[0079] An end of a stinger assembly 34 is coupled to another end of the packer setting tool assembly 32. In an exemplary embodiment, the stinger assembly 34 may be, or may include elements, of one or more conventional devices for engaging a conventional packer, or equivalents thereof.
[0080] An end of a packer assembly 36 is coupled to another end of the stinger assembly 34. In an exemplary embodiment, the packer assembly 36 may be, or may include elements, of one or more conventional packers.
[0081] As illustrated in Fig. 1, in an exemplary embodiment, during operation of the system 10, an expandable wellbore casing 100 is coupled to and supported by the casing lock assembly 24 of the system. The system 10 is then positioned within a wellbore 102 that traverses a subterranean formation 104 and includes a preexisting wellbore casing 106.
[0082] As illustrated in Fig. 2, in an exemplary embodiment, the extension actuator assembly 26 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 downwardly in a direction 108 and out of an end of the expandable wellbore casing 100. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved to a position out of the end of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly and adjustable casing expansion cone assembly are then operated to increase the outside diameters of the expansion cone assemblies. In an exemplary embodiment, the increased outside diameter of the adjustable bell section expansion cone assembly 28 is greater than the increased outside diameter of the adjustable casing expansion cone assembly 30.
[0083] As illustrated in Fig. 3, in an exemplary embodiment, the ball gripper assembly 16 is then operated to engage and hold the position of the expandable tubular member 100 stationary relative to the tubular support member 12. The tension actuator assembly 18 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 upwardly in a direction 110 into and through the end of the expandable wellbore casing 100. As a result, the end of the expandable wellbore casing 100 is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 to form a bell section 112. In an exemplary embodiment, during the operation of the system 10 described above with reference to Fig. 3, the casing lock assembly 24 may or may not be coupled to the expandable wellbore casing 100.
27
[0084] In an exemplary embodiment, the length of the end of the expandable wellbore casing 100 that is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 is limited by the stroke length of the tension actuator assembly 18. In an exemplary embodiment, once the tension actuator assembly 18 completes a stroke, the ball gripper assembly 16 is operated to release the expandable tubular member 100, and the tubular support 12 is moved upwardly to permit the tension actuator assembly to be re-set. In this manner, the length of the bell section 112 can be further extended by continuing to stroke and then re-set the position of the tension actuator assembly 18. Note, that, during the upward movement of the tubular support 12 to re-set the position of the tension actuator assembly 18, the expandable tubular wellbore casing 100 is supported by the expansion surfaces of the adjustable bell section expansion cone assembly 28.
[0085] As illustrated in Fig. 4, in an exemplary embodiment, the casing lock assembly 24 is then operated to engage and maintain the position of the expandable wellbore casing 100 stationary relative to the tubular support 12. The adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, and packer assembly 36 are displaced downwardly into the bell section 112 in a direction 114 relative to the expandable wellbore casing 100 by operating the extension actuator 26 and/or by displacing the system 10 downwardly in the direction 114 relative to the expandable wellbore casing. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved downwardly in the direction 114 into the bell section 112 of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly is then operated to decrease the outside diameter of the adjustable bell section expansion cone assembly. In an exemplary embodiment, the decreased outside diameter of the adjustable bell section expansion cone assembly 28 is less than the increased outside diameter of the adjustable casing expansion cone assembly 30. In an exemplary embodiment, during the operation of the system illustrated and described above with reference to Fig. 4, the ball gripper 16 may or may not be operated to engage the expandable wellbore casing 100.
[0086] As illustrated in Fig. 5, in an exemplary embodiment, the casing lock assembly 24 is then disengaged from the expandable wellbore casing 100 and fluidic material 116 is then injected into the system 10 through the tubular support 12 to thereby pressurize an annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is created across the cup seal assembly 22 that causes the cup seal assembly to apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in
28
the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing.
[0087] In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the injection of the fluidic material 116 to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.
[0088] As illustrated in Fig. 6, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the packer assembly 36 is positioned within a portion of the expandable tubular member above the bell section 112. The packer assembly 36 may then be operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112.
[0089] In an exemplary embodiment, after the packer assembly 36 is operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112, a hardenable fluidic sealing material 122 may then be injected into the system 10 through the tubular support 12 and then out of the system through the packer assembly to thereby permit the annulus between the expandable wellbore casing and the wellbore 102 to be filled with the hardenable fluidic sealing material. The hardenable fluidic sealing material 122 may then be allowed to cure to form a fluid tight annulus between the expandable wellbore casing 100 and the wellbore 102, before, during, or after the completion of the radial expansion and plastic deformation of the expandable wellbore casing.
[0090] As illustrated in Fig. 7, in an exemplary embodiment, the fluidic material 116 is then re-injected into the system 10 through the tubular support 12 to thereby re-pressurize the annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is once again created across the cup seal assembly 22 that causes the cup seal assembly to once again apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing and disengaging the stinger assembly 34 from the packer assembly 36. In an exemplary embodiment, during this operational mode, the packer assembly 36 prevents the flow of fluidic materials out of the expandable wellbore casing 100. As a result, the pressurization of the annulus 118 is rapid and efficient thereby enhancing the operational efficiency of the subsequent radial expansion and plastic deformation of the expandable wellbore casing 100.
[0091] In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the re-injection of the fluidic material 116 to displace the adjustable casing
29
expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.
[0092] As illustrated in Fig. 8, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the adjustable casing expansion cone assembly 30 reaches the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106. At which point, the system 10 may radially expand the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 and the surrounding portion of the preexisting wellbore casing. Consequently, in an exemplary embodiment, during the radial expansion of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106, the tension actuator assembly 16 is also operated to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100 and the preexisting wellbore casing 106 during the radial expansion of the portion 124 of the expandable wellbore casing that overlaps with the preexisting wellbore casing.
[0093] As illustrated in Fig. 9, in an exemplary embodiment, the entire length of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is not radially expanded and plastically deformed. Rather, only part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is radially expanded and plastically deformed. The remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is then cut away by operating the casing cutter assembly 14.
[0094] As illustrated in Fig. 10, the remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 that is cut away by operating the casing cutter assembly 14 is then also carried out of the wellbore 102 using the casing cutter assembly.
[0095] Furthermore, in an exemplary embodiment, the inside diameter of the expandable wellbore casing 100 above the bell section 112 is equal to the inside diameter of the portion of the preexisting wellbore casing 106 that does not overlap with the expandable wellbore casing 100. As a result, a wellbore casing is constructed that includes overlapping wellbore casings that together define an internal passage having a constant cross-sectional area.

42
connection 11068a of an end of a tubular member 11068 that defines a longitudinal passage 11068b and mounting holes, 11068c and 11068d, and includes an external annular recess 11068e, and an external threaded connection 11068f at another end is received within and is coupled to the internal threaded connection 11066g of the tubular sleeve 11066.
[0117] Mounting screws, 11070a and 11070b, are mounted in and coupled to the mounting holes, 11068c and 11068d, respectively, of the tubular member 11068 that also extend into the mounting holes, 11066b and 11066c, respectively, of the tubular sleeve
11066. A sealing element 11072 is received within the external annular recess 11068e of the tubular member 11068 for sealing the interface between the tubular member and the tubular sleeve 11066.
[0118] An internal threaded connection 11074a of a tubular retracting piston 11074 that defines a longitudinal passage 11074b and includes an internal annular recess 11074c and an external annular recess 11074d receives and is coupled to the external threaded connection 11006i of the tubular lower mandrel 11006. A sealing element 11076 is received within the external annular recess 11074d of the tubular retracting piston 11074 for sealing the interface between the tubular retracting piston and the tubular sleeve 11066. A sealing element 11078 is received within the internal annular recess 11074c of the tubular retracting piston 11074 for sealing the interface between the tubular retracting piston and the tubular lower mandrel 11006.
[0119] Locking dogs 11080 mate with and receive the external teeth 11006h of the tubular lower mandrel 11006. A spacer ring 11082 is positioned between an end face of the locking dogs 11080 and an end face of the lower cam assembly 11060. A release piston
11084 mounted upon the tubular lower mandrel 11006 defines a radial passage 11084a for mounting a burst disk 11086 includes sealing elements, 11084b, 11084c, and 11084d. The sealing elements, 11084b and 11084d, sealing the interface between the release piston 11084 and the tubular lower mandrel 11006. An end face of the release piston 11084 is positioned in opposing relation to an end face of the locking dogs 11080.
[0120] A release sleeve 11088 that receives and is mounted upon the locking dogs 11080 and the release piston 11084 includes an internal flange 11088a at one end that sealingly engages the tubular lower mandrel 11006. A bypass sleeve 11090 that receives and is mounted upon the release sleeve 11088 includes an internal flange 11090a at one end.
[0121] In an exemplary embodiment, during operation of the casing cutter assembly 14, the retracting spring 11044 is compressed and thereby applies a biasing spring force in a direction 11092 from the lower tubular mandrel 11006 to the tubular spring housing 11034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 11052 and the upper casing cutter segments 11054 out of engagement with the lower casing cutter
43
segments 11058 and the lower cam assembly 11060. In an exemplary embodiment, during operation of the casing cutter assembly 14, an external threaded connection 12A1 to 12A4 of an end of the tubular support member 12 is coupled to the internal threaded connection 11002d of the upper tubular tool joint 11002 and an internal threaded connection 16a of an end of the ball gripper assembly 16 is coupled to the external threaded connection 11068f of the tubular member 11068.
[0122] The upper cam assembly 11052 and the upper casing cutter segments 11054 may be brought into engagement with the lower casing cutter segments 11058 and the lower cam assembly 11060 by pressurizing an annulus 11094 defined between the lower tubular mandrel 11006 and the tubular spring housing 11034. In particular, injection of fludic materials into the cam cutter assembly 14 through the longitudinal passage 11006b of the lower tubular mandrel 11006 and into the radial passage 11006ba may pressurize the annulus 11094 thereby creating sufficient operating pressure to generate a force in a direction 11096 sufficient to overcome the biasing force of the retracting spring 11044. As a result, the spring housing 11034 may be displaced in the direction 11096 relative to the lower tubular mandrel 11006 thereby displacing the tubular upper hinge sleeve 11050, upper cam assembly 11052 , and upper casing cutter segments 11054 in the direction 11096.
[0123] In an exemplary embodiment, as illustrated in Fig. 11L, the displacement of the upper cam assembly 11052 and upper casing cutter segments 11054 in the direction 11096 will cause the lower casing cutter segments 11058 to ride up the cam surfaces of the cam arms of the upper cam assembly 11052 while also pivoting about the lower tubular hinge segment 11064, and will also cause the upper casing cutter segments 11054 to ride up the cam surfaces of the cam arms of the lower cam assembly 11060 while also pivoting about the upper tubular hinge segment 11050.
[0124] In an exemplary embodiment, during the operation of the casing cutter assembly 14, when the upper and lower casing cutter segments, 11054 and 11058, brought into axial alignment in a radially expanded position, the casing cutter elements of the casing cutter segments are brought into intimate contact with the interior surface of a preeselected portion of the expandable wellbore casing 100. The casing cutter assembly 14 may then be rotated to thereby cause the casing cutter elements to cut through the expandable wellbore casing. The portion of the expandable wellbore casing 100 cut away from the remaining portion on the expandable wellbore casing may then be carried out of the wellbore 102 with the cut away portion of the expandable wellbore casing supported by the casing cutter elements.
[0125] In an exemplary embodiment, the upper cam assembly 11052 and the upper casing cutter segments 11054 may be moved out of engagement with the lower casing cutter segments 11058 and the lower cam assembly 11060 by reducing the operating pressure within the annulus 11094.
44
[0126] In an alternative embodiment, during operation of the casing cutter assembly 14, the upper cam assembly 11052 and the upper casing cutter segments 11054 may also be moved out of engagement with the lower casing cutter segments 11058 and the lower cam assembly 11060 by sensing the operating pressure within the longitudinal passage 11006b of the lower tubular mandrel 11006. In particular, if the operating pressure within the longitudinal passage 11006b of the lower tubular mandrel 11006 exceeds a predetermined value, the burst disc 11086 will open thereby pressurizing the interior of the tubular release sleeve 11088 thereby displacing the tubular release sleeve downwardly away from engagement with the locking dogs 11080. As a result, the locking dogs 11080 are released from engagement with the lower tubular mandrel 11006 thereby permitting the lower casing cutter segments 11058 and the lower cam assembly 11060 to be displaced downwardly relative to the lower tubular mandrel. The retracting piston 11074 may then be displaced downwardly by the operating pressure thereby impacting the internal flange 11066f of the lower tubular mandrel 11066. As a result, the lower tubular mandrel 11066, the lower casing cutter segments 11058, the lower cam assembly 11060, and tubular lower hinge sleeve 11064 are displaced downwardly relative to the tubular spring housing 11034 thereby moving the lower casing cutter segments 11058 and the lower cam assembly 11060 out of engagement with the upper cam assembly 11052 and the upper casing cutter segments 11054.
[0127] In an exemplary embodiment, during operation of the casing cutter assembly 14, the casing cutter assembly 14 senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 11022 and 11028, lower toggle links, 11024 and 11030, and triggers, 11026 and 11032, and then prevents the engagement of the upper cam assembly
11052 and the upper casing cutter segments 11054 with the lower casing cutter segments 11058 and the lower cam assembly 11060. In particular, anytime the upper toggle links, 11022 and 11028, and lower toggle links, 11024 and 11030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 11026 and 11032, will be maintained in a position in which the triggers will engage the internal flange 11034d of the end of the tubular spring housing 11034 thereby preventing the displacement of the tubular spring housing in the direction 11096. As a result, the upper cam assembly 11052 and the upper casing cutter segments 11054 cannot be brought into engagement with the lower casing cutter segments 11058 and the lower cam assembly 11060.
[0128] Conversely, anytime the upper toggle links, 11022 and 11028, and lower toggle links, 11024 and 11030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 11026 and 11032, will be pivoted by the engagement arms, 11024d and 11030d, of the
45
lower toggle links, 11024 and 11030, to a position in which the triggers will no longer engage the internal flange 11034d of the end of the tubular spring housing 11034 thereby permitting the displacement of the tubular spring housing in the direction 11096. As a result, the upper cam assembly 11052 and the upper casing cutter segments 11054 can be brought into engagement with the lower casing cutter segments 11058 and the lower cam assembly 11060.
[0129] In an alternative embodiment, the elements of the casing cutter assembly 14 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted.
[0130] In an exemplary embodiment, the ball gripper assembly 16 is provided and operates substantially, at least in part, as disclosed in one or more of the following: (1) PCT patent application serial number PCT/US03/29859, attorney docket no. 25791.102.02, filed on 9/22/2003, and/or (2) PCT patent application serial number PCT/US03/14153, attorney docket number 25791.104.02, filed on 11/13/2003, the disclosures of which are incorporated herein by reference.
[0131] In an exemplary embodiment, as illustrated in Figs. 12A1 to 12A4, 12B and 12C1 to 12C4, the ball gripper assembly 16 includes an upper mandrel 1202 that defines a longitudinal passage 1202a and a radial passage 1202b and includes an internal threaded connection 1202c at one end, an external flange 1202d at an intermediate portion that includes an external annular recess 1202e having a shoulder 1202f and an external radial hole 1202g, an external annular recess 1202h, an external annular recess 1202i, an external annular recess 1202j having a tapered end 1202k including an external annular recess 1202ka, an external annular recess 12021, and an external annular recess 1202m, and an external annular recess 1202n, an external radial hole 1202o, an external annular recess 1202p, and an external annular recess 1202q at another end.

A screw 1206 that is threadably coupled to the internally threaded radial opening 1204a of the upper tubular bushing 1204 extends into the external radial hole 1202g of the external flange 1202d of the upper mandrel 1202.
[0133] A deactivation tubular sleeve 1208 defines a radial passage 1208a and includes an internal annular recess 1208b that mates with and receives an end of the external annular recess 1204c of the external flange 1204b of the upper tubular bushing 1204, an internal annular recess 1208c that mates with and receives the external flange 1202d of the upper mandrel 1202, an internal annular recess 1208d, an internal annular recess 1208e,
46
and an internal annular recess 1208f. A deactivation spring 1210 is received within an annulus 1212 defined between the internal annular recess 1208b of the deactivation tubular sleeve 1208, an end face of the external annular recess 1204c of the external flange 1204b of the upper tubular bushing 1204, and the external annular recess 1202h of the external flange 1202d of the upper mandrel 1202.
[0134] A sealing member 1214 is received with the external annular recess 1202i of the external flange 1202d of the upper mandrel 1202 for sealing the interface between the upper mandrel and the deactivation tubular sleeve 1208. An annular spacer element 1216 is received within the external annular recess 1202ka of the tapered end 1202k of the external annular recess 1202j of the upper mandrel 1202.
[0135] One or more inner engagement elements 1218a of a tubular coglet 1218 engage and are received within the external annular recess 1202ka of the tapered end 1202k of the external annular recess 1202j of the upper mandrel 1202 and one or more outer engagement elements 1218b of the coglet engage and are received within the internal annular recess 1208d of the deactivation tubular sleeve 1208.
[0136] An external annular recess 1220a of an end of a tubular coglet prop 1220 that includes an inner flange 1220b receives and mates with the inner surfaces of the outer engagement elements 1218b of the coglet 1218. The end of the tubular coglet prop 1220 further receives and mates with the external annular recess 1202j of the external flange 1202d of the upper mandrel 1202. A sealing element 1222 is received within the external annular recess 12021 of the upper mandrel 1202 for sealing the interface between the upper mandrel and the tubular coglet prop 1220.
[0137] An end of a tubular bumper sleeve 1224 that includes internal and external flanges, 1224a and 1224b, and a hole 1224c at another end mates with and receives the external annular recess 1202m of the external flange 1202d of the upper mandrel 1202. A coglet spring 1226 is received within an annulus 1228 defined between the external annular recess 1202m of the external flange 1202d of the upper mandrel 1202, the tubular coglet prop 1220, the inner flange 1220b of the tubular coglet prop, an end face of the tubular bumper sleeve 1224, and the internal annular recess 1208c of the deactivation tubular sleeve 1208.
[0138] A tubular ball race 1228 that defines a plurality of tapered annular recesses 1228a and an internally threaded radial opening 1228b and includes one or more axial engagement elements 1228c at one end and one or more axial engagement elements

In an exemplary embodiment, the axial engagement elements 1228c of the tubular ball race 1228 are received within and are coupled to the hole 1224c of the tubular bumper sleeve 1224. An end of a tubular activation sleeve 1230 that defines a plurality of radial openings
47
1230a, a radial opening 1230b, a radial opening 1230c, and includes an internal annular recess 1230d receives and mates with the tubular ball race 1228. In an exemplary embodiment, an end face of an end of the tubular activation sleeve 1230 is positioned proximate and in opposing relation to an end face of an end of the deactivation sleeve 1208. In an exemplary embodiment, the radial openings 1230a are aligned with and positioned in opposing relation to corresponding of tapered annular recesses 1228a of the tubular ball race 1228, and the radial openings are also narrowed in cross section in the radial direction for reasons to be described.
[0139] Balls 1232 are received within each of the of tapered annular recesses 1228a and corresponding radial openings 1230a of the tubular ball race 1228 and tubular activation sleeve 1230, respectively. In an exemplary embodiment, the narrowed cross sections of the radial openings 1230a of the tubular activation sleeve 1230 will permit the balls 1232 to be displaced outwardly in the radial direction until at least a portion of the balls extends beyond the outer perimeter of the tubular activation sleeve to thereby permit engagement of the balls with an outer structure such as, for example, a wellbore casing.
[0140] A lower mandrel 1234 that defines a longitudinal passage 1234a and an internally threaded radial passage 1234b at one end and includes internal annular recesses, 1234c and 1234d, for receiving and mating with the external annular recesses, 1202p and 1202q, of the upper mandrel 1202, an internal annular recess 1234e, an external flange 1234f, and an externally threaded connection 1234g at another end. In an exemplary embodiment, as illustrated in Fig. 12B, the end of the lower mandrel 1234 further includes longitudinal recesses 1234h for receiving and mating with corresponding axial engagement elements 1228d of the tubular ball race 1228. A sealing element 1235 is received within the internal annular recess 1234d of the lower mandrel 1234 for sealing an interface between the lower mandrel and the external annular recess 1202p of the upper mandrel 1202.
[0141] A tubular spring retainer 1236 that defines a radial passage 1236a and includes an external annular recess 1236b at one end mates with and receives the end of the lower mandrel 1234 and is positioned proximate an end face of the external flange 1234f of the lower mandrel. A tubular spring retainer 1238 receives and mates with the end of the lower mandrel 1234 and is received and mates with the internal annular recess 1230d of the tubular activation sleeve 1230.
[0142] An activation spring 1240 is received within an annulus 1242 defined an end face of the tubular spring retainer 1238, an end face of the spring retainer 1236, the internal annular recess 1230d of the tubular activation sleeve 1230, and the end of the lower mandrel 1234. A retainer screw 1242 is received within and is threadably coupled to the internally threaded radial opening 1234b of the lower mandrel 1234 that also extends into the external radial hole 1202o of the upper mandrel 1202.
48
[0143] During operation of the ball gripper assembly 16, in an exemplary embodiment, as illustrated in Figs. 12A1 to 12A4, the ball gripper assembly may be positioned within the expandable wellbore casing 100 and the internally threaded connection 1202c of the upper mandrel 1202 may be coupled to an externally threaded connection 14a of an end of the casing cutter assembly 14 and the externally threaded connection 1234g of the lower mandrel 1234 may be coupled to an internally threaded connection 18a of an end of the tension actuator assembly 18.
[0144] In an alternative embodiment, the internally threaded connection 1202c of the upper mandrel 1202 may be coupled to an externally threaded connection of an end of the tension actuator assembly 18 and the externally threaded connection 1234g of the lower mandrel 1234 may be coupled to an internally threaded connection of an end of casing cutter assembly 14.
[0145] In an exemplary embodiment, the deactivation spring 1210 has a greater spring rate than the activation spring 1240. As a result, in an initial operating mode, as illustrated in Figs. 12A1 to 12A4, a biasing spring force is applied to the deactivation sleeve 1208 and activation sleeve 1230 in a direction 1244 that maintains the activation sleeve in a position relative to the tubular ball race 1228 that maintains the balls 1232 within the radially inward portions of the corresponding tapered annular recesses 1228a of the tubular ball race such that the balls do not extend beyond the perimeter of the activation sleeve to engage the expandable wellbore casing 100.
[0146] As illustrated in Figs. 12C1 to 12C4, in an exemplary embodiment, the ball gripper 16 may be operated to engage the interior surface of the expandable wellbore casing 100 by injecting a fluidic material 1250 into the ball gripper assembly through the longitudinal passages 1202a and 1234aa, of the upper and lower mandrels, 1202 and 1234,
respectively.
[0147] In particular, when the longitudinal and radial passages, 1202a and 1202b, respectively, of the upper mandrel 1202 are pressurized by the injection of the fluidic material 1250, the internal annular recess 1208c of the deactivation tubular sleeve 1208 is pressurized. When the operating pressure of the fluidic material 1250 within the internal annular recess 1208c of the deactivation tubular sleeve 1208 is sufficient to overcome the biasing spring force of the deactivation spring 1210, the deactivation tubular sleeve is displaced in a direction 1252. As a result, the spring force provided by the activation spring 1240 then may displace the activation tubular sleeve 1230 in the direction 1252 thereby moving the balls 1232 on the corresponding tapered annular recesses 1228a of the tubular ball race 1228 outwardly in a radial direction into engagement with the interior surface of the expandable wellbore casing 100. In an exemplary embodiment, the operating pressure of
49
the fluidic material 1250 sufficient to overcome the biasing spring force of the deactivation spring 1210 was about 100 psi.
[0148] In an exemplary embodiment, when the operating pressure of the fluidic material 1250 is reduced, the operating pressure of the fluidic material 1250 within the internal annular recess 1208c of the deactivation tubular sleeve 1208 is no longer sufficient to overcome the biasing spring force of the deactivation spring 1210, and the deactivation tubular sleeve and the activation tubular sleeve 1230 are displaced in a direction opposite to the direction 1252 thereby moving the balls 1232 radially inwardly and out of engagement with the interior surface of the expandable wellbore casing 100.
[0149] In an exemplary embodiment, the ball gripper assembly 16 is operated to engage the interior surface of the expandable wellbore casing 100 in combination with the operation of the tension actuator assembly 18 to apply an upward tensile force to one or more elements of the system 10 coupled to and positioned below the tension actuator assembly. As a result, a reaction force comprising a downward tensile force is applied to the lower mandrel 1234 of the ball gripper assembly 16 in a direction opposite to the direction 1252 during the operation of the tension actuator assembly 18. Consequently, due to the geometry of the tapered 1228a of the tubular ball race 1228, the balls 1232 are driven up the tapered annular recesses 1228a of the tubular ball race 1228 with increased force and the contact force between the balls 1232 and the interior surface of the expandable wellbore casing 100 is significantly increased thereby correspondingly increasing the gripping force and effect of the ball gripper assembly.
[0150] In an exemplary embodiment, the ball gripper assembly 16 may be operated to radially expand and plastically deform discrete portions of the expandable wellbore casing 100 by controlling the amount of contact force applied to the interior surface of the expandable wellbore casing by the balls 1232 of the ball gripper assembly. In an experimental test of an exemplary embodiment of the ball gripper assembly 16, an expandable wellbore casing was radially expanded and plastically deformed. This was an unexpected result.
[0151] In an exemplary embodiment, the tension actuator assembly 18 operates and is provided substantially, at least in part, as disclosed in one or more of the following: (1) PCT patent application serial number PCT/US02/36267, attorney docket number 25791.88.02, filed on 11/12/2002, (2) PCT patent application serial number PCT/US03/29859, attorney docket no. 25791.102.02, filed on 9/22/2003, (3) PCT patent application serial number PCT/US03/14153, attorney docket number 25791.104.02, filed on 11/13/2003, and/or (4) PCT patent application serial number PCT/US03/29460, attorney docket number 25791.114.02, filed on 9/23/2003, the disclosures of which are incorporated herein by reference.

[0171] In an exemplary embodiment, as illustrated in Figs. 13A1 to 13A8, the internally threaded connection 13002e of the upper tubular support member 13002 receives and is coupled to the externally threaded connection 1234g of the lower mandrel 1234 of the ball grabber assembly 16 and the externally threaded connection 13116h of the connector tube 13116 is received within and is coupled to an internally threaded connection 20a of an end of the safety sub assembly 20.
[0172] In an exemplary embodiment, as illustrated in Figs. 13A1 to 13A8, during operation of the tension actuator assembly 18, the tension actuator assembly is positioned within the expandable wellbore casing 100 and fluidic material 13200 is injected into the tension actuator assembly through the passages 13002a, 13016a, 13066a, 13070a, 13076a, 13080a, 13086a, 13090a, 13096a, 13100a, 13106a, 13110a, and 13116a. The injected fluidic material 13200 will also pass through the radial passages, 13070d and 13070e,
13080d and 13080e, 13090d and 13090e, 13100d and 13100e, 13110d and 13110e, of the tubular pistons, 13070,13080, 13090, 13100, and 13110, respectively, into annular piston chambers, 13202, 13204, 13206, 13208, 13208, and 13210.
[0173] As illustrated in Figs. 13B1 to 13B7, the operating pressure of the fluidic material 13200 may then be increased by, for example, controllably blocking or limiting the flow of the fluidic material through the passage 13116a and/or increasing the operating pressure of the outlet of a pumping device for injecting the fluidic material 13200 into the tension actuator assembly 18. As a result, of the increased operating pressure of the fluidic material 13200 within the tension actuator assembly 18, the operating pressures of the annular piston chambers, 13202, 13204, 13206, 13208, 13208, and 13210, will be increased sufficiently to displace the tubular pistons, 13070, 13080, 13090, 13100, and 13110, upwardly in the direction 13212 thereby also displacing the connector tube 13116. As a result, a upward tensile force is applied to all elements of the system 10 coupled to and positioned below the connector tube 13116. In an exemplary embodiment, during the upward displacement of the tubular pistons, 13070, 13080, 13090, 13100, and 13110, fluidic materials displaced by the tubular pistons within discharge annular chambers, 13214, 13216, 13218, 13220, and 13222 are exhausted out of the tension actuator assembly 18 through the radial passages, 13008d and 13008e, 13022d and 13022e, I3030d and 13030e, 13040d and 13040e, 13050d and 13050e, respectively. Furthermore, in an exemplary embodiment, the upward displacement of the tubular pistons, 13070, 13080,13090, 13100, and 13110, further causes the external splines 13066d of the connector tube 13066 to engage the internal splines 13014b of the tubular member 13014 and the circumferentially spaced apart teeth 13116g of the connector

[0206] An external threaded connection 1594a of a baffle nose 1594 that defines longitudinal passages, 1594b and 1594c, is received within and is coupled to the internal threaded connection internal threaded connection 1588d of the composite nose 1588.
[0207] In an exemplary embodiment, as illustrated in Figs. 16A1 to 16A5, during the operation of the packer setting tool assembly 32 and packer assembly 36, the packer setting tool and packer assembly are coupled to one another by inserting the end of the tubular upper adaptor 1502 into the other end of the tubular coupling ring 1444, bringing the circumferentially spaced teeth 1416g of the other end of the tubular bushing 1416 into engagement with the circumferentially spaced teeth 1502e of the end of the tubular upper adaptor, and mounting shear pins, 1602a and 1602b, within the mounting holes, 1444c and 1502c, and, 1444d and 1502d, respectively, of the tubular coupling ring and tubular upper adaptor, respectively. As a result, the tubular mandrel 1406 and tubular stinger 1408 of the packer setting tool assembly 32 are thereby positioned within the longitudinal passage 1504a of the tubular upper mandrel 1504 with the 1408e of the tubular stinger positioned within the longitudinal passage 1546b of the tubular lower mandrel 1546 proximate the collet fingers 1550d of the tubular sliding sleeve valve 1550.
[0208] Furthermore, in an exemplary embodiment, during the operation of the packer setting tool 32 and packer assembly 36, as illustrated in Figs. 16A1 to 16A5, the packer setting tool and packer assembly are positioned within the expandable wellbore casing 100 and an internal threaded connection 30a of an end of the adjustable casing expansion cone assembly 30 receives and is coupled to the external threaded connection 1402f of the end of the tubular adaptor 1402 of the packer setting tool assembly. Furthermore, shear pins, 1604a and 1604b, mounted within the mounting holes, 1558b and 1558c, of the tubular outer sleeve 1558 couple the tubular outer sleeve to the expandable wellbore casing. As a result, torsion loads may transferred between the tubular outer sleeve 1558 and the expandable wellbore casing 100.
[0209] In an exemplary embodiment, as illustrated in Figs. 16B1 to 16B5, a conventional plug 1606 is then injected into the setting tool assembly 32 and packer assembly 36 by
67
injecting a fluidic material 1608 into the setting tool assembly and packer assembly through the longitudinal passages, 1402a, 1404b, 1406b, 1408b, 1550a, 1546a, 1560b, and 1564a of the tubular adaptor 1402, tubular upper mandrel 1404, tubular mandrel 1406, tubular stinger 1408, tubular sliding sleeve valve 1550, tubular lower mandrel 1546, tubular bypass mandrel 1560, and tubular plug seat 1564, respectively. The plug 1606 is thereby positioned within the longitudinal passage 1564a of the tubular plug seat 1564. Continued injection of the fluidic material 1608 following the seating of the plug 1606 within the longitudinal passage 1564a of the tubular plug seat 1564 causes the plug and the tubular plug seat to be displaced downwardly in a direction 1610 until further movement of the tubular plug seat is prevented by interaction of the set screw 1574 with the external annular recess 1564f of the tubular plug seat. As a result, the flow ports, 1564c and 1564d, of the tubular plug seat 1564 are moved out of alignment with the upper flow ports, 1560c and 1560d, of the tubular bypass mandrel 1560.
[0210] In an exemplary embodiment, as illustrated in Figs. 16C1 to 16C5, after the expandable wellbore casing 100 has been radially expanded and plastically deformed to form at least the bell section 112 of the expandable wellbore casing 100 thereby shearing the shear pins, 1604a and 1604b, the setting tool assembly 32 and packer assembly 36 are then moved upwardly to a position within the expandable wellbore casing 100 above the bell section. The tubular adaptor 1402 is then rotated, by rotating the tool string of the system 10 above the setting tool assembly 32, to displace and position the drag blocks, 1428 and 1430, into engagement with the interior surface of the expandable wellbore casing 100.
[0211] As a result of the engagement of the drag blocks, 1428 and 1430, with the interior surface of the expandable wellbore casing 100, further rotation of the drag blocks relative to the wellbore casing is prevented. Consequently, due to the operation and interaction of the threaded connections, 1416d and 1418a, of the tubular bushing 1416 and tubular drag block body 1418, respectively, further rotation of the tubular adaptor 1402 causes the tubular drag block body and setting sleeve 1442 to be displaced downwardly in a direction 1612 relative to the remaining elements of the setting tool assembly 32 and packer assembly 36. As a result, the setting sleeve 1442 engages and displaces the upper tubular spacer ring 1506 thereby shearing the shear pins, 1522a and 1522b, and driving the upper tubular slip 1512 onto and up the angled end face 1520d of the upper tubular wedge 1520 and into engagement with the interior surface of the expandable wellbore casing 100. As a result, longitudinal displacement of the upper tubular slip 1512 relative to the expandable wellbore casing 100 is prevented. Furthermore, as a result, the 1446b collet fingers of the tubular retaining collet 1446 are disengaged from the tubular upper adaptor 1502.
[0212] In an alternative embodiment, after the drag blocks, 1428 and 1430, engage the interior surface of the expandable wellbore casing 100, an upward tensile force is applied to
68
the tubular support member 12, and the ball gripper assembly 16 is then operate to engage the interior surface of the expandable wellbore casing. The tension actuator assembly 18 is then operated to apply an upward tensile force to the tubular adaptor 1402 thereby pulling the upper tubular spacer ring 1506, lower tubular spacer ring 1510, upper tubular slip 1512, lower tubular slip 1516, upper tubular wedge 1520, lower tubular wedge 1524, upper tubular extrusion limiter 1528, lower tubular extrusion limiter 1534, and central tubular elastomeric element 1544 upwardly into contact with the 1442 thereby compressing the upper tubular spacer ring, lower tubular spacer ring, upper tubular slip, lower tubular slip, upper tubular wedge, lower tubular wedge, upper tubular extrusion limiter, lower tubular extrusion limiter, and central tubular elastomeric element. As a result, the upper tubular slip 1512, lower tubular slip 1516, and central tubular elastomeric element 1544 engage the interior surface of the expandable wellbore casing 100.
[0213] In an exemplary embodiment, as illustrated in Figs. 16D1 to 16D5, an upward tensile force is then applied to the tubular adaptor 1402 thereby compressing the lower tubular slip 1516, lower tubular wedge 1524, central elastomeric packer element 1544, upper tubular extrusion limiter 1528, and upper tubular wedge 1520 between the lower tubular spacer ring 1510 and the stationary upper tubular slip 1512. As a result, the lower tubular slip 1516 is driven onto and up the angled end face 1524d of the lower tubular wedge 1524 and into engagement with the interior surface of the expandable wellbore casing 100, and the central elastomeric packer element 1544 is compressed radially outwardly into engagement with the interior surface of the expandable tubular member. As a result, further longitudinal displacement of the upper tubular slip 1512, lower tubular slip 1516, and central elastomeric packer element 1544 relative to the expandable wellbore casing 100 is prevented.
[0214] In an exemplary embodiment, as illustrated in Figs. 16E1 to 16E6, continued application of the upward tensile force to tubular adaptor 1402 will then shear the shear pins, 1602a and 1602b, thereby disengaging the setting tool assembly 32 from the packer assembly 36.
[0215] In an exemplary embodiment, as illustrated in Figs. 16F1 to 16F6, with the drag blocks, 1428 and 1430, in engagement with the interior surface of the expandable wellbore casing 100, the tubular adaptor 102 is further rotated thereby causing the tubular drag block body 1418 and setting sleeve 1442 to be displaced further downwardly in the direction 1612 until the tubular drag block body and setting sleeve are disengaged from the tubular stinger 1408. As a result, the tubular stinger 1408 of the setting tool assembly 32 may then be displaced downwardly into complete engagement with the tubular sliding sleeve valve 1550.
[0216] In an exemplary embodiment, as illustrated in Figs. 16G1 to 16G6, a fluidic material 1614 is then injected into the setting tool assembly 32 and the packer assembly 36
69
through the longitudinal passages 1402a, 1404b, 1406b, 1408b, 1504b, 1550a, and 1546b of the tubular adaptor 1402, tubular upper mandrel 1404, tubular mandrel 1406, tubular stinger 1408, tubular upper mandrel 1504, tubular sliding sleeve valve 1550, and tubular lower mandrel 1546, respectively. Because, the plug 1606 is seated within and blocks the longitudinal passage 1564a of the tubular plug seat 1564, the longitudinal passages 1504b, 1550a, and 1546b of the tubular upper mandrel 1504, tubular sliding sleeve valve 1550, and tubular lower mandrel 1546 are pressurized thereby displacing the tubular upper adaptor 1502 and tubular upper mandrel 1504 downwardly until the end face of the tubular upper mandrel impacts the end face of the upper tubular spacer ring 1506.
[0217] In an exemplary embodiment, as illustrated in Figs. 16H1 to 16H5, the setting tool assembly 32 is brought back into engagement with the packer assembly 36 until the engagement shoulder 1408e of the other end of the tubular stinger 1408 engages the collet fingers 1550d of the end of the tubular sliding sleeve valve 1550. As a result, further downward displacement of the tubular stinger 1408 displaces the tubular sliding sleeve valve 1550 downwardly until the radial flow ports, 1550b and 1550c, of the tubular sliding sleeve valve are aligned with the flow ports, 1546e and 1546f, of the tubular lower mandrel 1546. A hardenable fluidic sealing material 1616 may then be injected into the setting tool assembly 32 and the packer assembly 36 through the longitudinal passages 1402a, 1404b, 1406b, 1408b, and 1550a of the tubular adaptor 1402, tubular upper mandrel 1404, tubular mandrel 1406, tubular stinger 1408, and tubular sliding sleeve valve 1550, respectively. The hardenable fluidic sealing material may then flow out of the packer assembly 36 through the upper flow ports, 1558d and 1558e, into the annulus between the expandable wellbore casing 100 and the wellbore 102.
[0218] The tubular sliding sleeve valve 1550 may then be returned to its original position, with the radial flow ports, 1550b and 1550c, of the tubular sliding sleeve valve out of alignment with the flow ports, 1546e and 1546f, of the tubular lower mandrel 1546. The hardenable fluidic sealing material 1616 may then be allowed to cure before, during, or after the continued operation of the system 10 to further radially expand and plastically deform the expandable wellbore casing.
[0219] In an exemplary embodiment, the system 10 is provided as illustrated in Appendix A to the present application. Figs. 1-10, 11, 11a, 11b, 11c, 11 d, 11e, 11f, 11g, 11h, 11k, 111, 12a, 12b, 12c, 13a, 13b, 14, 15,16a, 16b, 16c, 16d, 16e, 16f, 16g, and 16h of appendix A generally correspond to Figs. 1-10, 11-1 to 11-2, 11A1 to 11A2, 11B1 to 11B2, 11C, 11D, 11E, 11F, 11G, 11H, 111, 11 J, 11K, 11L, 12A1 to 12A4, 12B, 12C1 to 12C4, 13A1 to 13A8, 13B1 to 13B7, 14Ato 14C, 15-1 to 15-5, 16A1 to 16A5, 16B1 to 16B5, 16C1 to 16C5, 16D1 to 16D5, 16E1 to 16E6, 16F1 to 16F6, 16G1 to 16G6, and 16H1 to 16H5, respectively.
