member 3220 are threadably coupled to the internally threaded connection 3212 of the end portion 3214 of the first tubular member 3210.
[00230] The internally threaded connection 3212 of the end portion 3214 of the first tubular member 3210 is a box connection, and the externally threaded connection 3216 of the end portion 3218 of the second tubular member 3220 is a pin connection. [00231] A tubular sleeve 3222 including internal flanges 3224 and 3226 is positioned proximate and surrounding the end portion 3214 of the first tubular member 3210. As illustrated in Fig. 32b, the tubular sleeve 3222 is then forced into engagement with the external surface of the end portion 3214 of the first tubular member 3210 in a conventional manner. As a result, the end portions, 3214 and 3218, of the first and second tubular members, 3210 and 3220, are upset in an undulating fashion.
[00232] The first and second tubular members 3210 and 3220, and the tubular sleeve
3222, may then be positioned within another structure such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device through and/or within the interiors of the first and second tubular members.
[00233] During the radial expansion and plastic deformation of the first and second tubular members 3210 and 3220, the tubular sleeve 3222 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 3222 is maintained in circumferential tension and the end portions 3214 and 3218, of the first and second tubular members 3210 and 3220, may be maintained in circumferential compression.
[00234] In several exemplary embodiments, one or more portions of the first and second tubular members, 3210 and 3220, and the sleeve 3222 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00235] Referring to Fig. 33, in an exemplary embodiment, a first tubular member
3310 includes an internally threaded connection 3312 and an annular projection 3314 at an end portion 3316.
[00236] A first end of a tubular sleeve 3318 that includes an internal flange 3320 having a tapered portion 3322 and an annular recess 3324 for receiving the annular projection 3314 of the first tubular member 3310, and a second end that includes a tapered portion 3326, is then mounted upon and receives the end portion 3316 of the first tubular member 3310.
[00237] In an exemplary embodiment, the end portion 3316 of the first tubular member 3310 abuts one side of the internal flange 3320 of the tubular sleeve 3318 and the annular projection 3314 of the end portion of the first tubular member mates with and is received within the annular recess 3324 of the internal flange of the tubular sleeve, and the internal diameter of the internal flange 3320 of the tubular sleeve 3318 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310. An externally threaded connection
3326 of an end portion 3328 of a second tubular member 3330 having an annular recess
3332 is then positioned within the tubular sleeve 3318 and threadably coupled to the internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310. In an exemplary embodiment, the internal flange 3332 of the tubular sleeve 3318 mates with and is received within the annular recess 3332 of the end portion 3328 of the second tubular member 3330. Thus, the tubular sleeve 3318 is coupled to and surrounds the external surfaces of the first and second tubular members, 3310 and 3328.
[00238] The internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310 is a box connection, and the externally threaded connection 3326 of the end portion 3328 of the second tubular member 3330 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 3318 is at least approximately .020" greater than the outside diameters of the first and second tubular members, 3310 and 3330. In this manner, during the threaded coupling of the first and second tubular members, 3310 and 3330, fiuidic materials within the first and second tubular members may be vented from the tubular members.
[00239] As illustrated in Fig. 33, the first and second tubular members, 3310 and
3330, and the tubular sleeve 3318 may be positioned within another structure 3334 such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device 3336 within and/or through the interiors of the first and second tubular members. The tapered portions,
3322 and 3326, of the tubular sleeve 3318 facilitate the insertion and movement of the first and second tubular members within and through the structure 3334, and the movement of the expansion device 3336 through the interiors of the first and second tubular members,
3310 and 3330, may, for example, be from top to bottom or from bottom to top.
[00240] During the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, the tubular sleeve 3318 is also radially expanded and plastically deformed. As a result, the tubular sleeve 3318 may be maintained in circumferential tension and the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, may be maintained in circumferential compression.
[00241] Sleeve 3316 increases the axial compression loading of the connection between tubular members 3310 and 3330 before and after expansion by the expansion device 3336. Sleeve 3316 may be secured to tubular members 3310 and 3330, for example, by a heat shrink fit.
[00242] In several alternative embodiments, the first and second tubular members,
3310 and 3330, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global
Technology L.L.C. [00243] The use of the tubular sleeve 3318 during (a) the coupling of the first tubular member 3310 to the second tubular member 3330, (b) the placement of the first and second tubular members in the structure 3334, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 3318 protects the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, during handling and insertion of the tubular members within the structure 3334. In this manner, damage to the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations.
Furthermore, the tubular sleeve 3318 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 3330 to the first tubular member 3310. In this manner, misalignment that could result in damage to the threaded connections, 3312 and 3326, of the first and second tubular members, 3310 and 3330, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, the tubular sleeve 3318 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 3318 can be easily rotated, that would indicate that the first and second tubular members, 3310 and 3330, are not fully threadably coupled and in intimate contact with the internal flange 3320 of the tubular sleeve. Furthermore, the tubular sleeve 3318 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 3316 and 3328, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, the tubular sleeve 3318 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve 3318 and the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members. In this manner, fiuidic materials are prevented from passing through the threaded connections, 3312 and 3326, of the first and second tubular members, 3310 and 3330, into the annulus between the first and second tubular members and the structure 3334. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, the tubular sleeve 3318 may be maintained in circumferential tension and the end portions,
3316 and 3328, of the first and second tubular members, 3310 and 3330, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve. [00244] In several exemplary embodiments, one or more portions of the first and second tubular members, 3310 and 3330, and the sleeve 3318 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106,
108, 202 and/or 204.
[00245] Referring to Figs. 34a, 34b, and 34c, in an exemplary embodiment, a first tubular member 3410 includes an internally threaded connection 1312 and one or more external grooves 3414 at an end portion 3416.
[00246] A first end of a tubular sleeve 3418 that includes an internal flange 3420 and a tapered portion 3422, a second end that includes a tapered portion 3424, and an intermediate portion that includes one or more longitudinally aligned openings 3426, is then mounted upon and receives the end portion 3416 of the first tubular member 3410.
[00247] In an exemplary embodiment, the end portion 3416 of the first tubular member 3410 abuts one side of the internal flange 3420 of the tubular sleeve 3418, and the internal diameter of the internal flange 3420 of the tubular sleeve 3416 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 3412 of the end portion 3416 of the first tubular member 3410. An externally threaded connection
3428 of an end portion 3430 of a second tubular member 3432 that includes one or more internal grooves 3434 is then positioned within the tubular sleeve 3418 and threadably coupled to the internally threaded connection 3412 of the end portion 3416 of the first tubular member 3410. In an exemplary embodiment, the internal flange 3420 of the tubular sleeve
3418 mates with and is received within an annular recess 3436 defined in the end portion
3430 of the second tubular member 3432. Thus, the tubular sleeve 3418 is coupled to and surrounds the external surfaces of the first and second tubular members, 3410 and 3432.
[00248] The first and second tubular members, 3410 and 3432, and the tubular sleeve
3418 may be positioned within another structure such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device within and/or through the interiors of the first and second tubular members. The tapered portions, 3422 and 3424, of the tubular sleeve 3418 facilitate the insertion and movement of the first and second tubular members within and through the structure, and the movement of the expansion device through the interiors of the first and second tubular members, 3410 and 3432, may be from top to bottom or from bottom to top.
[00249] During the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the tubular sleeve 3418 is also radially expanded and plastically deformed. As a result, the tubular sleeve 3418 may be maintained in circumferential tension and the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, may be maintained in circumferential compression. [00250] Sleeve 3416 increases the axial compression loading of the connection between tubular members 3410 and 3432 before and after expansion by the expansion device. The sleeve 3418 may be secured to tubular members 3410 and 3432, for example, by a heat shrink fit.
[00251] During the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the grooves 3414 and/or 3434 and/or the openings 3426 provide stress concentrations that in turn apply added stress forces to the mating threads of the threaded connections, 3412 and 3428. As a result, during and after the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the mating threads of the threaded connections, 3412 and 3428, are maintained in metal to metal contact thereby providing a fluid and gas tight connection. In an exemplary embodiment, the orientations of the grooves 3414 and/or 3434 and the openings 3426 are orthogonal to one another. In an exemplary embodiment, the grooves 3414 and/or 3434 are helical grooves.
[00252] In several alternative embodiments, the first and second tubular members,
3410 and 3432, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global
Technology L.L.C.
[00253] The use of the tubular sleeve 3418 during (a) the coupling of the first tubular member 3410 to the second tubular member 3432, (b) the placement of the first and second tubular members in the structure, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 3418 protects the exterior surfaces of the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, during handling and insertion of the tubular members within the structure. In this manner, damage to the exterior surfaces of the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, the tubular sleeve 3418 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 3432 to the first tubular member 3410. In this manner, misalignment that could result in damage to the threaded connections, 3412 and 3428, of the first and second tubular members, 3410 and 3432, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, the tubular sleeve 3416 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 3418 can be easily rotated, that would indicate that the first and second tubular members, 3410 and 3432, are not fully threadably coupled and in intimate contact with the internal flange 3420 of the tubular sleeve. Furthermore, the tubular sleeve 3418 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 3410 and
3432. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 3416 and 3430, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the tubular sleeve
3418 may provide a fluid and gas tight metal-to-metal seal between interior surface of the tubular sleeve 3418 and the exterior surfaces of the end portions, 3416 and 3430, of the first and second tubular members. In this manner, fiuidic materials are prevented from passing through the threaded connections, 3412 and 3430, of the first and second tubular members,
3410 and 3432, into the annulus between the first and second tubular members and the structure. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the tubular sleeve 3418 may be maintained in circumferential tension and the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve.
[00254] In several exemplary embodiments, the first and second tubular members described above with reference to Figs. 1 to 34c are radially expanded and plastically deformed using the expansion device in a conventional manner and/or using one or more of the methods and apparatus disclosed in one or more of the following: The present application is related to the following: (1 ) U.S. patent application serial no. 09/454,139, attorney docket no. 25791.03.02, filed on 12/3/1999, (2) U.S. patent application serial no.

[00255] Referring to Fig. 35a an exemplary embodiment of an expandable tubular member 3500 includes a first tubular region 3502 and a second tubular portion 3504. In an exemplary embodiment, the material properties of the first and second tubular regions, 3502 and 3504, are different. In an exemplary embodiment, the yield points of the first and second tubular regions, 3502 and 3504, are different. In an exemplary embodiment, the yield point of the first tubular region 3502 is less than the yield point of the second tubular region 3504. In several exemplary embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 incorporate the tubular member 3500.
[00256] Referring to Fig. 35b, in an exemplary embodiment, the yield point within the first and second tubular regions, 3502a and 3502b, of the expandable tubular member 3502 vary as a function of the radial position within the expandable tubular member. In an exemplary embodiment, the yield point increases as a function of the radial position within the expandable tubular member 3502. In an exemplary embodiment, the relationship between the yield point and the radial position within the expandable tubular member 3502 is a linear relationship. In an exemplary embodiment, the relationship between the yield point and the radial position within the expandable tubular member 3502 is a non-linear relationship. In an exemplary embodiment, the yield point increases at different rates within the first and second tubular regions, 3502a and 3502b, as a function of the radial position within the expandable tubular member 3502. In an exemplary embodiment, the functional relationship, and value, of the yield points within the first and second tubular regions, 3502a and 3502b, of the expandable tubular member 3502 are modified by the radial expansion and plastic deformation of the expandable tubular member.

In this manner, the hard phase provides high strength, the soft phase provides ductility, and the transitionary phase transitions to a hard phase, such as martensite, during a radial expansion and plastic deformation. Furthermore, in this manner, the yield point of the tubular member increases as a result of the radial expansion and plastic deformation. Further, in this manner, the tubular member is ductile, prior to the radial expansion and plastic deformation, thereby facilitating the radial expansion and plastic deformation.

A pair of radial passages, 3902f and 3902g, defined by the base member 3902 are positioned on opposite sides of flange 3902b, extending from the passage 3902a and through the base member 3902, and each include respective flow control valves, 3902fa and 3902ga, respectively, operable to open and close their respective radial passages. A tubular housing
3904 defines a centrally positioned longitudinal passage 3904a that receives and mates with base member 3902 and defines an internal annular recess 3904b that receives and mates with the external flange 3902b of the base member 3902. A pair of passages. 3904c and
3904d, defined by the tubular housing 3904 are positioned on opposite sides of the tubular housing 3904 and extend through the tubular housing 3904, with each including respective flow control valves, 3904ca and 3904da, respectively, operable to open and close their respective passages. A plurality of circumferentially spaced apart mounting members 3904e are coupled to an end face of the tubular housing 3904. The ends of a plurality of links 3906 are pivotably coupled to corresponding mounting members 3904e on tubular housing 3904.
The ends of a plurality of expansion segments 3908 are pivotably coupled to the other ends of corresponding links 3906 and are mounted upon, supported by, and circumferentially distributed about the circumference of the tapered external conical flange 3902d of the base member 3902. In an exemplary embodiment, the other ends of the expansion segments
3908 include a channel 3908a and a tooth 3908b adjacent the channel 3908a and extending from the expansion segment 3908 in a circumferential direction and into the channel 3908a of the adjacent expansion segment 3908, resulting in adjacent expansion segments 3908 overlapping each other in the circumferential direction.
[00278] In an exemplary embodiment, the external surface of the expansion segments
3908 may be, for example, linear, non-linear, hyperbolic, or a variety of other shapes known in the art. In an exemplary embodiment, materials used for components of the expansion device 3900 have high hardness, high compressive strength, high wear resistance, high corrosion resistance, and high toughness. In an exemplary embodiment, materials used for components of the expansion device 3900 include high chrome based tools steels, high carbon base tool steels, and molybdenum based tool steels such as, for example, DC53 tool steels, D2 tool steels, D3 tool steels, D5 tool steels, D7 tool steels, M2 tool steels, M4 tool steels, CPM M4 tool steels, 10V tool steels and 3V tool steels. In an exemplary embodiment, the working surfaces of the components of expansion device 3900 are hard and wear resistant and coated by methods such as, for example, chemical vapor deposition and physical vapor deposition.
[00279] Referring now to Figs. 39a, 39b, 39c, 39d, 40a, 40b and 40c, in an exemplary embodiment, in operation, expansion device 3900 begins operation with expansion segments 3908 abutting flange 3902c with the tooth 3908b on each expansion segment
3908 extending into the channel 3908a on an adjacent expansion segment 3908, resulting in the expansion segments 3908 overlapping each other in the circumferential direction. In an exemplary embodiment, an end of the expansion device 3900 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a.
The expansion device 3900 may then be expanded by opening flow control valve 3902fa in radial passage 3902f and opening flow control valve 3904da in passage 3904d, and closing flow control valve 3904ca in passage 3904c and closing flow control valve 3902ga in radial passage 3902g, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction AT along the base member 3902. Translation of the tubular housing 3904 in direction AT causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the tooth 3908b on each expansion segment 3908 translates in a circumferential direction through channel 3908a on the adjacent expansion segment 3908, but remains in the channel 3908a, resulting in the expansion segments 3908 continuing to overlap each other in the circumferential direction throughout their translation along the surface of tapered external conical flange 3902d.
[00280] In an exemplary embodiment, the expansion segments 3908 may be retracted by opening flow control valve 3902ga in radial passage 3902g and flow control valve 3904ca in passage 3904c, respectively, and closing flow control valve 3902fa in radial passage 3902f and flow control valve 3904da in passage 3904d, respectively, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction A2 along the base member 3902, bringing expansion segments 3908 back into abutment with flange 3902c.
[00281] In an exemplary embodiment, upon expansion, the expansion segments 3908 may separate from each other in a circumferential direction along a portion of their length while still overlapping each other in the circumferential direction at their ends. In an exemplary embodiment, the overlapping relationship between the expansion segments 3908 prevents axial grooves, or other surface defects, from forming on an inner surface of a tubular member when the expansion device 3900 is displaced axially through that tubular member.
[00282] In an exemplary embodiment, the expansion segments 3908, the flanges
3902c and 3902e, and the tapered external conical flange 3902d provide an adjustable expansion assembly 3912. In an exemplary embodiment, the tubular housing 3904, centrally positioned longitudinal passage 3904a, internal annular recess 3904b, external flange 3902b, passages 3902f, 3902g, 3904c and 3904d, and flow control valves 3902fa,
3902ga, 3904ca and 3904da, provide an actuator 3914. In an exemplary embodiment, actuator 3914 may be a conventional actuator known in the art such as, for example, a hydraulic actuator, an electrical actuator, a mechanical actuator, or a combination thereof. In an exemplary embodiment, the expansion device 3900 may be a conventional adjustable expansion device and/or expansion device 20, 114, 210, 2234, 2334, 2434, 2534, 2634,
2734, or 3134.
[00283] Referring now to Figs. 41 , an alternative embodiment of an expansion system
4000 for expanding a tubular member is substantially identical in design and operation to expansion device 3900 described above with reference to Figs. 39a, 39b, 39c, 39d, 40a, 40b and 40c with the addition of a tubular member 4002. Tubular member 4002 includes an outer surface 4002a, an inner surface 4002b with an inner diameter Dt, a wall thickness
4002c, and defines a passage 4002d extending through the tubular member 4002.
[00284] Referring now to Figs. 39a, 39c, 39d, 40a, 40c, 42a and 42b, in an exemplary embodiment, in operation, expansion device 3900 is positioned in passage 4002d defined by tubular member 4002. Expansion device 3900 begins operation with expansion segments
3908 abutting flange 3902c with the tooth 3908b on each expansion segment 3908 extending into the channel 3908a on an adjacent expansion segment 3908, resulting in the expansion segments 3908 overlapping each other in the circumferential direction. In an exemplary embodiment, the expansion device 3900 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a. In an exemplary embodiment, the expansion segments 3908 have a diameter D^ which is greater than the inner diameter Dt of the tubular member 4002, which causes the tubular member
4002 to radially expand and, due to the overlapping relationship of the expansion segments
3908, is sufficient to allow a pressure drop across the expansion device 3900 to overcome the forces necessary to expand the tubular member 4002 when hydraulic fluid is provided behind the expansion device 3900. In an exemplary embodiment, the percentage increase of tubular member 4002 from inner diameter Dt to diameter D-i is greater than or equal to 1 % of the total desired expansion percentage for the tubular member 4002. In an exemplary embodiment, diameter Di is less than or equal to inner diameter Dt, and a convention sealing method known in the art is used to allow a pressure drop across the expansion device 3900 in order to overcome the forces necessary to expand the tubular member 4002 when hydraulic fluid is provided behind the expansion device 3900. The expansion device
3900 may then be expanded by opening flow control valve 3902fa in radial passage 3902f and opening flow control valve 3904da in passage 3904d, and closing flow control valve
3904ca in passage 3904c and closing flow control valve 3902ga in radial passage 3902g, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction B^ along the base member
3902. Translation of the tubular housing 3904 in direction ^ causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the tooth 3908b on each expansion segment 3908 translates in a circumferential direction through channel 3908a on the adjacent expansion segment
3908, but remains in the channel 3908a, resulting in the expansion segments 3908 continuing to overlap each other throughout their translation along the surface of tapered external conical flange 3902d. Upon expansion, the expansion segments 3908 have a diameter D2 which is greater than the diameter Dt of the tubular member 4002, which causes the tubular member 4002 to radially expand and plastically deform and, due to the overlapping relationship of the expansion segments 3908, is sufficient to allow a pressure drop across the expansion device 3900 to overcome the forces necessary to expand the tubular member 4002 when hydraulic fluid is provided behind the expansion device 3900.
[00285] In an exemplary embodiment, hydraulic fluid may then be provided through the centrally located longitudinal passage 3902a to create a pressure drop across the adjustable expansion assembly 3912 sufficient to overcome the force necessary to radially expand and plastically deform the tubular member 4002, displacing the expansion device
3900 axially through the tubular member 4002 in a direction B2. Furthermore, in several exemplary embodiments, the expansion device 3900 may be displaced, including translation and/or rotation, relative to the tubular member 4002 using a variety of conventional methods known in the art.
[00286] In an exemplary embodiment, before, during, or after the relative displacement of the expansion device 3900 through the tubular member 4002, the expansion segments 3908 may be retracted by opening flow control valve 3902ga in radial passage 3902g and opening flow control valve 3904ca in passage 3904c, and closing flow control valve 3902fa in radial passage 3902f and closing flow control valve 3904da in passage 3904d, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in direction B2 along the base member 3902, bringing expansion segments 3908 back into abutment with flange
3902c.
[00287] In an exemplary embodiment, the tubular member 4002 may be, for example, tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428,
2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068,
3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, or 3500, or a tubular assembly such as, for example, tubular assembly 10, 22, 100, or 200. In an exemplary embodiment, upon expansion, the expansion segments 3908 may separate from each other in a circumferential direction along a portion of their length while still overlapping each other in the circumferential direction at their ends, and using a conventional lubrication system known in the art, a lubricant may be injected between the expansion segments 3908 and the inner surface 4002b of tubular member 4002 to provide lubrication between the adjustable expansion assembly 3912 and the tubular member 4002.
[00288] Referring now to Figs. 43a and 43b, an alternative embodiment of an expansion device 4100 for expanding a tubular member is substantially identical in design and operation to expansion device 3900 described above with reference to Figs. 39a, 39b,
39c, 39d, 40a, 40b and 40c with the addition of a tapered conical preliminary expansion member 4102 and a lubrication system 4104. Preliminary expansion member 4102 is coupled to base member 3902 adjacent actuator 3914. A lubrication system 4104 is coupled to the base member 3902 adjacent the preliminary expansion member 4102 and includes a plurality of lubrication vents 4104a open to the surface of preliminary expansion member
4102. The lubrication vents 4104a are coupled to a lubrication reservoir 4104b which includes a piston 4104c and a piston actuator 4104d. In an exemplary embodiment, the lubrication system 4104 may be a conventional commercially available lubrication system, and/or one or more of the lubrication systems described in PCT patent application serial number , attorney docket number 25791.305.02, filed on 9/7/2004, which is herein incorporated by reference. In an exemplary embodiment, the lubrication system 4104 may be a convention commercially available lubrication system, and/or the lubrication system described in PCT patent application serial number , attorney docket number 25791.307.02, filed on 9/7/2004, which is herein incorporated by reference.
[00289] Referring now to Figs. 43a, 43b and 43c, in an exemplary embodiment, in operation, expansion device 4100 begins operation with expansion segments 3908 abutting flange 3902c and overlapping each other in the circumferential direction. In an exemplary embodiment, the expansion device 4100 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a. The expansion device
4100 may then be expanded by opening flow control valve 3902fa in radial passage 3902f and opening flow control valve 3904da in passage 3904d, and closing flow control valve
3904ca in passage 3904c and closing flow control valve 3902ga in radial passage 3902g, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction d along the base member
3902. Translation of the tubular housing 3904 in direction Ci causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the expansion segments 3908 continue to overlap each other in the circumferential direction throughout their translation.
[00290] In an exemplary embodiment, the expansion segments 3908 may be retracted by opening flow control valve 3902ga in radial passage 3902g and opening flow control valve 3904ca in passage 3904c, and closing flow control valve 3902fa in radial passage 3902f and closing flow control valve 3904da in passage 3904d, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange
3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction C2 along the base member 3902, bringing expansion segments 3908 back into abutment with flange 3902c.
[00291] In an exemplary embodiment, upon expansion, the expansion segments 3908 may separate from each other in a circumferential direction along a portion of their length while still overlapping each other in the circumferential direction at their ends. In an exemplary embodiment, the expansion device 4100 may be a conventional adjustable expansion device and/or expansion device 20, 114, 210, 2234, 2334, 2434, 2534, 2634,
2734, or 3134.
[00292] Referring now to Figs. 41, 44a and 44b, an alternative embodiment of an expansion system 4200 for expanding a tubular member is substantially identical in design and operation to expansion device 4100 described above with reference to Figs. 43a and
43b with the addition of tubular member 4002 which includes an outer surface 4002a, an inner surface 4002b with an inner diameter Dt, a thickness 4002c, and defines a passageway 4002d extending through the tubular member 4002.
[00293] Referring now to Figs. 39a, 39b, 39c, 39d, 40a, 40b, 40c, 44a, and 44b, in an exemplary embodiment, in operation, the expansion device 4100 is positioned in the passage 4002d defined by tubular member 4002. The expansion device 4100 begins operation with expansion segments 3908 abutting flange 3902c and overlapping each other in the circumferential direction. The preliminary expansion member 4102 has a diameter D3 which is greater than the inner diameter Dt of the tubular member 4002, which causes the tubular member 4002 to radially expand and is sufficient to allow a pressure drop across the expansion device 4100 to overcome the forces necessary to expand the tubular member
4002 when hydraulic fluid is provided behind the expansion device 4100. In an exemplary embodiment, the percentage increase of tubular member 4002 from inner diameter Dt to diameter D3 is greater than or equal to 1% of the total desired expansion percentage for the tubular member 4002. In an exemplary embodiment, the expansion device 4100 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a. The expansion device 4100 may then be expanded by opening flow control valve 3902fa in radial passage 3902f and opening flow control valve 3904da in passage
3904d, and closing flow control valve 3904ca in passage 3904c and closing flow control valve 3902ga in radial passage 3902g, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction D^ along the base member 3902. Translation of the tubular housing 3904 in direction D-] causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the expansion segments
3908 continue to overlap each other in the circumferential direction throughout their translation. Upon expansion, the expansion segments 3908 have a diameter D4 which is greater than the diameter Dt of the tubular member 4002, which causes the tubular member
4002 to radially expand and plastically deform.
[00294] In an exemplary embodiment, hydraulic fluid may then be provided through the centrally located longitudinal passage 3902a to create a pressure drop across the preliminary expansion member 4102 sufficient to overcome the force necessary to radially expand and plastically deform the tubular member 4002, displacing the expansion device
4100 axially through the tubular member 4002 in a direction D2. Furthermore, in several exemplary embodiments, the expansion device 4100 may be displaced, including translation and/or rotation, relative to the tubular member 4002 using a variety of conventional methods known in the art.
[00295] In an exemplary embodiment, lubrication may be provided between the preliminary expansion member 4102 and the tubular member 4002 by actuating the piston actuators 4104d to decrease the volume of the lubrication reservoir 4104b and provide lubrication through the lubrication vents 4104a.
[00296] In an exemplary embodiment, before, during, or after the relative displacement of the expansion device 4100 through the tubular member 4002, the expansion segments 3908 may be retracted by opening flow control valve 3902ga in radial passage 3902g and opening flow control valve 3904ca in passage 3904c, and closing flow control valve 3902fa in radial passage 3902f and closing flow control valve 3904da in passage 3904d, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in direction D2 along the base member 3902, bringing expansion segments 3908 back into abutment with flange 3902c. In an exemplary embodiment, the tubular member 4002 may be, for example, tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428, 2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068, 3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, or 3500, or a tubular assembly such as, for example, tubular assembly 10, 22, 100, or 200.
[00297] Referring now to Fig. 45a, an alternative embodiment of an expansion device
4300 for expanding a tubular member is substantially identical in design and operation to expansion devices 3900 and 4100 described above with reference to Figs. 39a, 39b, 39c, 39d, 40a, 40b, 40c, 43a, 43b, and 43c with the addition of a actuator 4302 replacing the actuator 3914. Actuator 4302 includes tubular housing 4302a defining a centrally positioned longitudinal passage 4302b that receives and mates with base member 3902 and defining an internal annular recess 4302c. An annular threaded section 4302d extends from tubular housing 4302a, into internal annular recess 4302c, and into engagement with a radial threaded section 4302e extending from the base member 3902. A rotational actuator 4302f is coupled to the base member 3902 and the base member 3902 includes a rotational coupling 4302g which allows the section of base member 3902 including radial threaded section 4302e to rotate relative to the section of base member 3902 including tapered external conical flange 3902d.
[00298] Referring now to Figs. 39a, 40a, 45a, 45b, and 45c, in an exemplary embodiment, in operation, expansion device 4300 begins operation with expansion segments 3908 abutting flange 3902c with the expansion segments 3908 overlapping each other in the circumferential direction. In an exemplary embodiment, the expansion device 4300 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a. The expansion device 4300 may then be expanded by actuating the actuator 4302f and rotating the base 3902 which, due to the interaction of annular threaded section 4302d and radial threaded section 4302e, causes the tubular housing 3904 to translate in a direction E-, along the base member 3902. Translation of the tubular housing 3904 in direction E-, causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the expansion segments 3908 continuing to overlap each other in the circumferential direction throughout their translation along the surface of tapered external conical flange 3902d. [00299] In an exemplary embodiment, actuator 4302 may be locked in place at an intermediate location along the tapered external conical member 3902d, as illustrated in Fig.
45b, securing expansion segments 3908 in an intermediate position along tapered external conical flange 3902d. In an exemplary embodiment, the expansion segments 3908 may be actuated into engagement with the flange 3902e.
[00300] In an exemplary embodiment, he expansion segments 3908 may be retracted by actuating the actuator 4302f and rotating the base 3902 which, due to the interaction of annular threaded section 4302d and radial threaded section 4302e, causes the tubular housing 3904 to translate in a direction E2 along the base member 3902, causing the tubular housing 3904 to translate along the base member 3902, bringing expansion segments 3908 back into abutment with flange 3902c. In an exemplary embodiment, upon expansion, the expansion segments 3908 may separate from each other in a circumferential direction along a portion of their length while still overlapping each other in the circumferential direction at their ends. In an exemplary embodiment, the expansion device 3900 may be a conventional adjustable expansion device and/or expansion device 20, 114, 210, 2234, 2334, 2434, 2534,
2634, 2734, or 3134.
[00301] In an exemplary embodiment, the expansion device 4300 may be operated as described above with reference to expansion devices 3900 and 4100 and expansion systems 4000 and 4200, illustrated in Figs. 39a, 39b, 39c, 39d, 40a, 40b, 40c, 41 , 42a, 42b,
43a, 43b, 43c, 44a, and 44b.
[00302] Referring now to Fig. 46, an alternative embodiment of an expansion device
4400 for expanding a tubular member is substantially identical in design and operation to expansion device 3900 described above with reference to Figs. 39a, 39b, 39c, 39d, 40a, 40b and 40c with the addition of a actuator 4402 coupled to the base member 3902 adjacent the actuator 3914 and a cylindrical support member 4404 coupled to the base member 3902 adjacent the translating member 4402. The actuator 4402 includes a conventional actuator and, in an exemplary embodiment, may be, for example, a hydraulic actuator, a mechanical actuator, an electrical actuator, or combinations thereof. The cylindrical support member
4404 is flexibly coupled to the translating member 4402 by couplings 4404a and 4404b and defines a centrally located longitudinal passage 4404c for mating with the base member
3092 and includes a plurality of securing members 4404d about its circumference. A radial passage 4406 is defined by the base member 3902 and includes a flow control valve 4406a for opening and closing the radial passage 4406.
[00303] Referring now to Figs. 39a, 39b, 39c, 39d, 40a, 40b, 40c, 41 , 47a, 47b, and
47c, in an exemplary embodiment, in operation, the expansion device 4400 is positioned in the passageway 4002d defined by tubular member 4002. Expansion device 4400 begins operation with expansion segments 3908 abutting flange 3902c and overlapping each other in the circumferential direction. In an exemplary embodiment, the expansion device 4400 is coupled to a tubular coupling 3910 such as, for example, a drill string or other tubular members known in the art, which may provide a hydraulic fluid to the centrally positioned longitudinal passage 3902a. The expansion device 4400 may then be expanded by opening flow control valve 3902fa in radial passage 3902f and opening flow control valve 3904da in passage 3904d, and closing flow control valve 3904ca in passage 3904c and closing flow control valve 3902ga in radial passage 3902g, allowing hydraulic fluid to enter and exit internal annular recess 3904b on opposite sides of the external flange 3902b, resulting in a pressure differential across external flange 3902b that causes the tubular housing 3904 to translate in a direction F^ along the base member 3902. Translation of the tubular housing
3904 in direction Ft causes the expansion segments 3908 to translate along the surface of tapered external conical flange 3902d through the pivotal coupling of the expansion segments 3908 and the tubular housing 3904 by links 3906. During the translation of the expansion segments 3908 along the tapered external conical flange 3902d, the expansion segments 3908 continue to overlap each other throughout their translation along the surface of tapered external conical flange 3902d. Upon expansion, the expansion segments 3908 have a diameter D5 which is greater than the diameter Dt of the tubular member 4002, which causes the tubular member 4002 to radially expand and plastically deform.
[00304] In an exemplary embodiment, the expansion device 4400 may then be displaced axially through the tubular member 4002, radially expanding and plastically deforming the tubular member 4002 along its length, by first opening the flow control valve
4406a in passage 4406 and allowing hydraulic fluid to create a pressure differential across cylindrical support member 4404, displacing the cylindrical support member 4404 through the tubular member 4002 in a direction F2 and extending couplings 4404a and 4404b. The securing members 4404d on cylindrical support member 4404 may then be activated, securing the cylindrical support member 4404 to the inner surface 4002b of tubular member
4002. With the cylindrical support member 4404 secured in the tubular member 4002, the actuator 4402 may then be actuated, which displaces the expansion device 4400 in a direction F2 towards the cylindrical support member 4404 and axially through the tubular member 4002 using cylindrical support member 4404 as a support, radially expanding and plastically deforming the tubular member 4002 from diameter Dt to diameter D .
