Definitions
- the field of this invention is the method of running a tubular inside casing and securing it and more particularly to techniques for protecting the mounting location for the tubular on the casing as the casing is cemented and thereafter cementing the liner after it is expanded into the mounting location.
- Figure 1 is illustrative of the prior techniques of running in casing with a casing shoe 16 near its lower end. If later a tubular is run in and needs to be attached to the casing by expansion, the presence of cement debris in the support area on the casing where the tubular will be attached could prevent a sealed connection from being obtained. One way around that would be to deliver the cement into a shoe mounted below the point at which the liner will be attached later. Another method would be to run brushes and scrapers into the mounting location after cementing to be sure it was clean so that a good seal and support for the tubular subsequently installed can be obtained. However these techniques require significant amounts of time and create an associated cost.
- the present invention protects the mounting location on the casing during cementing with a barrier sleeve that covers a recess.
- the barrier sleeve defines a sealed annular space that contains an incompressible material. This allows the barrier sleeve to be compliant to changes in hydrostatic pressure as the casing is lowered into place. Cementing is done through the barrier sleeve.
- the barrier sleeve is subsequently drilled out exposing a recess and a locating profile and optionally a sliding sleeve valve.
- the tubular can then be positioned accurately using the locating profile and a collet mechanism on the expansion tool and expanded in to sealing contact with the casing.
- the drift diameter of the tubular after expansion into the recess is at least as large as the casing drift diameter.
- the entire tubular can be expanded to its lower end and a run in shoe at the lower end of the tubular can be retrieved and removed from the well with the swaging assembly and the running string that delivered it.
- the sliding sleeve in the casing shoe can be selectively opened and closed with a shifting tool run on the expansion string above the expansion tools, running tool, and the liner to be expanded. Another option is for this sliding sleeve to be located in the liner to be expanded below the upper portion that mounts in the above casing.
- the port opened and closed by this sliding sleeve can be used to either pump cement into the annulus or to return the wellbore fluid displaced by cement from the annulus into the casing string.
- an additional outer sleeve is run on the outside of the recess sleeve.
- This outer sleeve is connected at its lower end to the inner barrier sleeve via a guide nose. The flow path between the outside of the ports and the annulus is opened when the nose is drilled out and under reamed.
- a cement retainer device is to be located at the bottom of the string preventing cement pumped into the annulus from entering into the expanded liner due to density differences.
- This retainer device can be the location from which cement is pumped into the annulus or where the wellbore fluid displaced by the cement is returned from the annulus to the inside of the casing string.
- the cement retainer can be drilled out in a subsequent trip into the hole.
- a barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing.
- a locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve.
- a liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing.
- a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented.
- the cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip.
- a shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve.
- the cement retainer can be milled out in a separate trip.

- Figure 1 illustrates a casing string 10 having a known landing collar 12 and a standard float collar 14 as well as a casing shoe 16 adjacent its lower end l ⁇ .
- the cement is pumped through the casing shoe 16 and then a dart or wiper is used to displace cement from the casing 10 and out through the shoe 16 and into the surrounding annulus.
- a dart or wiper is used to displace cement from the casing 10 and out through the shoe 16 and into the surrounding annulus.
- the shoe 16 is drilled out but residual cement could still be present.
- the presence of such cement or shoe debris after drilling can affect the seal that is subsequently needed when a liner is inserted and secured to the casing 10. This is particularly a concern when the liner is to be expanded to secure it to a recessed mounting location at the bottom of the casing 10.
- the present invention addresses this concern with a barrier sleeve 20 shown in Figures 2 and 15.
- the casing string 22 has a lower section 24.
- a barrier sleeve 20 mounted and defining an annular space 28 that contains an incompressible material 30.
- the incompressible material 30 is loosely mounted sand but other materials can be used.
- the purpose of the material 30 is to control the burst of barrier sleeve 20 and the collapse of recessed mounting location 24 in response to increasing hydrostatic pressures as the depth of the casing 22 increases, when it is lowered into initial position.
- Sleeve 20 is preferably fiberglass sealed at ends 32 and 34.
- Sleeve 20 initially covers locating profile 36 and recessed mounting location 38, which will later serve as the location for securing a tubular such as a liner by a variety of methods. The preferred method of expansion will be described in more detail below.
- Sleeve 20 is preferably a material that can be quickly drilled such as plastics or composites, to mention a few.
- the sleeve 20 has an inner surface 40, which is contacted by the cement.
- a dart or wiper plug 42 passes through casing 22 and lands on landing collar 12 (see Figures 3 & 4) to displace most of the cement out of the casing 22 and into the surrounding annulus.
- the sleeve 20 is subsequently drilled out allowing the incompressible material 30 to escape and exposing the clean locating profile 36 and recessed mounting location 38 for subsequent attachment of a tubular as will be described below.
- the drilling removes all of seal rings 42 and 46 without damaging the casing 22 or recess sleeve 24.
- the method can be understood by beginning at Figure 3, where the casing 22 is mounted in the desired position for cementing in the wellbore 26.
- the assembly includes landing collar 12 and float collar 14.
- the assembly shown in Figure 15 is at the lower end of the assembly, but for clarity only the barrier sleeve 20 is referenced in the schematic illustration.
- Figure 4 shows that cement 48 has been displaced by plug 42 landing on landing collar 12. As a result, cement 48 is pushed through sleeve 20, through run in shoe 50 and into annulus 52.
- Figure 6 illustrates the enlarging of the new section of wellbore 58 to a new dimension 60 using an under-reamer or an RWD bit 62.
- the wellbore 60 can be created in a single trip in the hole or in multiple trips.
- Figure 7 shows the drilling of wellbore 60 complete and the drill string 54 and bit assembly 56 removed from the wellbore 60 and stored at the surface.
- Figure 8 shows a running string 64 that supports a liner or other tubular 66 at locking dogs 68.
- the assembly further comprises an anchor 70 with slips 72 that are preferably pressure sensitive to extend slips 72 and allow them to retract when pressure is removed.
- a piston and cylinder combination 74 that drives a swage 76, in response to pressure applied to the piston and cylinder combination 74.
- pressure is applied to extend the slips 72 and drive down the swage 76 as illustrated schematically by arrows 78.
- the upper end or expandable liner hanger 80 of the tubular 66 is expanded into recessed mounting location 38 for support from casing 22.
- the swage 76 is then stroked enough to suspend the tubular 66 to casing 22.
- FIG. 11 shows the subsequent stroking, further expanding the tubular 66.
- one or more open hole packers 82 can be used to ultimately make sealing contact in wellbore 60 after expansion.
- Figure 12 illustrates the continuation of the movement of the swage in response to applied surface pressure to anchor 70 and piston and cylinder combination 72.
- force magnification can be incorporated into piston and cylinder combination 72 and it is possible for a greater force can be applied to swage 76 at the beginning of each stroke as compared to the balance of each stroke.
- These features were disclosed in co-pending U.S. application Serial Number 60/265,061 whose filing date is February 11, 2002 and whose contents are fully incorporated herein as if fully set forth.
- other techniques can be used for swaging or even to secure the tubular 66 to long recess 38 or another location initially covered by a sleeve such as 20 during cementing of the casing 22, without departing from the invention.
- the run in shoe 84 facilitates insertion of the tubular 66 by presenting a guide nose as the tubular is initially advanced into position, as shown in Figure 8.
- it has a valve in it to check upward flow and allow downward circulation to facilitate insertion of the tubular 66.
- Removal of the run in shoe 84 as described above presents a large opening in the lower end of the tubular 66 to facilitate subsequent drilling operations or other completion techniques.
- FIGs 16-19 show the grasping mechanism 88 in greater detail. It has a top sub 100 connected at thread 102 below dogs 68. Top sub 100 is connected to mandrel 104 at thread 106. The run in shoe 84 is attached to tubular 66 by virtue of ring 108 held against rotation by pin 110, which extends from shoe 84. Threads 112 on ring 108 engage threads 114 on tubular 66. Ring 116 holds ring 112 in position on shoe 84. Shoe 84 has a groove 118 and a stop surface 120. Top sub 100 has a surface 122 that lands on surface 120 as the grasping mechanism 88 advances with the swage 76. When surface 122 hits surface 120 the tubular 66 has not yet been expanded.
- Mandrel 104 has a series of gripping collets 124 that land in groove 118 when surfaces 120 and 122 contact. When this happens, as shown in Figure 16a the collets are aligned with recess 126 on mandrel 104 so that they can enter recess 118 in shoe 84. Mandrel 104 has a ring 128 held on by shear pins 130. When a downward force is applied to shoe 84 through the contact between surfaces 120 and 122, threads 112 and 114 shear out and the shoe 84 drops down and is captured on ring 128. At this point, shown in Figure 17a, surface 132 on mandrel 104 supports collets 124 in groove 118. The shoe 84 is now captured to the mandrel 104.
- the sleeve 20 shields a subsequent mounting location for the tubular 66 on casing 22 from contamination with the cement 48 used in the installation of casing 22.
- the assembly including the sleeve 20 is compliant to changes in hydrostatic pressure resulting from advancement of the casing 22 downhole.
- the lower end of the tubular 66 is left open as the run in shoe 84 is retrieved.
- An incompressible filler material or fluid 208 initially occupies the volume behind the barrier sleeve 204 and inside the recessed mounting location 202, the volume between outer sleeve 210 and recess sleeve 209, and the volume above guide nose 207 and between outer sleeve 210 and barrier sleeve 204.
- This continuous volume containing filler material or fluid 208 will be run in without applied pressure.
- the hydrostatic pressure inside of the barrier sleeve 204, below the guide nose 207, and outside of the outer sleeve 210 will increase as collapse pressure on the items defining the volume.
- Burst disks 203 can be included in the guide nose 207 to allow communication between the volume containing the filler material or fluid 208 and the wellbore the shoe is being run in after a certain differential pressure is reached. This communication equalizes the pressure removing the collapse forces.
- wellbore fluid can enter the filler material or fluid volume and coexist with the filler material or volume 208.
- For run in the sliding sleeve valve 200 is preferably closed rather than the open position shown in Figure 20 but either position can be used because the space occupied by filler material 208 is isolated so no flow can occur though while the casing attached at connection 212 is being cemented. The cement should not enter through the burst disks 203 as the volume is equalized in pressure and captured from flow.
- FIG. 21 A After the casing is cemented, a bit is inserted to drill out the protective assembly of the sleeve 204, centralizers 206, and parts of guide nose 207, as depicted in Figure 21 A.
- the filler material or fluid 208 is removed to the surface with circulation.
- the nose and the wellbore below it are then under reamed and the condition depicted in Figure 21 B is achieved.
- the drilling and under reaming is continued to extend the wellbore to accept the next section of tubular 218
- sliding sleeve valve 200 is exposed as is recessed mounting location 202.
- Port 214 is closed and arrow 216 indicates no flow through it is possible.
- Figure 22 shows the next section of tubular 218 in position and expanded into recessed mounting location 202 and beyond.
- the assembly to do this expansion can include a combination of an anchor and stroker shown schematically as 220 that is connected to a swage 222 that can be of any number of different designs.
- sliding sleeve valve 200 has a groove 224 that is preferably engaged at before expansion of the top of the expanded liner or expandable liner hanger by a collet assembly located on the stroker tool 220 that operates bidirectionally so that on the trip down with the liner 218, the stroker 220 the collet can provide a confirmation indication of overpull or set down weight that the liner is in the proper location for expansion of its top inside of the recessed mounting location 202.
- Tubular string 218 preferably has no external packers to seal the annulus 228 that extends around it. As shown in figure 24, it is possible for a guide nose 230 to be run on the bottom of the expandable liner and retrieved after expansion by a retrieval tool 226 at the bottom of the expansion string.
- FIGs 25 - 29 illustrate a 2 nd trip method of cementing the expanded liner.
- a cement retainer 234 is run in on a work string 236 below a shifting tool 232.
- the cement retainer 234 is to be set at the bottom of liner 218.
- any pressure tests can be performed to confirm that the cement retainer 234 is set properly as valve 200 is closed.
- the running tool 235 for the cement retainer 234 is released and the work string 236 is tripped up hole.
- the shifting tool 232 passes through the valve a similar collet assembly engages the groove 224. With this indication weight is set down and the drill string is turned to the right.
- the shifting tool 232 is located in the sliding sleeve valve 200 and forces the sliding sleeve 200 shut on the way out trapping the cement 237 in the annulus 228.
- Figure 29 shows a separate trip in which the cement retainer 234 is milled out by a drill bit 244 before continuing on to drill the next hole section.
- sliding sleeve valve 200 is located in the top of the expanded liner string 218, just below the mounted section 231. This arrangement is shown in Figure 30. This sliding sleeve valve 200 would be expanded along with the liner string 218 which it is part of to allow for at least as large a drift as the parent casing above it. Once expanded it would be operated as mentioned above and all cementing methods discussed in this application could be applied.
- the primary difference between this method and that detailed above and in Figures 25-29 is that the cement retainer 234 is run in on the same trip as the liner 218 and expansion tools 220.
- Figure 31 illustrates a liner 218 that has been delivered and mounted in the recessed mounting location 202 with the guide shoe 230 and the cement retainer 234 already in place as a combined device 246.
- the sliding sleeve valve 200 can be opened as discussed above by shifting tool 232.
- the expansion tool 220 then returns to expanding the liner string 218.
- cement 237 can be pumped from the surface through the expansion string 236 that extends to the surface.
- the displaced wellbore fluid 239 from cementing go through now open sliding sleeve 200 and to the surface through annulus 240.
- Figure 33 shows the cement 237 pumped into the annulus 228.
- Figure 34 shows the expansion string 236 removed which results in the closure of sliding sleeve valve 200.
- the device 246 has been left in the borehole for a subsequent trip with the mill or bit 244, as shown in Figure 35.
- FIGs 36 and 37 illustrate alternative ways to deliver a cementing shoe 268 to the lower end of a liner 270.
- the shoe 268 is delivered with the liner 270 and sits on or near its bottom during the expansion with the swage 272.
- a gripping device 274 engages the shoe 268 to allow it to pass well fluids in the case of cement being delivered into the annulus 276.
- the gripping device is raised to stop the cement in the annulus 276 from coming • into the liner 270.
- This technique is illustrated in Figures 38-40.
- arrows 278 indicate displaced well fluids from pumping cement represented by arrow 280 through ports 262.
- the cement is delivered down the string 282 and with the help of a diverter device known in the art allows the cement 280 to go down the annulus 270.
- the swage 272 is picked up closing the passages in the shoe 268, as shown in Figure 39.
- the shoe 268 is later drilled or milled as shown with a bit or mill 286.
- the hole may then be drilled deeper and expanded in diameter with under-reamer 288. While introducing cement at the top of the liner has been described those skilled in the art will appreciate that cement can be pumped down through the shoe 268 and well fluid displaced out openings such as 258 or 262, as an alternative technique for cementing.
- Figure 41 shows the expandable tubular or liner 300 delivering a cement isolation device 302 located near the lower end and inside the liner 300.
- Figure 42 is the same except the cement isolation device is extending beyond the lower end of the liner 300.
- the liner 300 is expanded by the swage assembly 304 and the expansion has progressed to near the end of the liner.
- the cement isolation device is captured as the swage assembly 304 finishes the expansion out through the end of the liner 300.
- the swage assembly 304 is raised up positioning the cement isolation device 302 in sealing contact with the liner 300.
- the cement 306 is pumped through the string 308 and the swage assembly 304 and into the annulus 310.
- the cement isolation assembly can employ an actuable seal 314 that can be energized by pressure or mechanically or in other ways to seal against the inner wall of the liner 300 when brought back inside it.
- the ability to take the device 302 right through the liner 300 allows the swage assembly 304 to go clean through to the end of the liner 300 in expanding it.
- the actuable seal 314 then allows the device 302 to seal against the now enlarged liner 300.
- the device 302 can be made of soft metals or non-metallic materials to shorten milling time shown in Figure 47.
- the advantage to delivering the device 302 below the liner 300 is that it can be larger so that after expansion of the liner 300 and the device 302 needs to be brought back into sealing contact in the liner, the gap to bridge is that much smaller.
- the device 302 can be configured to allow fluid to pass through in one or both directions during run in to facilitate insertion. While the tubular 300 is referred to as a liner other structures involving openings such as screens or slotted liners or casing can also be used in the described method.
- Figures 41-47 illustrate a one trip deliver, expand and cement system.
