As a result, the tubular sleeve 3418 may be maintained in circumferential tension and the end portions, 3416 and 3430 , of the first and second tubular members, 3410 and 3432 , may be maintained in circumferential compression.
- Sleeve 3416 increases the axial compression loading of the connection between tubular members 3410 and 3432 before and after expansion by the expansion device.
- the sleeve 3418 may be secured to tubular members 3410 and 3432 , for example, by a heat shrink fit.
- the grooves 3414 and/or 3434 and/or the openings 3426 provide stress concentrations that in turn apply added stress forces to the mating threads of the threaded connections, 3412 and 3428 .
- the mating threads of the threaded connections, 3412 and 3428 are maintained in metal to metal contact thereby providing a fluid and gas tight connection.
- the orientations of the grooves 3414 and/or 3434 and the openings 3426 are orthogonal to one another.
- the grooves 3414 and/or 3434 are helical grooves.
- first and second tubular members, 3410 and 3432 are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.
- tubular sleeve 3418 during (a) the coupling of the first tubular member 3410 to the second tubular member 3432 , (b) the placement of the first and second tubular members in the structure, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits.
- the tubular sleeve 3418 protects the exterior surfaces of the end portions, 3416 and 3430 , of the first and second tubular members, 3410 and 3432 , during handling and insertion of the tubular members within the structure.
- tubular sleeve 3418 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 3432 to the first tubular member 3410 . In this manner, misalignment that could result in damage to the threaded connections, 3412 and 3428 , of the first and second tubular members, 3410 and 3432 , may be avoided.
- the tubular sleeve 3416 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 3418 can be easily rotated, that would indicate that the first and second tubular members, 3410 and 3432 , are not fully threadably coupled and in intimate contact with the internal flange 3420 of the tubular sleeve. Furthermore, the tubular sleeve 3418 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432 .
- the tubular sleeve 3418 may provide a fluid and gas tight metal-to-metal seal between interior surface of the tubular sleeve 3418 and the exterior surfaces of the end portions, 3416 and 3430 , of the first and second tubular members.
- tubular sleeve 3418 may be maintained in circumferential tension and the end portions, 3416 and 3430 , of the first and second tubular members, 3410 and 3432 , may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve.

FIG. 22 in an exemplary embodiment, afirst tubular member 2210 includes an internally threadedconnection 2212 at anend portion 2214. A first end of atubular sleeve 2216 that includes aninternal flange 2218 having a taperedportion 2220, and a second end that includes a taperedportion 2222, is then mounted upon and receives theend portion 2214 of thefirst tubular member 2210. In an exemplary embodiment, theend portion 2214 of thefirst tubular member 2210 abuts one side of theinternal flange 2218 of thetubular sleeve 2216, and the internal diameter of theinternal flange 2218 of thetubular sleeve 2216 is substantially equal to or greater than the maximum internal diameter of the internally threadedconnection 2212 of theend portion 2214 of thefirst tubular member 2210. An externally threadedconnection 2224 of anend portion 2226 of asecond tubular member 2228 having anannular recess 2230 is then positioned within thetubular sleeve 2216 and threadably coupled to the internally threadedconnection 2212 of theend portion 2214 of thefirst tubular member 2210. In an exemplary embodiment, theinternal flange 2218 of thetubular sleeve 2216 mates with and is received within theannular recess 2230 of theend portion 2226 of thesecond tubular member 2228. Thus, thetubular sleeve 2216 is coupled to and surrounds the external surfaces of the first and second tubular members, 2210 and 2228. - The internally threaded
connection 2212 of theend portion 2214 of thefirst tubular member 2210 is a box connection, and the externally threadedconnection 2224 of theend portion 2226 of thesecond tubular member 2228 is a pin connection. In an exemplary embodiment, the internal diameter of thetubular sleeve 2216 is at least approximately 0.020″ greater than the outside diameters of the first and second tubular members, 2210 and 2228. In this manner, during the threaded coupling of the first and second tubular members, 2210 and 2228, fluidic materials within the first and second tubular members may be vented from the tubular members. - As illustrated in
FIG. 22 , the first and second tubular members, 2210 and 2228, and thetubular sleeve 2216 may be positioned within anotherstructure 2232 such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating aconventional expansion device 2234 within and/or through the interiors of the first and second tubular members. The tapered portions, 2220 and 2222, of thetubular sleeve 2216 facilitate the insertion and movement of the first and second tubular members within and through thestructure 2232, and the movement of theexpansion device 2234 through the interiors of the first and second tubular members, 2210 and 2228, may be, for example, from top to bottom or from bottom to top. - During the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, the
tubular sleeve 2216 is also radially expanded and plastically deformed. As a result, thetubular sleeve 2216 may be maintained in circumferential tension and the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, may be maintained in circumferential compression. -
Sleeve 2216 increases the axial compression loading of the connection betweentubular members expansion device 2234.Sleeve 2216 may, for example, be secured totubular members - In several alternative embodiments, the first and second tubular members, 2210 and 2228, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.
- The use of the
tubular sleeve 2216 during (a) the coupling of thefirst tubular member 2210 to thesecond tubular member 2228, (b) the placement of the first and second tubular members in thestructure 2232, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, thetubular sleeve 2216 protects the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, during handling and insertion of the tubular members within thestructure 2232. In this manner, damage to the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, thetubular sleeve 2216 provides an alignment guide that facilitates the insertion and threaded coupling of thesecond tubular member 2228 to thefirst tubular member 2210. In this manner, misalignment that could result in damage to the threaded connections, 2212 and 2224, of the first and second tubular members, 2210 and 2228, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, thetubular sleeve 2216 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if thetubular sleeve 2216 can be easily rotated, that would indicate that the first and second tubular members, 2210 and 2228, are not fully threadably coupled and in intimate contact with theinternal flange 2218 of the tubular sleeve. Furthermore, thetubular sleeve 2216 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 2214 and 2226, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, thetubular sleeve 2216 may provide a fluid tight metal-to-metal seal between interior surface of thetubular sleeve 2216 and the exterior surfaces of the end portions, 2214 and 2226, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 2212 and 2224, of the first and second tubular members, 2210 and 2228, into the annulus between the first and second tubular members and thestructure 2232. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, thetubular sleeve 2216 may be maintained in circumferential tension and the end portions, 2214 and 2226, of the first and second tubular members, 2210 and 2228, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve. - In several exemplary embodiments, one or more portions of the first and second tubular members, 2210 and 2228, and the
tubular sleeve 2216 have one or more of the material properties of one or more of thetubular members - Referring to

FIG. 33 , in an exemplary embodiment, afirst tubular member 3310 includes an internally threadedconnection 3312 and anannular projection 3314 at anend portion 3316. - A first end of a
tubular sleeve 3318 that includes aninternal flange 3320 having a taperedportion 3322 and anannular recess 3324 for receiving theannular projection 3314 of thefirst tubular member 3310, and a second end that includes a taperedportion 3326, is then mounted upon and receives theend portion 3316 of thefirst tubular member 3310. - In an exemplary embodiment, the
end portion 3316 of thefirst tubular member 3310 abuts one side of theinternal flange 3320 of thetubular sleeve 3318 and theannular projection 3314 of the end portion of the first tubular member mates with and is received within theannular recess 3324 of the internal flange of the tubular sleeve, and the internal diameter of theinternal flange 3320 of thetubular sleeve 3318 is substantially equal to or greater than the maximum internal diameter of the internally threadedconnection 3312 of theend portion 3316 of thefirst tubular member 3310. An externally threadedconnection 3326 of anend portion 3328 of asecond tubular member 3330 having anannular recess 3332 is then positioned within thetubular sleeve 3318 and threadably coupled to the internally threadedconnection 3312 of theend portion 3316 of thefirst tubular member 3310. In an exemplary embodiment, theinternal flange 3332 of thetubular sleeve 3318 mates with and is received within theannular recess 3332 of theend portion 3328 of thesecond tubular member 3330. Thus, thetubular sleeve 3318 is coupled to and surrounds the external surfaces of the first and second tubular members, 3310 and 3328. - The internally threaded
connection 3312 of theend portion 3316 of thefirst tubular member 3310 is a box connection, and the externally threadedconnection 3326 of theend portion 3328 of thesecond tubular member 3330 is a pin connection. In an exemplary embodiment, the internal diameter of thetubular sleeve 3318 is at least approximately 0.020″ greater than the outside diameters of the first and second tubular members, 3310 and 3330. In this manner, during the threaded coupling of the first and second tubular members, 3310 and 3330, fluidic materials within the first and second tubular members may be vented from the tubular members. - As illustrated in
FIG. 33 , the first and second tubular members, 3310 and 3330, and thetubular sleeve 3318 may be positioned within anotherstructure 3334 such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating aconventional expansion device 3336 within and/or through the interiors of the first and second tubular members. The tapered portions, 3322 and 3326, of thetubular sleeve 3318 facilitate the insertion and movement of the first and second tubular members within and through thestructure 3334, and the movement of theexpansion device 3336 through the interiors of the first and second tubular members, 3310 and 3330, may, for example, be from top to bottom or from bottom to top. - During the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, the
tubular sleeve 3318 is also radially expanded and plastically deformed. As a result, thetubular sleeve 3318 may be maintained in circumferential tension and the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, may be maintained in circumferential compression. -
Sleeve 3316 increases the axial compression loading of the connection betweentubular members expansion device 3336.Sleeve 3316 may be secured totubular members - In several alternative embodiments, the first and second tubular members, 3310 and 3330, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.
- The use of the
tubular sleeve 3318 during (a) the coupling of thefirst tubular member 3310 to thesecond tubular member 3330, (b) the placement of the first and second tubular members in thestructure 3334, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, thetubular sleeve 3318 protects the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, during handling and insertion of the tubular members within thestructure 3334. In this manner, damage to the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, thetubular sleeve 3318 provides an alignment guide that facilitates the insertion and threaded coupling of thesecond tubular member 3330 to thefirst tubular member 3310. In this manner, misalignment that could result in damage to the threaded connections, 3312 and 3326, of the first and second tubular members, 3310 and 3330, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, thetubular sleeve 3318 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if thetubular sleeve 3318 can be easily rotated, that would indicate that the first and second tubular members, 3310 and 3330, are not fully threadably coupled and in intimate contact with theinternal flange 3320 of the tubular sleeve. Furthermore, thetubular sleeve 3318 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 3316 and 3328, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, thetubular sleeve 3318 may provide a fluid tight metal-to-metal seal between interior surface of thetubular sleeve 3318 and the exterior surfaces of the end portions, 3316 and 3328, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 3312 and 3326, of the first and second tubular members, 3310 and 3330, into the annulus between the first and second tubular members and thestructure 3334. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, thetubular sleeve 3318 may be maintained in circumferential tension and the end portions, 3316 and 3328, of the first and second tubular members, 3310 and 3330, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve. - In several exemplary embodiments, one or more portions of the first and second tubular members, 3310 and 3330, and the
sleeve 3318 have one or more of the material properties of one or more of thetubular members - Referring to
FIGS. 34 a, 34 b, and 34 c, in an exemplary embodiment, afirst tubular member 3410 includes an internally threaded connection 1312 and one or moreexternal grooves 3414 at anend portion 3416. - A first end of a
tubular sleeve 3418 that includes aninternal flange 3420 and a taperedportion 3422, a second end that includes a taperedportion 3424, and an intermediate portion that includes one or more longitudinally alignedopenings 3426, is then mounted upon and receives theend portion 3416 of thefirst tubular member 3410. - In an exemplary embodiment, the
end portion 3416 of thefirst tubular member 3410 abuts one side of theinternal flange 3420 of thetubular sleeve 3418, and the internal diameter of theinternal flange 3420 of thetubular sleeve 3416 is substantially equal to or greater than the maximum internal diameter of the internally threadedconnection 3412 of theend portion 3416 of thefirst tubular member 3410. An externally threadedconnection 3428 of anend portion 3430 of asecond tubular member 3432 that includes one or moreinternal grooves 3434 is then positioned within thetubular sleeve 3418 and threadably coupled to the internally threadedconnection 3412 of theend portion 3416 of thefirst tubular member 3410. In an exemplary embodiment, theinternal flange 3420 of thetubular sleeve 3418 mates with and is received within anannular recess 3436 defined in theend portion 3430 of thesecond tubular member 3432. Thus, thetubular sleeve 3418 is coupled to and surrounds the external surfaces of the first and second tubular members, 3410 and 3432. - The first and second tubular members, 3410 and 3432, and the
tubular sleeve 3418 may be positioned within another structure such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device within and/or through the interiors of the first and second tubular members. The tapered portions, 3422 and 3424, of thetubular sleeve 3418 facilitate the insertion and movement of the first and second tubular members within and through the structure, and the movement of the expansion device through the interiors of the first and second tubular members, 3410 and 3432, may be from top to bottom or from bottom to top. - During the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the
tubular sleeve 3418 is also radially expanded and plastically deformed. As a result, thetubular sleeve 3418 may be maintained in circumferential tension and the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, may be maintained in circumferential compression. -
Sleeve 3416 increases the axial compression loading of the connection betweentubular members sleeve 3418 may be secured totubular members - During the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the
grooves 3414 and/or 3434 and/or theopenings 3426 provide stress concentrations that in turn apply added stress forces to the mating threads of the threaded connections, 3412 and 3428. As a result, during and after the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, the mating threads of the threaded connections, 3412 and 3428, are maintained in metal to metal contact thereby providing a fluid and gas tight connection. In an exemplary embodiment, the orientations of thegrooves 3414 and/or 3434 and theopenings 3426 are orthogonal to one another. In an exemplary embodiment, thegrooves 3414 and/or 3434 are helical grooves. - In several alternative embodiments, the first and second tubular members, 3410 and 3432, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.

For example, thetubular sleeve 3418 protects the exterior surfaces of the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, during handling and insertion of the tubular members within the structure.

Furthermore, thetubular sleeve 3418 provides an alignment guide that facilitates the insertion and threaded coupling of thesecond tubular member 3432 to thefirst tubular member 3410. In this manner, misalignment that could result in damage to the threaded connections, 3412 and 3428, of the first and second tubular members, 3410 and 3432, may be avoided.

The theoretical collapse strength of a tubular member having a 9⅝ inch outside diameter and an approximately 0.9 inch wall thickness, which is the combined thickness of thetubular member 4402 a and thepreexisting structure 4406 b, was calculated to be approximately 16850 psi using API Collapse modeling.
