- Casing is a protective liner comprising many casing segments threadably coupled at the ends to form an elongated string of pipe.
- the casing string is made up to the desired length and cemented into the borehole by pumping a predetermined volume of cement slurry down through the bore of the casing string and into the casing - borehole annulus along a targeted interval of the borehole.
- the cement liner formed around the casing string reinforces the casing string, isolates the casing from corrosive elements and prevents unwanted cross-flow between geologic formations penetrated by the borehole.

- the drillable cement wiper plugs may be deployed into the bore of the casing string, one ahead of and one behind the cement slurry, to prevent contamination.
- Unwanted delays may result from the need for rigging up cement wiper plug launching assemblies or other tools used for cement placement, and from disconnecting fluid lines and connecting cement lines that feed the cement slurry to the bore of the casing string. Prolonged static conditions prior to cement placement may allow cuttings and debris to settle and accumulate at narrow clearances in the annulus. Too often, the delay between circulating fluid to clean the annulus and placement of cement compromises the quality of the cement liner, and there is a need for minimizing or eliminating the delay in order to improve the quality of the cement liner.

- a string of casing suspended in a borehole may weigh hundreds of thousands of pounds or more, and a robust support structure, such as a derrick, is required to suspend a casing string in the borehole.
- the casing make-up and running tool of present invention is adapted for being supported above the borehole by a support structure, such as a derrick.
- FIG. 1 is an elevation view of one embodiment of the casing make up and running tool of the present invention comprising a top drive 3 having an upwardly disposed lift eye 3A coupled to and supporting a body 3B and a motor drive assembly 4 secured to the body.
- the casing make up and running tool is supported by an overhead load- bearing structure (not shown), such as a derrick, that supports a block 2 with a draw works 2A that cooperates with multiple loops of a cable 1.
- the motor drive assembly 4 of the top drive 3 provides for powered rotation of a generally downwardly disposed drive shaft, or quill 5.
- Fluid flow is provided to the top drive 3 from a pump (not shown) coupled to an inlet to the fluid hose 40.
- the pump discharge (not shown) and the fluid hose 40 form a portion of a fluid conduit for introducing fluid into the bore 32 A of the casing string 32.
- the quill 5 of the top drive 3 has a bore 5A that communicates with fluid hose 40 to form a portion of the fluid conduit, which is described in more detail below.
- the following discussion and the appended drawings refer to and depict, respectively a launcher assembly having, in this embodiment, two spherical balls of different diameters.
- the embodiment of the casing make up and running tool of the present invention shown in Figs. 1 and 2 comprises a launcher assembly 6 comprising a ball or dart dropping apparatus 64 having a ball chamber 65, a ball passageway 86 coupled to a launcher sub 84 having a central bore 88 there through.
- the ball chamber 65 feeds into an inlet 86A of the ball passageway 86, and the outlet 86B of the ball passageway 86 feeds into the bore 88 of the launcher sub 84 so that the ball passageway 86 is openable to place the ball chamber 65 in communication with the bore 88 of the launcher sub 84.
- the bore 88 of the launcher sub 84 is aligned with the bore 5A of the quill 5 of the top drive unit 3.
- the fluid conduit comprises the pump discharge (not shown), the fluid hose 40 providing pressurized fluid to the top drive, the bore 5 A of the quill 5 and the bore 88 of the launcher sub 84, and the fluid conduit comprising these components feeds downwardly into the borehole, through one or more other bores, into the bore 32 A of the casing string 32.
- the launcher sub 84 of the launcher assembly 6 is either fixed to or rotatably secured to the body 3B of the top drive.
- the launcher sub 84 remains stationary when the quill 5 of the top drive unit rotates an extension sleeve that is disposed within the stationary launcher sub 84 of the launcher assembly 6.
- the launcher sub 84 comprises a sub with a swivel seal on the inner quill extension to permit the launcher sub 84 to remain stationary as the quill 5 and the extension rotates with the top drive 3.
- the launcher sub 84 of the launcher assembly 6 is threadably coupled to the quill 5 of the top drive.
- the launcher sub 84 that is threadably coupled to the quill 5 also rotates. Fluid hoses (not shown) used for operation and control of the launcher assembly 6 must be connected to their respective termination sites on the launcher sub 84 after the casing string is fully made up and ready to be lowered into position for cementing in the borehole.
- the ball dropping apparatus 64 may be designed to facilitate loading of balls (see elements 42, 44 in Fig. 4) prior to the cementing phase of well completion. It should be understood that darts having different diameters or other launching members may be substituted for the balls shown in Fig. 4 without loss of function of the launcher assembly or the cement wiper plug assembly, which is described below.
- the launcher sub 84 is rotatably secured to the body 3B of the top drive 3.
- the launcher sub 84 may be rotatable with and secured to the quill 5 of the top drive.
- the fixed and the rotatable embodiments of the launcher sub 84 both are adapted to cooperate with a cement wiper plug assembly (see element 57 in Figs. 2-4) that is described in detail below.
- a launching member such as a ball (see elements 42, 44 in Fig. 5), is launched from the ball chamber 65 through the inlet 86A and then the outlet 86B of the passageway 86 into the bore 88 of the launcher sub 84 to enter the fluid conduit when the cement wiper plug assembly 57 is coupled to the casing make up and running tool to enable controlled placement of cement.
- the launcher assembly 6 also comprises a cement port (see element 66 in 32A Figs. 1, 2 and 4 and element 43 in Fig. 3) for introducing cement slurry into the bore of the quill 5 and, ultimately, into the bore of the casing string 32. Cement may also be introduced into the bore 32 A of the casing string 32 through hose 40.
- the casing make-up and running tool of the present invention also comprises a casing gripping assembly for gripping and suspending a casing string.
- the top drive 3 rotatably supports a gripping assembly 14 that engages and grips the proximal (surface) end 46 of the casing string 32.
- the gripping assembly 14 shown in Figs. 1 and 2 comprises an internally gripping elevator 15 having a generally circumferential arrangement of radially outwardly disposable pipe gripping members 15A.
- the gripping assembly 14 is suspended above the borehole (not shown) and within the bore 32A of the casing string 32 to forcibly engage the internal wall of the casing string 32 to grip and support the casing string 32 in the borehole.
- An actuator 17 is used to urge pipe gripping members 15A into radial engagement with the internal wall of the casing string 32.
- casing fill-up involves introducing fluid into the proximal end 46 of the casing string 32, disposing an outlet of the fluid conduit, such as a nozzle 35, within the bore 32A of the casing string 32, and by coupling the fluid conduit to a pump discharge.
- an outlet of the fluid conduit such as a nozzle 35
- a fill up and circulation assembly 29 is disposed between the launcher assembly 6 and the gripping assembly 14.
- the fill up and circulation assembly 29 may be used for borehole cleaning and for placing the cement slurry in the targeted interval in the annulus.
- This process requires pressurization of the casing string 32 by disposing a seal 30 between the proximal end 46 of the casing string 32 and the fluid conduit that supplies fluid or cement slurry to the bore 32 A of the casing string 32. This enables the pump discharge to force fluid or cement slurry down the bore 32A of the casing string 32, out of the float collar (not shown) at the distal end not shown of the casing string 32) and back to the surface through the annulus.
- the seal 30 comprises an elastomeric circumferential packer cup seal that engages the internal wall of the casing string 32 upon sufficient insertion (as shown in Fig. 1) of the fill up and circulation assembly 29 into the proximal end 46 of the casing string 32.
- the launcher assembly is secured above the top drive for inserting the launching members (to launch wiper plugs from a wiper plug assembly) at a position upstream of the bore of the quill 5 of the top drive 3.
- the launcher assembly is secured atop the top drive.
- the launcher assembly 6 is disposed generally above and in fluid communication with a first inlet 42 to a "Y"-tube 41.
- the adjacent second inlet 43 is in fluid communication with a fluid pump (not shown) for providing a source of pressurized fluid down the bore 32A of casing string 32 via the bore of the quill 5 of the top drive 3.
- the launcher assembly selectively releases a launching member, such as a ball or dart, into the first inlet 42 to launch a first cement wiper plug 54 from the cement wiper plug assembly 57.
- the launching member Upon release of the launching member into the first inlet 42 of the "Y"-tube 41, the launching member descends through the drilling fluid due to the force of gravity, and may be accelerated in its descent to the first cement wiper plug 54 by the flow of fluid from the pumps (not shown) through hose 40 and into to the second inlet 43 of the "Y"-tube 41 and downwardly through the quill 5 and the bore of the gripping assembly 14 to the bore of the cement wiper plug assembly 57 that is coupled to the gripping assembly 14.
- the normal method of using the casing make-up and running tool of the present invention involves the steps of making up add-on casing segments into a casing string by gripping a casing segment with the gripping assembly 14, rotating the casing segment using the top drive 3 to threadably couple the add-on casing segment to the casing string suspended in the borehole, suspending the casing 32 from the gripping assembly 14 which is, in turn, coupled to and suspended from the top drive 3, lowering the casing string 32 into the borehole (not shown), transferring the weight of the casing string 32 to the spider (not shown) on the rig floor, using the top drive 3 and casing running tool 10 to pick up a new joint of casing, threadably connecting the new joint to the proximal end 46 of the casing string 32, filling the joint of casing with fluid, transferring the weight of the casing string 32 from the spider at the rig floor back to the top drive 3, and lowering the lengthened casing string 32 into the borehole.
- the process is repeated until the casing string achieves the desired length, and then a predetermined volume of cement slurry is mixed, circulated down the bore 32A of the casing string 32 and into the targeted interval of the annulus in generally the same manner used to circulate fluid.
- a check valve in the float assembly to prevent reverse flow back into the bore of casing string, the cement is held static in the targeted interval of the annulus until it sets.
- Cement placement in the annulus requires cooperation of the launcher assembly 6, fill up and circulation assembly 29, the cement wiper plug assembly (see element 57 of Figs. 1-4) and a float assembly (not shown) that is coupled to the distal end of the casing string 32 and run into the borehole at the bottom of the casing string 32.
- joints of casing are threadably made up, according to the method described above, and run into the borehole using the casing make up and running tool to create a casing string and to position the float assembly near the bottom of the targeted borehole interval.
- the float assembly generally comprises a biased valve that permits flow of fluid from the bore 32A of the casing string 32 into the annulus, while opposing reverse flow from the annulus into the bore 32 A of the casing string 32.
- the float assembly also comprises a plug landing receptacle disposed in alignment with the bore 32A of the casing string 32 and positioned to receive a cement wiper plug introduced into the bore at the surface and pumped through the bore to land on the float assembly.
- the cement wiper plug assembly 57 is coupled to the distal end of the gripping assembly 14.
- the cement wiper plug assembly 57 comprises a proximal of cement wiper plug 52 and a distal cement wiper plug 54, the latter releasably secured to the former in an aligned configuration, each having an internal bore for extending the fluid conduit into the bore 32 A of the casing string 32.
- This arrangement provides for unimpaired fluid circulation right up until the introduction of the cement slurry.
- the leading distal cement wiper plug 54 is launched ahead of the volume of cement slurry to prevent fouling of the cement slurry due to mixing with the fluid used to drill and circulate the borehole.
- a coupler 53 within the cement wiper plug assembly 57 couples to and extends the fluid conduit used to introduce fluid and cement slurry into the bore 32 A of the casing string 32.
- the cement wiper plugs 52, 54 are adapted to circumferentially engage and slide along the internal wall within the bore 32A of the casing string 32 after being inserted.
- Each cement wiper plug 52, 54, and coupler 53 that releasably secures the distal cement wiper plug 54 to the proximal cement wiper plug 52 has a bore 55 that extends the fluid conduit further into the bore 32A of the casing string 32 when the cement wiper plug assembly 57 is coupled to the distal end 14B of the fill up and circulation assembly 29.
- the cement wiper plug assembly 57 may also couple to the distal end of the fill up and circulation assembly 29 on embodiments of the present invention having external gripping assemblies for gripping and supporting the casing string, as shown in Fig. 3.
- the cement wiper plug assembly 57 is optimally secured to the casing make up and running assembly of the present invention just before picking up the last joint of casing to be made up into the casing string 32 in accordance with the method described above. This structure and method provides the significant benefit of preventing delay between borehole cleaning and the placement of cement, and results in cement liners having improved integrity.
- the bore 55 of the cement wiper plug assembly 57 (in Figs. 2-4) facilitates circulation of fluid for cleaning of the annulus right up to the introduction of cement slurry into the bore 32A of the casing string 32 for placement of cement slurry in the targeted interval.
- the launcher assembly 6 in Figs. 2-4 is used to control the deployment of the cement wiper plugs into the bore 32A of the casing string 32.
- the launched device may be a ball, but it should be clear that darts or other launching members may be substituted for balls without loss of function.
- two balls 42, 44 of different diameters are stored in the chamber 65 for being selectively launched into the bore 88 of the launcher sub 84.
- the seat 52A of the proximal (upper) cement wiper plug 52 (see Fig. 2) has a slightly larger bore than the seat 54A of the distal (lower) cement wiper plug 54 (see Figs. 2-4).
- each of the plugs is adapted for receiving and capturing its mating launching member to substantially seal the bore in that plug and to isolate the lower portion of the bore 32A of the casing string 32 from the pump discharge to pressurize the fluid conduit.
- the smaller launching member 44 is first captured in the seat 54A of the distal cement wiper plug 54 (see Figs. 2-4), and the larger launching member 42 is later captured in the seat 52A of the proximal cement wiper plug 52 (see Figs. 2-4).
- the distal cement wiper plug 54 is first deployed by release from the storage chamber 65 of the smaller launching member, in this case a ball 44, (see Fig. 5) into the passageway 86.
- the launched distal cement wiper plug 54 is followed into the bore 32A of the casing string 32 by the volume of cement slurry introduced through the cement adapter 66 .
- the larger launching member shown as a larger ball 42, is launched from the storage chamber 65 into the passageway 86 and into the fluid conduit, and received in the seat 52A of the proximal cement wiper plug 52 to substantially close the bore.
- Pressurization of the fluid conduit between the pump discharge and the seated launching member deploys the proximal cement wiper plug 52 into the bore 32A of the casing string 32 releasing the cement wiper plug at a predetermined force to separate the proximal cement wiper plug from the coupler 53.
- Each deployed cement wiper plug provides a moving barrier separating, for the distal cement wiper plug 54, the cement slurry behind the plug from the fluid ahead of the plug, and for the proximal cement wiper plug 52, the cement slurry ahead of the plug from the fluid behind the plug .
- the distal cement wiper plug 54 lands on the float collar at the distal end of the casing string 32, and the pump discharge pressure temporarily increases to open up the through bore in the distal cement wiper plug 54. Opening a through bore allows the cement slurry behind the distal cement wiper plug 54 to flow from the inside bore 32A of the casing string 32 into the annulus, and to be displaced by continued pumping back toward the surface to a predetermined level within the annulus.
- the proximal cement wiper plug 52 lands on the distal cement wiper plug 54 at the float collar at the distal end of the casing string to again temporarily isolate the bore 32A of the casing string 32 from the annulus. Pressurization of the fluid conduit against the proximal cement wiper plug 52 indicates that the plugs have "bumped.”
- the launcher assembly 6 shown in Fig. 5 may comprise one or more safety features to prevent inadvertent launching of the larger launching member 42 before the smaller launching member 52.
- the launcher assembly 6 facilitates the introduction of the selected launching member into the fluid conduit and to the seat in the bore of the targeted cement wiper plug.
- Cement slurry may be introduced into the bore 32 A of the casing string 32 in the same manner as the fluid, i.e. through the fluid hose 40, and the bore 5A of the quill 5 of the top drive.
- cement slurry is introduced directly into the bore 88 of the launcher sub 84 through the cement adapter 66 shown in Figs. 1, 2 and 4.
- the cement adapter 66 provides an alternate point of entry for cement slurry to prevent erosion damage to seals and other components exposed to the fluid conduit in the top drive 3.
- the cement adapter 66 may be disposed within or near the launcher assembly 6, as shown in Figs.
- a valve may be disposed within the fluid conduit formed by the bores of the quill 5 and the launcher sub 84 to prevent unwanted flow of pressurized cement slurry introduced into the cement adapter 66 from entering the top drive.
- Fig. 4 is an elevation view of an alternate embodiment of the casing make up and running tool of the present invention having an external gripping assembly 18.
- the quill 5 of the top drive (not shown) rotatably supports a lift collar 7 that, in turn, supports the external gripping assembly 18 through a pair of bails 8, and the top drive fluid conduit extends downwardly through the aligned bores of the quill 5, the launcher sub 84 and the fill up and circulation assembly 29.
- the fill up and circulation assembly 29 is adapted for receiving and supporting a cement wiper plug assembly 57 at its distal end in the same manner as described above in relation to Fig. 2.
- the bore 88 of the launcher sub 84 and the bore of the fill up and circulation assembly 29 are aligned with the bore 5A of the quill 5 to extend the fluid conduit from of the top drive 3 down into the bore 32 A of the casing string 32.
- the fill up and circulation assembly 29 comprises a packer cup 30 that extends radially outwardly from the outside circumference of the fill up and circulation assembly 29 to engage and seal against the inside wall of the casing string 32 when the packer cup is inserted into the proximal end 46 of the casing string 32.
- the fluid pumps may then be activated to pressurize the bore of the fill up and circulation tool.
- Additional assemblies and devices may be coupled into the casing make up and running tool to extend the fluid conduit or to manage and conserve fluid.
- the mud saver valve 31 generally comprises a valve that is biased closed and can be opened by pressure to permit flow from the bore of the fill up and circulation assembly 29 to the bore of the casing string at a predetermined differential pressure. The mud saver valve 31 prevents unwanted loss of fluid from the fluid conduit when the pump is inactive and the tool is pulled out of the proximal end of the casing.
- Gripping assembly includes, but is not limited to, an internal cage grip tool, an internal wedge grip tool, an external elevator having a generally circumferential internal shoulder for abutting and supporting an internally threaded sleeve received on a pipe, and an elevator having an arrangement of slips for engaging the outside surface of the casing, a side door elevator, an elevator comprising internal or external slips, and all other devices used for gripping and supporting a pipe string from above the spider that may be supported by a top drive or draw works.
