As illustrated in Fig. 1b, a first end of a tubular sleeve 16 12 012849 that includes an internai flange 18 and tapered portions, 20 and 22, at opposite ends is thenmounted upon and receives the end portion 14 of the first tubular member 10. In anexemplary embodiment, the end portion 14 of the first tubular member 10 abuts one side ofthe internai flange 18 of the tubular sleeve 16, and the internai diameter of the internai flangeof the tubular sleeve is substantially equal to or greater than the maximum internai diameterof the internally threaded connection 12 of the end portion of the first tubular member. Asillustrated in Fig. 1c, an externally threaded connection 24 of an end portion 26 of a secondtubular member 28 having an annular recess 30 is then positioned within the tubular sleeve16 and threadably coupled to the internally threaded connection 12 of the end portion 14 ofthe first tubular member 10. In an exemplary embodiment, the internai flange 18 of thetubular sleeve 16 mates with and is received within the annular recess 30 of the end portion26 of the second tubular member 28. Thus, the tubular sleeve 16 is coupled to andsurrounds the external surfaces of the first and second tubular members, 10 and 28.

[0097] In an exemplary embodiment, the internally threaded connection 12 of the end portion14 of the first tubular member 10 is a box connection, and the externally threaded connection24 of the end portion 26 of the second tubular member 28 is a pin connection. In anexemplary embodiment, the internai diameter of the tubular sleeve 16 is at leastapproximately .020" greater than the outside diameters of the first and second tubularmembers, 10 and 28. In this manner, during the threaded coupling of the first and secondtubular members, 10 and 28, fluidic materials within the first and second tubular membersmay be vented from the tubular members.

[0098] In an exemplary embodiment, as illustrated in Figs. 1d and 1e, the first and secondtubular members, 10 and 28, and the tubular sleeve 16 may then be positioned withinanother structure 32 such as, for example, a wellbore, and radially expanded and plasticallydeformed, for example, by moving an expansion cône 34 through the interiors of the first andsecond tubular members. The tapered portions, 20 and 22, of the tubular sleeve 16 facilitatethe insertion and movement of the first and second tubular members within and through thestructure 32, and the movement of the expansion cône 34 through the interiors of the firstand second tubular members, 10 and 28, may be from top to bottom or from bottom to top.[0099] In an exemplary embodiment, during the radial expansion and plastic deformation ofthe first and second tubular members, 10 and 28, the tubular sleeve 16 is also radiallyexpanded and plastically deformed. In an exemplary embodiment, as a resuit, the tubularsleeve 16 may be maîntained in circumferential tension and the end portions, 14 and 26, ofthe first and second tubular members, 10 and 28, may be maîntained in circumferentialcompression.

[00100] In several exemplary embodiments, the first and second tubular members, 10and 28, are radially expanded and plastically deformed using the expansion cône 32 in a 13 012849 conventional manner and/or using one or more of the methods and apparatus disclosed in one or more of the following: (1 ) U.S. patent application serial no. 09/454,139, attorney docket no. 25791.03.02, filed on 12/3/1999, (2) U.S. patent application serial no. 09/510,913, attorney docket no. 25791.7.02, filed on 2/23/2000, (3) U.S. patent application serial no. 5 09/502,350, attorney docket no. 25791.8.02, filed on 2/10/2000, (4) U.S. patent application serial no. 09/440,338, attorney docket no. 25791.9.02, filed on 11/15/1999, (5) U.S. patentapplication serial no. 09/523,460, attorney docket no. 25791.11.02, filed on 3/10/2000, (6)U.S. patent application serial no. 09/512,895, attorney docket no. 25791.12.02, filed on2/24/2000, (7) U.S. patent application serial no. 09/511,941, attorney docket no. -, c 25791.16.02, filed on 2/24/2000, (8) U.S. patent application serial no. 09/588,946, attorney docket no. 25791.17.02, filed on 6/7/2000, (9) U.S. patent application serial no. 09/559,122,attorney docket no. 25791.23.02, filed on 4/26/2000, (10) PCT patent application serial no.PCT/US00/18635, attorney docket no. 25791.25.02, filed on 7/9/2000, (11) U.S. provisionalpatent application serial no. 60/162,671, attorney docket no. 25791.27, filed on 11/1/1999, jr.

[00101] In several alternative embodiments, the first and second tubular members, 10and 28, are radially expanded and plastically deformed using other conventional methods forradially expanding and plastically deforming tubular members such as, for example, internaipressurization and/or relier expansion devices. In an exemplary embodiment, the relierexpansion devices are the commercially available relier expansion devices available fromWeatherford International and/or as disclosed in U.S. 6,457,532 B1, the disclosure of whichis incorporated herein by reference.

[00102] The use of the tubular sleeve 16 during (a) the coupling of the first tubularmember 10 to the second tubular member 28, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 16 protects the exterior surfaces of the end portions, 14 and 26,of the first and second tubular members, 10 and 28, during handling and insertion of thetubular members within the structure 32. In this manner, damage to the exterior surfaces ofthe end portions, 14 and 26, of the first and second tubular member, 10 and 28, areprevented that could resuit in stress concentrations that could resuit in a catastrophic failureduring subséquent radial expansion operations. Furthermore, the tubular sleeve 16provides an alignment guide that facilitâtes the insertion and threaded coupling of the secondtubular member 28 to the first tubular member 10. In this manner, misaiignment that couldresuit in damage to the threaded connections, 12 and 24, of the first and second tubularmembers, 10 and 28, may be avoided. In addition, during the relative rotation of the secondtubular member with respect to the first tubular member, required during the threadedcoupling of the first and second tubular members, the tubular sleeve 16 provides anindication of to what degree the first and second tubular members are threadably coupled.For example, if the tubular sleeve 16 can be easily rotated, that would indicate that the firstand second tubular members, 10 and 28, are notfully threadably coupled and in intimatecontact with the internai flange 18 of the tubular sleeve. Furthermore, the tubular sleeve 16may prevent crack propagation during the radial expansion and plastic deformation of thefirst and second tubular members, 10 and 28. In this manner, failure modes such as, forexample, longitudinal cracks in the end portions, 14 and 26, of the first and second tubularmembers may be limited in severity or eliminated ail together. In addition, after completingthe radial expansion and plastic deformation of the first and second tubular members, 10 and28, the tubular sleeve 16 may provide a fluid tight metal-to-metal seal between interiorsurface of the tubular sleeve and the exterior surfaces of the end portions, 14 and 26, of the 15 012849 first and second tubular members. In this manner, fluidic materials are prevented frompassing through the threaded connections, 12 and 24, of the first and second tubularmembers, 10 and 28, into the annulus between the first and second tubular members andthe structure 32. Furthêrmore, because, following the radial expansion and plasticdeformation of the first and second tubular members, 10 and 28, the tubular sleeve 16 maybe maintained in circumferential tension and the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve.

[00103] Referring to Figs. 2a and 2b, in an alternative embodiment, a tubular sleeve110 having an internai flange 112 and a tapered portion 114 is coupled to the first andsecond tubular members, 10 and 28. In particular, the tubular sleeve 110 receives andmates with the end portion 14 of the first tubular member 10, and the internai flange 112 ofthe tubular sleeve is received within the annular recess 30 of the second tubular member 28proximate the end of the first tubular member. In this manner, the tubular sleeve 110 iscoupled to the end portions, 14 and 26, of the first and second tubular members, 10 and 28,and the tubular sleeve covers the end portion 14 of the first tubular member 10.

[00104] In an exemplary embodiment, the first and second tubular members, 10 and28, and the tubular sleeve 110 may then be positioned within the structure 32 and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. In an exemplary embodiment,following the radial expansion and plastic deformation of the first and second tubularmembers, 10 and 28, the tubular sleeve 110 may be maintained in circumferential tensionand the end portions, 14 and 26, of the first and second tubular members, 10 and 28, may bemaintained in circumferential compression.

[00105] The use of the tubular sleeve 110 during (a) the coupling of the first tubularmember 10 to the second tubular member 28, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 110 protects the exterior surface of the end portion 14 of the firsttubular member 10 during handling and insertion of the tubular members within the structure32. In this manner, damage to the exterior surfaces of the end portion 14 of the first tubularmember 10 is prevented that could resuit in stress concentrations that could resuit in acatastrophic failure during subséquent radial expansion operations. In addition, during therelative rotation of the second tubular member with respect to the first tubular member,required during the threaded coupling of the first and second tubular members, the tubularsleeve 110 provides an indication of to what degree the first and second tubular membersare threadably coupled. For example, if the tubular sleeve 110 can be easily rotated, that 16 012849 would indicate that the first and second tubular members, 10 and 28, are not fully threadably coupled and in intimate contact with the internai flange 112 of the tubular sleeve.

Furthermore, the tubular sleeve 110 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 10 and 28. In 5 this manner, failure modes such as, for example, longitudinal cracks in the end portions, 14and 26, of the first and second tubular members may be limited in severity or eliminated ailtogether. In addition, after completing the radial expansion and plastic deformation of thefirst and second tubular members, 10 and 28, the tubular sleeve 110 may provide a fluid tightmetal-to-metal seal between interior surface of the tubular sleeve and the exterior surface of ,0 the end portionl 4 of the first tubular member. In this manner, fluidic materials are preventedfrom passing through the threaded connections, 12 and 24, of the first and second tubularmembers, 10 and 28, into the annulus between the first and second tubular members andthe structure 32. Furthermore, because, following the radial expansion and plasticdeformation of the first and second tubular members, 10 and 28, the tubular sleeve 110 maybe maintained in circumferential tension and the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve.

[00106] Referring to Figs. 3a and 3b, in an alternative embodiment, a tubular sleeve210 having an internai flange 212, tapered portions, 214 and 216, at opposite ends, and 2G annular sealing members, 218 and 220, positioned on opposite sides of the internai flange,is coupled to the first and second tubular members, 10 and 28. In particular, the tubularsleeve 210 receives and mates with the end portions, 14 and 26, of the first and secondtubular members, 10 and 28, and the internai flange 212 of the tubular sleeve is receivedwithin the annular recess 30 of the second tubular member 28 proximate the end of the first 25 tubular member. Furthermore, the sealing members, 218 and 220, of the tubular sleeve 210engage and fluidicly seal the interface between the tubular sleeve and the end portions, 14and 26, of the first and second tubular members, 10 and 28. In this manner, the tubularsleeve 210 is coupled to the end portions, 14 and 26, of the first and second tubularmembers, 10 and 28, and the tubular sleeve covers the end portions, 14 and 26, of the firstand second tubular members, 10 and 28.

[00107] In an exemplary embodiment, the first and second tubular members, 10 and28, and the tubular sleeve 210 may then be positioned within the structure 32 and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. In an exemplary embodiment, 35 following the radial expansion and plastic deformation of the first and second tubular members, 10 and 28, the tubular sleeve 210 may be maintained in circumferential tensionand the end portions, 14 and 26, of the first and second tubular members, 10 and 28, may be 17 012849 maintained in circumferential compression.

[00108] The use of the tubular sleeve 210 during (a) the coupling of the first tubular member 10 to the second tubular member 28, (b) the placement of the first and second tubular members in the structure 32, and (c) the radial expansion and plastic deformation of 5 the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 210 protects the exterior surfaces of the end portions, 14 and 26,of the first and second tubular members, 10 and 28, during handling and insertion of thetubular members within the structure 32. In this manner, damage to the exterior surfaces ofthe end portions, 14 and 26, of the first and second tubular members, 10 and 28, is 10 prevented that could resuit in stress concentrations that could resuit in a catastrophic failureduring subséquent radial expansion operations. In addition, during the relative rotation of thesecond tubular member with respect to the first tubular member, required during the threadedcoupling of the first and second tubular members, the tubular sleeve 210 provides anindication of to what degree the first and second tubular members are threadably coupled. X5 For example, if the tubular sleeve 210 can be easily rotated, that would indicate that the firstand second tubular members, 10 and 28, are not fully threadably coupled and in intimatecontact with the internai flange 212 of the tubular sleeve. Furthermore, the tubular sleeve210 may prevent crack propagation during the radial expansion and plastic deformation ofthe first and second tubular members, 10 and 28. In this manner, failure modes such as, for 20 example, longitudinal cracks in the end portions, 14 and 26, of the first and second tubularmembers, 10 and 28, may be limited in severity or eliminated ail together. In addition, aftercompleting the radial expansion and plastic deformation of the first and second tubularmembers, 10 and 28, the tubular sleeve 210 may provide a fluid tight metal-to-metal sealbetween intérieur surface of the tubular sleeve and the exterior surfaces of the end portions,14 25 and 26, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 12 and 24, of the first and secondtubular members, 10 and 28, into the annulus between the first and second tubular membersand the structure 32. Furthermore, because, following the radial expansion and plasticdeformation of the first and second tubular members, 10 and 28, the tubular sleeve 210 may 30 be maintained in circumferential tension and the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve.

[00109] Referring to Figs. 4a and 4b, in an alternative embodiment, a tubular sleeve 310 having an internai flange 312, tapered portions, 314 and 316, at opposite ends, and an 35 annular sealing member 318 positioned on the exterior surface of the tubular sleeve, is coupled to the first and second tubular members, 10 and 28. In particular, the tubular sleeve 310 receives and mates with the end portions, 14 and 26, of the first and second tubular 18 012849 members, 10 and 28, and the internai flange 312 of the tubular sleeve is received within the annular recess 30 of the second tubular member 28 proximate the end of the first tubular member. In this manner, the tubular sleeve 310 is coupled to the end portions, 14 and 26, of the first and second tubular members, 10 and 28, and the tubular sleeve covers the end portions, 14 and 26, of the first and second tubular members, 10 and 28.

[00110] In an exemplary embodiment, the first and second tubular members, 10 and28, and the tubular sleeve 310 may then be positioned within the structure 32 and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. In an exemplary embodiment, 10 following the radial expansion and plastic deformation of the first and second tubular members, 10 and 28, the tubular sleeve 310 may be maintained in circumferential tensionand the end portions, 14 and 26, of the first and second tubular members, 10 and 28, may bemaintained in circumferential compression. Furthemnore, in an exemplary embodiment,following the radial expansion and plastic deformation of the first and second tubular 15 members, 10 and 28, the annular sealing member 318 circumferentially engages the interiorsurface of the structure 32 thereby preventing the passage of fluidic materials through theannulus between the tubular sleeve 310 and the structure. In this manner, the tubular sleeve310 may provide an expandable packer element.

[00111] The use of the tubular sleeve 310 during (a) the coupling of the first tubular 2q member 10 to the second tubular member 28, (b) the placement of the first and second tubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 310 proteçts the exterior surfaces of the end portions, 14 and 26,of the first and second tubular members, 10 and 28, during handling and insertion of the ,, tubular members within the structure 32. In this manner, damage to the exterior surfaces ofthe end portions, 14 and 26, of the first and second tubular members, 10 and 28, isprevented that could resuit in stress concentrations that could resuit in a catastrophic failureduring subséquent radial expansion operations. In addition, during the relative rotation of thesecond tubular member with respect to the first tubular member, required during the threaded 30 coupling of the first and second tubular members, the tubular sleeve 310 provides an indication of to what degree the first and second tubular members are threadably coupled.

For example, if the tubular sleeve 310 can be easily rotated, that would indicate that the firstand second tubular members, 10 and 28, are not fully threadably coupled and in intimatecontact with the internai flange 312 of the tubular sleeve. Furthermore, the tubular sleeve 35 310 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 10 and 28. In this manner, failure modes such as, forexample, longitudinal cracks in the end portions, 14 and 26, of the first and second tubular 19 012849 members, 10 and 28, may be limited in severity or eliminated ail together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 10 and 28, the tubular sleeve 310 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve and the exterior surfaces of the end portions,14 5 and 26, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 12 and 24, of the first and secondtubular members, 10 and 28, into the annulus between the first and second tubular membersand the structure 32. Furthermore, because, foilowing the radial expansion and plasticdeformation of the first and second tubular members, 10 and 28, the tubular sleeve 310 may ΙΟ be maintained in circumferential tension and the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve. In addition,because, foilowing the radial expansion and plastic deformation of the first and secondtubular members, 10 and 28, the annular sealing member 318 may circumferentially engage î * the interior surface of the structure 32, the tubular sleeve 310 may provide an expandablepacker element.

[00112] Referring to Figs. 5a and 5b, in an alternative embodiment, a non-metallictubular sleeve 410 having an internai flange 412, and tapered portions, 414 and 416, atopposite ends, is coupled to the first and second tubular members, 10 and 28. In particular,the tubular sleeve 410 receives and mates with the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, and the internai flange 412 of the tubular sleeve isreceived within the annular recess 30 of the second tubular member 28 proximate the end ofthe first tubular member. In this manner, the tubular sleeve 410 is coupled to the endportions, 14 and 26, of the first and second tubular members, 10 and 28, and the tubular <•3 sleeve covers the end portions, 14 and 26, of the first and second tubular members, 10 and28.

[00113] In several exemplary embodiments, the tubular sleeve 410 may be plastic,ceramic, elastomeric, composite and/or a frangible material.

[00114] In an exemplary embodiment, the first and second tubular members, 10 and 30 28, and the tubular sleeve 410 may then be positioned within the structure 32 and radially expanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. In an exemplary embodiment,foilowing the radial expansion and plastic deformation of the first and second tubular members, 10 and 28, the tubular sleeve 410 may be maintained in circumferential tension 35 and the end portions, 14 and 26, of the first and second tubular members, 10 and 28, may bemaintained in circumferential compression. Furthermore, in an exemplary embodiment,during the radial expansion and plastic deformation of the first and second tubular members, 20 Π 1?849 10 and 28, the tubular sleeve 310 may be broken off of the First and second tubular members.

[00115] The use of the tubular sleeve 410 during (a) the coupling of the first tubular member 10 to the second tubular member 28, (b) the placement of the first and second 5 tubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 410 protects the exterior surfaces of the end portions, 14 and 26,of the first and second tubular members, 10 and 28, during handling and insertion of thetubular members within the structure 32. In this manner, damage to the exterior surfaces ofthe end portions, 14 and 26, of the first and second tubular members, 10 and 28, isprevented that could resuit in stress concentrations that could resuit in a catastrophic failureduring subséquent radial expansion operations. In addition, during the relative rotation of thesecond tubular member with respect to the first tubular member, required during the threadedcoupling of the first and second tubular members, the tubular sleeve 410 provides an 15 indication of to what degree the first and second tubular members are threadably coupled.

For example, if the tubular sleeve 410 can be easily rotated, that would indicate that the firstand second tubular members, 10 and 28, are not fully threadably coupled and in intimatecontact with the internai flange 412 of the tubular sleeve. Furthermore, the tubular sleeve410 may prevent crack propagation during the radial expansion and plastic deformation of ;.o the first and second tubular members, 10 and 28. In this manner, failure modes such as, forexample, longitudinal cracks in the end portions, 14 and 26, of the first and second tubularmembers, 10 and 28, may be limited in severity or eliminated ail together. In addition, aftercompleting the radial expansion and plastic deformation of the first and second tubularmembers, 10 and 28, the tubular sleeve 410 may provide a fluid tight metal-to-metal seal 25 between interior surface of the tubular sleeve and the exterior surfaces of the end portions,14and 26, of the first and second tubular members. In this manner, fluidic materials areprevented from passing through the threaded connections, 12 and 24, of the first and secondtubular members, 10 and 28, into the annulus between the first and second tubular membersand the structure 32. Furthermore, because, following the radial expansion and plastic jq deformation of the first and second tubular members, 10 and 28, the tubular sleeve 410 maybe maintained in circumferential tension and the end portions, 14 and 26, of the first andsecond tubular members, 10 and 28, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve. In addition,because, during the radial expansion and plastic deformation of the first and second tubular 35 members, 10 and 28, the tubular sleeve 410 may be broken off of the first and secondtubular members, the final outside diameter of the first and second tubular members maymore closely match the inside diameter of the structure 32. 21 012849 [00116] Referring to Fig. 6a, in an exemplary embodiment, a tubular sleeve 510 includes an internai flange 512, tapered portions, 514 and 516, at opposite ends, and defines one or more axial slots 518. In an exemplary embodiment, during the radial expansion and plastic deformation of the first and second tubular members, 10 and 28, the axial slots 518 5 reduce the required radial expansion forces.

[00117] Referring to Fig. 6b, in an exemplary embodiment, a tubular sleeve 610includes an internai flange 612, tapered portions, 614 and 616, at opposite ends, and definesone or more offset axial slots 618. In an exemplary embodiment, during the radial expansionand plastic deformation of the first and second tubular members, 10 and 28, the axial slots • q 618 reduce the required radial expansion forces.

[00118] Referring to Fig. 6c, in an exemplary embodiment, a tubular sleeve 710includes an internai flange 712, tapered portions, 714 and 716, at opposite ends, and definesone or more radial openings 718. In an exemplary embodiment, during the radial expansionand plastic deformation of the first and second tubular members, 10 and 28, the radialopenings 718 reduce the required radial expansion forces.

[00119] Referring to Fig. 6d, in an exemplary embodiment, a tubular sleeve 810includes an internai flange 812, tapered portions, 814 and 816, at opposite ends, and definesone or more axial slots 818 that extend from the ends of the tubular sleeve. In an exemplaryembodiment, during the radial expansion and plastic deformation of the first and second i ü tubular members, 10 and 28, the axial slots 818 reduce the required radial expansion forces.[00120] Referring to Fig. 7a, a first tubular member 910 includes an internally threadedconnection 912 at an end portion 914 and a recessed portion 916 having a reduced outsidediameter. As illustrated in Fig. 7b, a first end of a tubular sleeve 918 that includes annularsealing members, 920 and 922, at opposite ends, tapered portions, 924 and 926, at one end, 25 and tapered portions, 928 and 930, at another end is then mounted upon and receives theend portion 914 of the first tubular member 910. In an exemplary embodiment, a résilientretaining ring 930 is positioned between the lowerend of the tubular sleeve 918 and therecessed portion 916 of the first tubular member 910 in orderto couple the tubular sleeve tothe first tubular member. In an exemplary embodiment, the résilient retaining ring 930 is asplit ring having a toothed surface in orderto lock the tubular sleeve 918 in place.

[00121] As illustrated in Fig. 7c, an externally threaded connection 934 of an endportion 936 of a second tubular member 938 having a recessed portion 940 having areduced outside diameter is then positioned within the tubular sleeve 918 and threadablycoupled to the internally threaded connection 912 of the end portion 914 of the first tubularmember 910. In an exemplary embodiment, a résilient retaining ring 942 is positionedbetween the upper end of the tubular sleeve 918 and the recessed portion 940 of the secondtubular member 938 in order to couple the tubular sleeve to the second tubular member. In 22 012849 an exemplary embodiment, the résilient retaining ring 942 is a split ring having a toothed surface in order to lock the tubular sleeve 918 in place.

[00122] In an exemplary embodiment, the internally threaded connection 912 of the end portion 914 of the first tubular member 910 is a box connection, and the externally 5 threaded connection 934 of the end portion 936 of the second tubular member 938 is a pinconnection. In an exemplary embodiment, the internai diameter of the tubular sleeve 918 isat least approximately .020" greater than the outside diameters of the end portions, 914 and936, of the first and second tubular members, 910 and 938. In this manner, during thethreaded coupling of the first and second tubular members, 910 and 938, fluidic materials iü within the first and second tubular members may be vented from the tubular members.

[0019] In an exemplary embodiment, as illustrated in Figs. 7d and 7e, the first and secondtubular members, 910 and 938, and the tubular sleeve 918 may then be positioned withinanother structure 32 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by moving an expansion cône 34 through the interiors of the first and 15 second tubular members. The tapered portions, 924 and 928, of the tubular sleeve 918facilitate the insertion and movement of the first and second tubular members within andthrough the structure 32, and the movement of the expansion cône 34 through the interiors ofthe first and second tubular members, 910 and 938, may be from top to bottom or frombottom to top. 20 [00123] In an exemplary embodiment, during the radial expansion and plastic deformation of the first and second tubular members, 910 and 938, the tubular sleeve 918 isalso radially expanded and plastically deformed. In an exemplary embodiment, as a resuit,the tubular sleeve 918 may be maintained in circumferential tension and the end portions, 914 and 936, of the first and second tubular members, 910 and 938, may be maintained incircumferential compression.

[00124] The use of the tubular sleeve 918 during (a) the coupling of the first tubularmember 910 to the second tubular member 938, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. For 30 example, the tubular sleeve 918 protects the exterior surfaces of the end portions, 914 and936, of the first and second tubular members, 910 and 938, during handling and insertion ofthe tubular members within the structure 32. In this manner, damage to the exterior surfacesof the end portions, 914 and 936, of the first and second tubular member, 910 and 938, are prevented that could resuit in stress concentrations that could resuit in a catastrophic failure 35 during subséquent radial expansion operations. Furthermore, the tubular sleeve 918provides an alignment guide that facilitâtes the insertion and threaded coupling of the secondtubular member 938 to the first tubular member 910. In this manner, misalignment that could 23 012849 resuit in damage to the threaded connections, 912 and 934, of the first and second tubularmembers, 910 and 938, may be avoided. Furthermore, the tubular sleeve 918 may preventcrack propagation during the radial expansion and plastic deformation of the first and secondtubular members, 910 and 938. In this manner, failure modes such as, for example,longitudinal cracks in the end portions, 914 and 936, of the first and second tubular membersmay be limited in severity or eliminated ail together. In addition, after completing the radialexpansion and plastic deformation of the first and second tubular members, 910 and 938, thetubular sleeve 918 may provide a fluid tight metal-to-metal seal between interior surface ofthe tubular sleeve and the exterior surfaces of the end portions, 914 and 936, of the first andsecond tubular members. In this manner, fluidic materials are prevented from passingthrough the threaded connections, 912 and 934, of the first and second tubular members, 910 and 938, into the annulus between the first and second tubular members and thestructure 32. Furthermore, because, following the radial expansion and plastic deformationof the first and second tubular members, 910 and 938, the tubular sleeve 918 may bemaintained in circumferential tension and the end portions, 914 and 936, of the first andsecond tubular members, 910 and 938, may be maintained in circumferential compression,axial loads and/or torque loads may be transmitted through the tubular sleeve. In addition,the annular sealing members, 920 and 922, of the tubular sleeve 918 may provide a fluidtight seal between the tubular sleeve and the end portions, 914 and 936, of the first andsecond tubular members, 910 and 938.

[00125] Referring to Fig. 8a, a first tubular member 1010 includes an internallythreaded connection 1012 atan end portion 1014 and a recessed portion 1016 having areduced outside diameter. As illustrated in Fig. 8b, a first end of a tubular sleeve 1018 thatincludes annular sealing members, 1020 and 1022, at opposite ends, tapered portions, 1024and 1026, atone end, and tapered portions, 1028 and 1030, atanotherend is then mountedupon and receives the end portion 1014 of the first tubular member 1010. In an exemplaryembodiment, as illustrated in Fig. 8c, the end of the tubular sleeve 1018 is then crimped ontothe recessed portion 1016 of the first tubular member 1010 in orderto couple the tubularsleeve to the first tubular member.

[00126] As illustrated in Fig. 8d, an externally threaded connection 1032 of an endportion 1034 of a second tubular member 1036 having a recessed portion 1038 having areduced external diameter is then positioned within the tubular sleeve 1018 and threadablycoupled to the internally threaded connection 1012 of the end portion 1014 of the first tubularmember 1010. In an exemplary embodiment, as illustrated in Fig. 8e, the other end of thetubular sleeve 1018 is then crimped into the recessed portion 1038 of the second tubularmember 1036 in order to couple the tubular sleeve to the second tubular member.

[00127] In an exemplary embodiment, the internally threaded connection 1012 of the 24 012849 end portion 1014 of the first tubular member 1010 is a box connection, and the externally threaded connection 1032 of the end portion 1034 of the second tubular member 1036 is a pin connection. In an exemplary embodiment, the internai diameter of the tubular sleeve 1018 is at least approximately .020" greater than the outside diameters of the end portions, 5 1014 and 1034, of the first and second tubular members, 1010 and 1036. In this manner, during the threaded coupling of the first and second tubular members, 1010 and 1036, fluidicmaterials within the first and second tubular members may be vented from the tubularmembers.

[00128] In an exemplary embodiment, as illustrated in Figs. 8f and 8g, the first and 10 second tubular members, 1010 and 1036, and the tubular sleeve 1018 may then bepositioned within another structure 32 such as, for example, a wellbore, and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1010 and 1036, may be 15 from top to bottom or from bottom to top.

[00129] In an exemplary embodiment, during the radial expansion and plasticdeformation of the first and second tubular members, 1010 and 1036, the tubular sleeve1018 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1018 may be maintained in circumferential tension and the end 20 portions, 1014 and 1034, of the first and second tubular members, 1010 and 1036, may bemaintained in circumferential compression.

[00130] The use of the tubular sleeve 1018 during (a) the coupling of the first tubularmember 1010 to the second tubular member 1036, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation of 45 the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 1018 protects the exterior surfaces of the end portions, 1014 and1034, of the first and second tubular members, 1010 and 1036, during handling and insertionof the tubular members within the structure 32. In this manner, damage to the exteriorsurfaces of the end portions, 1014 and 1034, of the first and second tubular members, 1010 30 and 1036, are prevented that could resuit in stress concentrations that could resuit in a catastrophic failure during subséquent radial expansion operations. Furthermore, the tubularsleeve 1018 provides an alignment guide that facilitâtes the insertion and threaded couplingof the second tubular member 1036 to the first tubular member 1010. In this manner,misalignment that could resuit in damage to the threaded connections, 1012 and 1032, of the 35 first and second tubular members, 1010 and 1036, may be avoided. Furthermore, the tubular sleeve 1018 may prevent crack propagation during the radial expansion and plasticdeformation of the first and second tubular members, 1010 and 1036. In this manner, failure 25 012849 modes such as, for example, longitudinal cracks in the end portions, 1014 and 1034, of the first and second tubular members may be limited in severity or eliminated ail together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 1010 and 1036, the tubular sleeve 1018 may provide a fluid tight metal-to- 5 métal seal between interior surface of the tubular sleeve and the exterior surfaces of the end portions, 1014 and 1034, of the first and second tubular members. In this manner, fluidicmaterials are prevented from passing through the threaded connections, 1012 and 1032, ofthe first and second tubular members, 1010 and 1036, into the annulus between the first andsecond tubular members and the structure 32. Furthermore, because, following the radial iy expansion and plastic deformation of the first and second tubular members, 1010 and 1036,the tubular sleeve 1018 may be maintained in circumferential tension and the end portions,1014 and 1034, of the first and second tubular members, 1010 and 1036, may be maintainedin circumferential compression, axial loads and/or torque loads may be transmitted throughthe tubular sleeve. In addition, the annularsealing members, 1020 and 1022, of the tubular i s, sleeve 1018 may provide a fluid tight seal between the tubular sleeve and the end portions, 1014 and 1034, of the first and second tubular members, 1010 and 1036.

[00131] Referring to Fig. 9a, a first tubular member 1110 includes an internallythreaded connection 1112 at an end portion 1114. As illustrated in Fig. 9b, a first end of atubular sleeve 1116 having tapered portions, 1118 and 1120, at opposite ends, is then 20 mounted upon and receives the end portion 1114 of the first tubular member 1110. In an exemplary embodiment, a toothed résilient retaining ring 1122 is then attached to first tubularmember 1010 below the end of the tubular sleeve 1116 in order to couple the tubular sleeveto the first tubular member.

[00132] As illustrated in Fig. 9c, an externally threaded connection 1124 of an end 25 portion 1126 of a second tubular member 1128 is then positioned within the tubular sleeve 1116 and threadably coupled tothe internally threaded connection 1112 of the end portion1114 of the first tubular member 1110. In an exemplary embodiment, a toothed résilientretaining ring 1130 is then attached to second tubular member 1128 above the end of thetubular sleeve 1116 in order to couple the tubular sleeve to the second tubular member. 30 [00133] In an exemplary embodiment, the internally threaded connection 1112 of the end portion 1114 of the first tubular member 1110 is a box connection, and the externallythreaded connection 1124 of the end portion 1126 of the second tubular member 1128 is apin connection. In an exemplary embodiment, the internai diameter of the tubular sleeve1116 is at least approximately .020" greater than the outside diameters of the end portions,1114 and 1126, of the first and second tubular members, 1110 and 1128. In this manner,during the threaded coupling of the first and second tubular members, 1110 and 1128, fluidicmaterials within the first and second tubular members may be vented from the tubular 26

members.

[00134] In an exemplary embodiment, as illustrated in Figs. 9d and 9e, the first and second tubular members, 1110 and 1128, and the tubular sleeve 1116 may then be positioned within another structure 32 such as, for example, a wellbore, and radially 5 expanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1110 and 1128, may befrom top to bottom or from bottom to top.

[00135] In an exemplary embodiment, during the radial expansion and plastic 10 deformation of the first and second tubular members, 1110 and 1128, the tubular sleeve 1116 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1116 may be maintained in circumferential tension and the endportions, 1114 and 1126, of the first and second tubular members, 1110 and 1128, may bemaintained in circumferential compression. 15 [00136] The use of the tubular sleeve 1116 during (a) the coupling of the first tubular member 1110 to the second tubular member 1128, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 1116 protects the exterior surfaces of the end portions, 1114 and zu 1126, of the first and second tubular members, 1110 and 1128, during handling and insertionof the tubular members within the structure 32. In this manner, damage to the exteriorsurfaces of the end portions, 1114 and 1126, of the first and second tubular members, 1110and 1128, are prevented that could resuit in stress concentrations that could resuit in acatastrophic failure during subséquent radial expansion operations. Furthermore, the tubular 25 sleeve 1116 provides an alignment guide that facilitâtes the insertion and threaded couplingof the second tubular member 1128 to the first tubular member 1110. In this manner,misalignment that could resuit in damage to the threaded connections, 1112 and 1124, of thefirst and second tubular members, 1110 and 1128, may be avoided. Furthermore, thetubular sleeve 1116 may prevent crack propagation during the radial expansion and plastic 30 deformation of the first and second tubular members, 1110 and 1128. In this manner, failuremodes such as, for example, longitudinal cracks in the end portions, 1114 and 1126, of thefirst and second tubular members may be limited in severity or eliminated ali together. Inaddition, after completing the radial expansion and plastic deformation of the first and secondtubular members, 1110 and 1128, the tubular sleeve 1116 may provide a fluid tight metal-to- 35 métal seal between interior surface of the tubular sleeve and the exterior surfaces of the endportions, 1114 and 1128, of the first and second tubular members. In this manner, fluidicmaterials are prevented from passing through the threaded connections, 1112 and 1124, of 27 012849 the first and second tubular members, 1110 and 1128, into the annulus between the first and second tubular members and the structure 32. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 1110 and 1128, the tubular sleeve 1116 may be maintained in circumferential tension and the end portions, 5 1114 and 1126, of the first and second tubular members, 1110 and 1128, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted throughthe tubular sleeve.

[00137] Referring to Fig. 10a, a first tubular member 1210 includes an internallythreaded connection 1212 at an end portion 1214. As illustrated in Fig. 10b, a first end of a 10 tubular sleeve 1216 having tapered portions, 1218 and 1220, at one end and tapered portions, 1222 and 1224, at another end, is then mounted upon and receives the end portion1114 of the first tubular member 1110. In an exemplary embodiment, a résilient elastomericO-ring 1226 is then positioned on the first tubular member 1210 below the tapered portion1224 of the tubular sleeve 1216 in orderto couple the tubular sleeve to the first tubular 15 member.

[00138] As illustrated in Fig. 10c, an externally threaded connection 1228 of an end portion 1230 of a second tubular member 1232 is then positioned within the tubular sleeve1216 and threadably coupled to the internally threaded connection 1212 of the end portion1214 of the first tubular member 1210. In an exemplary embodiment, a résilient elastomericO-ring 1234 is then positioned on the second tubular member 1232 below the taperedportion 1220 of the tubular sleeve 1216 in order to couple the tubular sleeve to the firsttubular member.

[00139] In an exemplary embodiment, the internally threaded connection 1212 of theend portion 1214 of the first tubular member 1210 is a box connection, and the externally 25 threaded connection 1228 of the end portion 1230 of the second tubular member 1232 is a pin connection. In an exemplary embodiment, the internai diameter of the tubular sleeve1216 is at least approximately .020" greaterthan the outside diameters of the end portions,1214 and 1230, of the first and second tubular members, 1210 and 1232. In this manner,during the threaded coupling of the first and second tubular members, 1210 and 1232, fluidic 30 materials within the first and second tubular members may be vented from the tubularmembers.

[00140] In an exemplary embodiment, as illustrated in Figs. 10d and 10e, the first andsecond tubular members, 1210 and 1232, and the tubular sleeve 1216 may then bepositioned within another structure 32 such as, for example, a wellbore, and radially 35 expanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1210 and 1232, may be 28 012849 from top to bottom or from bottom to top.

[00141] In an exemplary embodiment, during the radial expansion and plastic deformation of the first and second tubular members, 1210 and 1232, the tubular sleeve 1216 is also radially expanded and plastically deformed. In an exemplary embodiment, as a 5 resuit, the tubular sleeve 1216 may be maintained in circumferential tension and the endportions, 1214 and 1230, of the first and second tubular members, 1210 and 1232, maybemaintained in circumferential compression.

[00142] The use of the tubular sleeve 1216 during (a) the coupling of the first tubularmember 1210 to the second tubular member 1232, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 1216 protects the exterior surfaces of the end portions, 1214 and1230, of the first and second tubular members, 1210 and 1232, during handling and insertionof the tubular members within the structure 32. In this manner, damage to the exterior 15 surfaces of the end portions, 1214 and 1230, of the first and second tubular members, 1210 and 1232, are prevented that could resuit in stress concentrations that could resuit in acatastrophic failure during subséquent radial expansion operations. Furthermore, the tubularsleeve 1216 provides an alignment guide that facilitâtes the insertion and threaded couplingof the second tubular member 1232 to the first tubular member 1210. In this manner, 2ff misalignment that could resuit in damage to the threaded connections, 1212 and 1228, of thefirst and second tubular members, 1210 and 1232, may be avoided. Furthermore, thetubular sleeve 1216 may prevent crack propagation during the radial expansion and plasticdeformation of the first and second tubular members, 1210 and 1232. In this manner, failuremodes such as, for example, longitudinal cracks in the end portions, 1214 and 1230, of the 25 first and second tubular members may be limited in severity or eliminated ail together. In addition, after completing the radial expansion and plastic deformation of the first and secondtubular members, 1210 and 1232, the tubular sleeve 1216 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve and the exterior surfaces of the endportions, 1214 and 1230, of the first and second tubular members. In this manner, fluidicmaterials are prevented from passing through the threaded connections, 1212 and 1228, ofthe first and second tubular members, 1210 and 1232, into the annulus between the first andsecond tubular members and the structure 32. Furthermore, because, following the radialexpansion and plastic deformation of the first and second tubular members, 1210 and 1232,the tubular sleeve 1216 may be maintained in circumferential tension and the end portions, 35 1214 and 1230, of the first and second tubular members, 1210 and 1232, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve. 29 012849 [00143] Referringto Fig. 11a, a firsttubular member 1310 includesan internally threaded connection 1312 at an end portion 1314. As illustrated in Fig. 11b, a first end of a tubular sleeve 1316 having tapered portions, 1318 and 1320, at opposite ends is then mounted upon and receives the end portion 1314 of the first tubular member 1310. In an 5 exemplary embodiment, an annular résilient retaining member 1322 is then positioned on thefirst tubular member 1310 below the bottom end of the tubular sleeve 1316 in ordêr to couplethe tubular sleeve to the first tubular member.

[00144] As illustrated in Fig. 11c, an externally threaded connection 1324 of an endportion 1326 of a second tubular member 1328 is then positioned within the tubular sleeveiü 1316 and threadably coupled to the internally threaded connection 1312 of the end portion 1314 of the firsttubular member 1310. In an exemplary embodiment, an annular résilientretaining member 1330 is then positioned on the second tubular member 1328 above the topend of the tubular sleeve 1316 in orderto couple the tubular sleeve to the second tubularmember. î5 [00145] In an exemplary embodiment, the internally threaded connection 1312 of theend portion 1314 of the first tubular member 1310 is a box connection, and the externallythreaded connection 1324 of the end portion 1326 of the second tubular member 1328 is apin connection. In an exemplary embodiment, the internai diameter of the tubular sleeve1316 is at least approximately .020" greater than the outside diameters of the end portions, Z3 1314 and 1326, of the first and second tubular members, 1310 and 1328. In this manner, during the threaded coupling of the first and second tubular members, 1310 and 1328, fluidicmaterials within the first and second tubular members may be vented from the tubularmembers.

[00146] In an exemplary embodiment, as illustrated in Figs. 11 d and 11 e, the first and 25 second tubular members, 1310 and 1328, and the tubular sleeve 1316 may then bepositioned within another structure 32 such as, for example, a wellbore, and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1310 and 1328, may be 30 from top to bottom or from bottom to top.

[00147] In an exemplary embodiment, during the radial expansion and plasticdeformation of the first and second tubular members, 1310 and 1328, the tubular sleeve1316 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1316 may be maintained in circumferential tension and the end 35 portions, 1314 and 1326, of the first and second tubular members, 1310 and 1328, may bemaintained in circumferential compression.

[00148] The use of the tubular sleeve 1316 during (a) the coupling of the firsttubular 30

member 1310 to the second tubular member 1328, (b) the placement of the first and secondtubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 1316 protects the exterior surfaces of the end portions, 1314 and1326, of the first and second tubular members, 1310 and 1328, during handling and insertionof the tubular members within the structure 32. In this manner, damage to the exteriorsurfaces of the end portions, 1314 and 1326, of the first and second tubular members, 1310and 1328, are prevented that could resuit in stress concentrations that could resuit in acatastrophic failure during subséquent radial expansion operations. Furthermore, the tubularsleeve 1316 provides an alignment guide that facilitâtes the insertion and threaded couplingof the second tubular member 1328 to the first tubular member 1310. In this manner,misalignment that could resuit in damage to the threaded connections, 1312 and 1324, of thefirst and second tubular members, 1310 and 1328, may be avoided. Furthermore, thetubular sleeve 1316 may prevent crack propagation during the radial expansion and plasticdeformation of the first and second tubular members, 1310 and 1328. In this manner, failuremodes such as, for example, longitudinal cracks in the end portions, 1314 and 1326, of thefirst and second tubular members may be limited in severity or eliminated ali together. Inaddition, after completing the radial expansion and plastic deformation of the first and secondtubular members, 1310 and 1328, the tubular sleeve 1316 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve and the exterior surfaces of the endportions, 1314 and 1326, of the first and second tubular members. In this manner, fluidicmaterials are prevented from passing through the threaded connections, 1312 and 1324, ofthe first and second tubular members, 1310 and 1328, into the annulus between the first andsecond tubular members and the structure 32. Furthermore, because, following the radialexpansion and plastic deformation of the First and second tubular members, 1310 and 1328,the tubular sleeve 1316 may be maintained in circumferential tension and the end portions,1314 and 1326, of the first and second tubular members, 1310 and 1328, may be maintainedin circumferential compression, axial loads and/or torque loads may be transmitted throughthe tubular sleeve.

[00149] Referring to Fig. 12a, a first tubular member 1410 includes an internallythreaded connection 1412 and an annular recess 1414 atan end portion 1416. As illustratedin Fig. 12b, a first end of a tubular sleeve 1418 that includes an external flange 1420 andtapered portions, 1422 and 1424, at opposite ends is then mounted within the end portion1416 of the first tubular member 1410. In an exemplary embodiment, the external flange1420 of the tubular sleeve 1418 is received within and is supported by the annular recess1414 of the end portion 1416 of the first tubular member 1410. As illustrated in Fig. 12c, anexternally threaded connection 1426 of an end portion 1428 of a second tubular member 31 012849 1430 is then positioned around a second end of the tubular sleeve 1418 and threadablycoupled to the internally threaded connection 1412 of the end portion 1414 of the first tubularmember 1410. In an exemplary embodiment, the external flange 1420 of the tubular sleeve 1418 mates with and is received within the annular recess 1416 of the end portion 1414 of 5 the first tubular member 1410, and the extemal flange of the tubular sleeve is retained in theannular recess by the end portion 1428 of the second tubular member 1430. Thus, thetubular sleeve 1416 is coupled to and is surrounded by the internai surfaces of the first andsecond tubular members, 1410 and 1430.

[00150] In an exemplary embodiment, the internally threaded connection 1412 of the

O end portion 1414 of the first tubular member 1410 is a box connection, and the externallythreaded connection 1426 of the end portion 1428 of the second tubular member 1430 is apin connection. In an exemplary embodiment, the extemal diameter of the tubular sleeve1418 is at least approximately .020" less than the inside diameters of the first and secondtubular members, 1410 and 1430. In this manner, during the threaded coupling of the firstand second tubular members, 1410 and 1430, fluidic materials within the first and secondtubular members may be vented from the tubular members.

[00151] In an exemplary embodiment, as illustrated in Figs. 12d and 12e, the first andsecond tubular members, 1410 and 1430, and the tubular sleeve 1418 may then bepositioned within another structure 32 such as, for example, a wellbore, and radially 2.0 expanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The tapered portions, 1422 and 1424,of the tubular sleeve 1418 facilitate the movement of the expansion cône 34 through the firstand second tubular members, 1410 and 1430, and the movement of the expansion cône 34through the interiors of the first and second tubular members, 1410 and 1430, may be from 25 top to bottom or from bottom to top.

[00152] In an exemplary embodiment, during the radial expansion and plasticdeformation of the first and second tubular members, 1410 and 1430, the tubular sleeve1418 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1418 may be maintained in circumferential compression and the 30 end portions, 1414 and 1428, of the first and second tubular members, 1410 and 1430, maybe maintained in circumferential compression.

[00153] In several alternative embodiments, the first and second tubular members,1410 and 1430, are radially expanded and plastically deformed using other conventionalmethods for radially expanding and plastically deforming tubular members such as, forexample, internai pressurization and/or roller expansion devices.

[00154] The use of the tubular sleeve 1418 during (a) the coupling of the first tubularmember 1410 to the second tubular member 1430, (b) the placement of the first and second 32

tubular members in the structure 32, and (c) the radial expansion and plastic deformation ofthe first and second tubular members provides a number of significant benefits. Forexample, the tubular sleeve 1418 provides an alignment guide that facilitâtes the insertionand threaded coupling of the second tubular member 1430 to the first tubular member 1410.In this manner, misalignmentthatcould resuit in damage to the threaded connections, 1412and 1426, of the first and second tubular members, 1410 and 1430, may be avoided. Inaddition, during the relative rotation of the second tubular member with respect to the firsttubular member, required during the threaded coupling of the first and second tubularmembers, the tubular sleeve 1418 provides an indication of to what degree the first andsecond tubular members are threadably coupled. For example, if the tubular sleeve 1418can be easily rotated, that would indicate that the first and second tubular members, 1410and 1430, are not fully threadably coupled and in intimate contact with the internai flange1420 of the tubular sleeve. Furthermore, the tubular sleeve 1418 may prevent crackpropagation during the radial expansion and plastic deformation of the first and secondtubular members, 1410 and 1430. In this manner, failure modes such as, for example,longitudinal cracks in the end portions, 1414 and 1428, of the first and second tubularmembers may be limited in severity or eliminated ail together. In addition, after completingthe radial expansion and plastic deformation of the first and second tubular members, 1410and 1430, the tubular sleeve 1418 may provide a fluid tight metal-to-metal seal between theexterior surface of the tubular sleeve and the interior surfaces of the end portions, 1414 and1428, of the first and second tubular members. In this manner, fluidic materials areprevented from passing through the threaded connections, 1412 and 1426, of the first andsecond tubular members, 1410 and 1430, into the annulus between the first and secondtubular members and the structure 32. Furthermore, because, following the radial expansionand plastic deformation of the first and second tubular members, 1410 and 1430, the tubularsleeve 1418 may be maintained in circumferential compression and the end portions, 1414and 1428, of the first and second tubular members, 1410 and 1430, may be maintained incircumferential tension, axial loads and/or torque loads may be transmitted through thetubular sleeve.

[00155] Referring to Fig. 13a, an end of a first tubular member 1510 is positionedwithin and coupled to an end of a tubular sleeve 1512 having an internai flange 1514. In anexemplary embodiment, the end of the first tubular member 1510 abuts one side of theinternai flange 1514. As illustrated in Fig. 13b, an end of second tubular member 1516 isthen positioned within and coupled to another end of the tubular sleeve 1512. In anexemplary embodiment, the end of the second tubular member 1516 abuts another side ofthe internai flange 1514. In an exemplary embodiment, the tubular sleeve 1512 is coupled tothe ends of the first and second tubular members, 1510 and 1516, by expanding the tubular 33 012849 sleeve 1512 tising heat and then inserting the ends of the first and second tubular members into the expanded tubular sleeve 1512. After cooling the tubular sleeve 1512, the tubular sleeve is coupled to the ends of the first and second tubular members, 1510 and 1516.

[00156] In an exemplary embodiment, as illustrated in Figs. 13c and 13d, the first and 5 second tubular members, 1510 and 1516, and the tubular sleeve 1512 may then bepositioned within another structure 32 such as, for example, a wellbore, and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1510 and 1516, may be W from top to bottom or from bottom to top.

[00157] In an exemplary embodiment, during the radial expansion and plasticdeformation of the first and second tubular members, 1510 and 1516, the tubular sleeve1512 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1512 may be maintained in circumferential compression and the 15 ends of the first and second tubular members, 1510 and 1516, may be maintained incircumferential compression.

[00158] The use of the tubular sleeve 1512 during (a) the placement of the first andsecond tubular members, 1510 and 1516, in the structure 32 and (b) the radial expansionand plastic deformation of the first and second tubular members provides a number of 20 significant benefits. For example, the tubular sleeve 1512 may prevent crack propagationduring the radial expansion and plastic deformation of the first and second tubular members,1510 and 1516. In this manner, failure modes such as, for example, longitudinal cracks inthe ends of the first and second tubular members, 1510 and 1516, may be limited in severityor eliminated ail together. In addition, after completing the radial expansion and plastic •£•5 deformation of the first and second tubular members, 1510 and 1516, the tubular sleeve1512 may provide a fluid tight metal-to-metal seal between the exterior surface of the tubularsleeve and the interior surfaces of the end of the first and second tubular members.Furthermore, because, following the radial expansion and plastic deformation of the first andsecond tubular members, 1510 and 1516, the tubular sleeve 1512 may be maintained in 30 circumferential tension and the ends of the first and second tubular members, 1510 and1516, may be maintained in circumferential compression, axial loads and/or torque loadsmay be transmitted through the tubular sleeve.

[00159] Referring to Fig. 14a, a first tubular member 1610 includes a résilient retainingring 1612 mounted within an annular recess 1614. As illustrated in Fig. 14b, the end of the 35 first tubular member 1610 is then inserted into and coupled to an end of a tubular sleeve1616 including an internai flange 1618 and annular recesses, 1620 and 1622, positioned onopposite sides of the internai flange, tapered portions, 1624 and 1626, on one end of the 34 012849 tubular sleeve, and tapered portions, 1628 and 1630, on the other end of the tubular sleeve.

In an exemplary embodiment, the résilient retaining ring 1612 is thereby positioned at least partially in the annular recesses, 1614 and 1620, thereby coupling the first tubular member 1610 to the tubular sleeve 1616, and the end of the first tubular member 1610 abuts one side 5 of the internai flange 1618. During the coupling of the first tubular member 1610 to thetubular sleeve 1616, the tapered portion 1630 facilitâtes the radial compression of therésilient retaining ring 1612 during the insertion of the first tubular member into the tubularsleeve.

[00160] As illustrated in Fig. 14c, an end of a second tubular member 1632 thatincludes a résilient retaining ring 1634 mounted within an annular recess 1636 is theninserted into and coupled to anotherend of the tubular sleeve 1616. In an exemplaryembodiment, the résilient retaining ring 1634 is thereby positioned at least partially in theannular recesses, 1636 and 1622, thereby coupling the second tubular member 1632 to thetubular sleeve 1616, and the end of the second tubular member 1632 abuts another side of 15 the internai flange 1618. During the coupling of the second tubular member 1632 to thetubular sleeve 1616, the tapered portion 1626 facilitâtes the radial compression of therésilient retaining ring 1634 during the insertion of the second tubular member into thetubular sleeve.

[00161] In an exemplary embodiment, as illustrated in Figs. 14d and 14e, the first and 20 second tubular members, 1610 and 1632, and the tubular sleeve 1616 maythen bepositioned within another structure 32 such as, for example, a wellbore, and radiallyexpanded and plastically deformed, for example, by moving an expansion cône 34 throughthe interiors of the first and second tubular members. The movement of the expansion cône34 through the interiors of the first and second tubular members, 1610 and 1632, may be 25 from top to bottom or from bottom to top.

[00162] In an exemplary embodiment, during the radial expansion and plasticdeformation of the first and second tubular members, 1610 and 1632, the tubular sleeve1616 is also radially expanded and plastically deformed. In an exemplary embodiment, as aresuit, the tubular sleeve 1616 may be maintained in circumferential compression and theends of the first and second tubular members, 1610 and 1632, may be maintained incircumferential compression.

[00163] The use of the tubular sleeve 1616 during (a the placement of the first andsecond tubular members, 1610 and 1632, in the structure 32, and (c) the radial expansionand plastic deformation of the first and second tubular members provides a number of 35 significant benefits. For example, the tubular sleeve 1616 protects the exterior surfaces ofthe ends of the first and second tubular members, 1610 and 1632, during handling andinsertion of the tubular members within the structure 32. In this manner, damage to the 35 012849 exterior surfaces of the ends of the first and second tubular member, 1610 and 1632, are prevented that could resuit in stress concentrations that could resuit in a catastrophic failure during subséquent radial expansion operations. Furthermore, the tubular sleeve 1616 may prevent crack propagation during the radial expansion and plastic deformation of the first and 5 second tubular members, 1610 and 1632. In this manner, failure modes such as, for example, longitudinal cracks in the ends of the first and second tubular members, 1610 and1632, may be limited in severity or eliminated ail together. In addition, after completing theradial expansion and plastic deformation of the first and second tubular members, 1610 and1632, the tubular sleeve 1616 may provide a fluid tight metal-to-metal seal between interior 10 surface of the tubular sleeve and the exterior surfaces of the ends of the first and secondtubular members. Furthermore, because, following the radial expansion and plasticdeformation of the first and second tubular members, 1610 and 1632, the tubular sleeve1616 may be maintained in circumferential tension and the ends of the first and secondtubular members, 1610 and 1632, may be maintained in circumferential compression, axial 15 loads and/or torque loads may be transmitted through the tubular sleeve.
