Detailed Description of the Illustrative Embodiments [00154] Referring initially to Fig. 1, an exemplary embodiment of an expandable tubular assembly 10 includes a first expandable tubular member 12 coupled to a second expandable tubular member 14. In several exemplary embodiments, the ends of the first and second expandable tubular members, 12 and 14, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first expandable tubular member 12 has a plastic yield point YP1, and the second expandable tubular member 14 has a plastic yield point YP2. In an exemplary embodiment, the expandable tubular assembly 10 is positioned within a preexisting structure such as, for example, a wellbore 16 that traverses a subterranean formation 18.
[00155] As illustrated in Fig. 2, an expansion device 20 may then be positioned within the second expandable tubular member 14. In several exemplary embodiments, the expansion device 20 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 20 is positioned within the second expandable tubular member 14 before, during, or after the placement of the expandable tubular assembly 10 within the preexisting structure 16.
[00156] As illustrated in Fig. 3, the expansion device 20 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 14 to form a bell-shaped section.
[00157] As illustrated in Fig. 4, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 14 and at least a portion of the first expandable tubular member 12.
[00158] In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 12 and 14, are radially expanded into intimate contact with the interior surface of the preexisting structure 16.
(001591 In an exemplary embodiment, as illustrated in Fig. 5, the plastic yield point YP1 is greater than the plastic yield point VP2. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand the second expandable tubular member 14 is less than the amount of power and/or energy required to radially expand the first expandable tubular member 12.
[00160] In an exemplary embodiment, as illustrated in Fig. 6, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility OPE and a yield strength YSPE prior to radial expansion and plastic deformation, and a ductility DAE and a yield strength YSAE after radial expansion and plastic deformation. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YSPE. In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YSAE is greater than YSPE, the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process.
(00161] In an exemplary embodiment, as illustrated in Fig. 7, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 10 described above with reference to Figs. 1-4, at least a portion of the second expandable tubular member 14 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 12. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 14. Another expandable tubular assembly 22 that includes a first expandable tubular member 24 and a second expandable tubular member 26 may then be positioned in overlapping relation to the first expandable tubular assembly 10 and radially expanded and plastically deformed using the methods described above with reference to Figs. 1-4. Furthermore, following the completion of the radial expansion and plastic deformation of the expandable tubular assembly 20, in an exemplary embodiment, at least a portion of the second expandable tubular member 26 has an inside diameter that is greater than at least the inside diameter of the first expandable tubular member 24. In this manner a bell-shaped section is formed using at least a portion of the second expandable tubular member 26. Furthermore, in this manner, a mono-diameter tubular assembly is formed that defines an internal passage 28 having a substantially constant cross-sectional area and/or inside diameter.
[00162] Referring to Fig. 8, an exemplary embodiment of an expandable tubular assembly includes a first expandable tubular member 102 coupled to a tubular coupling 104. The tubular coupling 104 is coupled to a tubular coupling 106. The tubular coupling 106 is coupled to a second expandable tubular member 108. In several exemplary embodiments, the tubular couplings, 104 and 106, provide a tubular coupling assembly for coupling the first and second expandable tubular members, 102 and 108, together that may include, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, the first and second expandable tubular members 12 have a plastic yield point YP1, and the tubular couplings, 104 and 106, have a plastic yield point YP2. In an exemplary embodiment, the expandable tubular assembly 100 is positioned within a preexisting structure such as, for example, a wellbore 110 that traverses a subterranean formation 112.
[00163] As illustrated in Fig. 9, an expansion device 114 may then be positioned within the second expandable tubular member 108. In several exemplary embodiments, the expansion device 114 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 114 is positioned within the second expandable tubular member 108 before, during, or after the placement of the expandable tubular assembly 100 within the preexisting structure 110.
[00164] As illustrated in Fig. 10, the expansion device 114 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 108 to form a bell-shaped section.
(00165] As illustrated in Fig. 11, the expansion device 114 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 108, the tubular couplings, 104 and 106, and at least a portion of the first expandable tubular member 102.
[00166] In an exemplary embodiment, at least a portion of at least a portion of at least one of the first and second expandable tubular members, 102 and 108, are radially expanded into intimate contact with the interior surface of the preexisting structure 110.
[00167] In an exemplary embodiment, as illustrated in Fig. 12, theplastic yield point VP1 is less than the plastic yield point YP2. In this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and second expandable tubular members, 102 and 108, is less than the amount of power and/or energy required to radially expand each unit length of the tubular couplings, 104 and 106.
[001681 In an exemplary embodiment, as illustrated in Fig. 13, the first expandable tubular member 12 and/or the second expandable tubular member 14 have a ductility OPE and a yield strength YSPE prior to radial expansion and plastic deformation, and a ductility DAE and a yield strength YSAE after radial expansion and plastic deformation. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YSPE. In this manner, the first expandable tubular member 12 and/or the second expandable tubular member 14 are transformed during the radial expansion and plastic deformation process. Furthermore, in this manner, in an exemplary embodiment, the amount of power and/or energy required to radially expand each unit length of the first and/or second expandable tubular members, 12 and 14, is reduced. Furthermore, because the YSAE is greater than YSPE, the collapse strength of the first expandable tubular member 12 and/or the second expandable tubular member 14 is increased after the radial expansion and plastic deformation process.
(00169] Referring to Fig. 14, an exemplary embodiment of an expandable tubular assembly 200 includes a first expandable tubular member 202 coupled to a second expandable tubular member 204 that defines radial openings 204a, 204b, 204c, and 204d.
In several exemplary embodiments, the ends of the first and second expandable tubular members, 202 and 204, are coupled using, for example, a conventional mechanical coupling, a welded connection, a brazed connection, a threaded connection, and/or an interference fit connection. In an exemplary embodiment, one or more of the radial openings, 204a, 204b, 204c, and 204d, have circular, oval, square, and/or irregular cross sections and/or include portions that extend to and interrupt either end of the second expandable tubular member 204. In an exemplary embodiment, the expandable tubular assembly 200 is positioned within a preexisting structure such as, for example, a wellbore 206 that traverses a subterranean formation 208. - [00170] As illustrated in Fig. 15, an expansion device 210 may then be positioned within the second expandable tubular member 204. In several exemplary embodiments, the expansion device 210 may include, for example, one or more of the following conventional expansion devices: a) an expansion cone; b) a rotary expansion device; c) a hydroforming expansion device; d) an impulsive force expansion device; d) any one of the expansion devices commercially available from, or disclosed in any of the published patent applications or issued patents, of Weatherford International, Baker Hughes, Halliburton Energy Services, Shell Oil Co., Schlumberger, and/or Enventure Global Technology L.L.C. In several exemplary embodiments, the expansion device 210 is positioned within the second expandable tubular member 204 before, during, or after the placement of the expandable tubular assembly 200 within the preexisting structure 206.
[00171] As illustrated in Fig. 16, the expansion device 210 may then be operated to radially expand and plastically deform at least a portion of the second expandable tubular member 204 to form a bell-shaped section.
(00172] As illustrated in Fig. 16, the expansion device 20 may then be operated to radially expand and plastically deform the remaining portion of the second expandable tubular member 204 and at least a portion of the first expandable tubular member 202.
[00173] In an exemplary embodiment, the anisotropy ratio AR for the first and second expandable tubular members is defined by the following equation: AR = In (WT/1NT0)/ln (D/D0); where AR = anisotropy ratio; where WT = final wall thickness of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member; where WT1 = initial wall thickness of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member; where D, = final inside diameter of the expandable tubular member following the radial expansion and plastic deformation of the expandable tubular member; and where D = initial inside diameter of the expandable tubular member prior to the radial expansion and plastic deformation of the expandable tubular member.
[00174] In an exemplary embodiment, the anisotropy ratio AR for the first and/or second expandable tubular members, 204 and 204, is greater than 1.
[00175] In an exemplary experimental embodiment, the second expandable tubular member 204 had an anisotropy ratio AR greater than 1, and the radial expansion and plastic deformation of the second expandable tubular member did not result in any of the openings, 204a, 204b, 204c, and 204d, splitting or otherwise fracturing the remaining portions of the second expandable tubular member. This was an unexpected result.
[00176] Referring to Fig. 18, in an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 are processed using a method 300 in which a tubular member in an initial state is thermo-mechanically processed in step 302. In an exemplary embodiment, the thermo-mechanical processing 302 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo-mechanical processing 302, the tubular member is transformed to an intermediate state.
The tubular member is then further thermo-mechanically processed in step 304. In an exemplary embodiment, the thermo-mechanical processing 304 includes one or more heat treating and/or mechanical forming processes. As a result, of the thermo-mechanical processing 304, the tubular member is transformed to a final state.
[00177] In an exemplary embodiment, as illustrated in Fig. 19, during the operation of the method 300, the tubular member has a ductility PE and a yield strength YSPE prior to the final thermo-mechanical processing in step 304, and a ductility DAE and a yield strength YSAE after final thermo-mechanical processing. In an exemplary embodiment, DPE is greater than DAE, and YSAE is greater than YS. In this manner, the amount of energy and/or power required to transform the tubular member, using mechanical forming processes, during the final thermo-mechanical processing in step 304 is reduced. Furthermore, in this manner, because the YSAE is greater than YSPE, the collapse strength of the tubular member is increased after the final thermo-mechanical processing in step 304.
[00178] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, have the following characteristics: Characteristic Value Tensile Strength 60 to 120 ksi Yield Strength 50 to 100 ksi V/I Ratio Maximum of 50/85 % Elongation During Radial Expansion and Minimum of 35 % Plastic Deformation Width Reduction During Radial Expansion Minimum of 40 % and Plastic Deformation Wall Thickness Reduction During Radial Minimum of 30 % Expansion and Plastic Deformation Anisotropy Minimum of 1.5 Minimum Absorbed Energy at -4 F (-20 C) in 80 ft-lb the Longitudinal Direction Minimum Absorbed Energy at -4 F (-20 C) in 60 ft-lb the Transverse Direction Minimum Absorbed Energy at -4 F (-20 C) 60 ft-lb Transverse To A Weld Area Flare Expansion Testing Minimum of 75% Without A Failure Increase in Yield Strength Due To Radial Greater than 5.4 % Expansion and Plastic Deformation [00179] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are characterized by an expandability coefficient 1: i. f=rXn ii. where f = expandability coefficient; 1. r = anisotropy coefficient; and 2. n = strain hardening exponent.
[00180] In an exemplary embodiment, the anisotropy coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 1. In an exemplary embodiment, the strain hardening exponent for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12. In an exemplary embodiment, the expandability coefficient for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is greater than 0.12.
[00181] In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy to radially expand and plastically deform each unit length than a tubular member having a lower expandability coefficient. In an exemplary embodiment, a tubular member having a higher expandability coefficient requires less power and/or energy per unit length to radially expand and plastically deform than a tubular member having a lower expandability coefficient.
[00182] In several exemplary experimental embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are steel alloys having one of the following compositions: Element and Percentage By Weight Steel C Mn P S Si Cu Ni Cr Alloy A 0.065 1.44 0.01 0.002 0.24 0.01 0.01 0.02 B 0.18 1.28 0.017 0.004 0.29 0.01 0.01 0.03 C 0.08 0.82 0.006 0.003 0.30 0.16 0.05 0.05 D 0.02 1.31 0.02 0.001 0.45 -9.1 18.7 [00183] In exemplary experimental embodiment, as illustrated in Fig. 20, a sample of an expandable tubular member composed of Alloy A exhibited a yield point before radial expansion and plastic deformation YPBE, a yield point after radial expansion and plastic deformation of about 16 % YPAE16%, and a yield point after radial expansion and plastic deformation of about 24 % YPA4%. In an exemplary experimental embodiment, YPAE24% > YPAE16%> YPBE. Furthermore, in an exemplary experimental embodiment, the ductility of the sample of the expandable tubular member composed of Alloy A also exhibited a higher ductility prior to radial expansion and plastic deformation than after radial expansion and plastic deformation. These were unexpected results.
[00184] In an exemplary experimental embodiment, a sample of an expandable tubular member composed of Alloy A exhibited the following tensile characteristics before and after radial expansion and plastic deformation: Yield Yield Elongation Width Wall Anisotropy Point Ratio % Reduction Thickness ksi % Reduction % Before 46.9 0.69 53 -52 55 0.93 Radial Expansion and Plastic Deformation After 16% 65.9 0.83 17 42 51 0. 78 Radial Expansion After 24% 68.5 0.83 5 44 54 0.76 Radial Expansion % Increase 40% for 16% radial expansion 46% for 24% radial expansion [00185] In exemplary experimental embodiment, as illustrated in Fig. 21, a sample of an expandable tubular member composed of Alloy B exhibited a yield point before radial expansion and plastic deformation YPBE, a yield point after radial expansion and plastic deformation of about 16 % YPAE16%, and a yield point after radial expansion and plastic deformation of about 24 % YPAE24%. In an exemplary embodiment, YPAE24% > YPAE16% > YPBE. Furthermore, in an exemplary experimental embodiment, the ductility of the sample of the expandable tubular member composed of Alloy B also exhibited a higher ductility prior to radial expansion and plastic deformation than after radial expansion and plastic deformation.
These were unexpected results.
(00186) In an exemplary experimental embodiment, a sample of an expandable tubular member composed of Alloy B exhibited the following tensile characteristics before and after radial expansion and plastic deformation: Yield Yield Elongation Width Wall Anisotropy Point Ratio % Reduction Thickness ksi % Reduction % Before 57.8 0.71 44 43 46 0.93 Radial Expansion and Plastic Deformation After 16% 74.4 0.84 16 38 42 0. 87 Radial Expansion After 24% 79.8 0.86 20 36 42 0.81 Radial Expansion % Increase 28.7% increase for 16% radial expansion 38% increase for 24% radial expansion [00187) In an exemplary experimental embodiment, samples of expandable tubulars composed of Alloys A, B, C, and D exhibited the following tensile characteristics prior to radial expansion and plastic deformation: Steel Yield Yield Elongation Anisotropy Absorbed Expandability Alloy ksi Ratio % Energy Coefficient ft-lb A 47.6 0.71 44 1.48 145 B 57.8 0.71 44 1.04 62.2 C 61.7 0.80 39 1.92 268 D 48 0.55 56 1.34 - [00188] In an exemplary embodiment, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 have a strain hardening exponent greater than 0.12, and a yield ratio is less than 0.85.
[00189] In an exemplary embodiment, the carbon equivalent Ce, for tubular members having a carbon content (by weight percentage) less than or equal to 0.12%, is given by the following expression: Ce =C+Mn16+(Cr+Mo+V+Ti+Nb)/5+(Ni+Cu)/15 where Ce = carbon equivalent value; a. C = carbon percentage by weight; b. Mn = manganese percentage by weight; c. Cr = chromium percentage by weight; d. Mo = molybdenum percentage by weight; e. V = vanadium percentage by weight; f. Ti = titanium percentage by weight; g. Nb = niobium percentage by weight; h. Ni = nickel percentage by weight; and i. Cu = copper percentage by weight.
[00190] In an exemplary embodiment, the carbon equivalent value Ce, for tubular members having a carbon content less than or equal to 0.12% (by weight), for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is less than 0.21.
(00191] In an exemplary embodiment, the carbon equivalent C0, for tubular members having more than 0.12% carbon content (by weight), is given by the following expression: Ce =C+Si/30+(Mn+Cu+Cr)/20+Ni/60+Mo/15+V/10+5*B where Ce = carbon equivalent value; a. C = carbon percentage by weight; b. Si = silicon percentage by weight: c. Mn = manganese percentage by weight; d. Cu = copper percentage by weight; e. Cr = chromium percentage by weight; f. Ni = nickel percentage by weight; g. Mo = molybdenum percentage by weight; h. V = vanadium percentage by weight; and I. B = boron percentage by weight.
[00192] In an exemplary embodiment, the carbon equivalent value Ce, for tubular members having greater than 0.12% carbon content (by weight), for one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 is less than 0.36.
[00193] Referring to Fig. 22 in an exemplary embodiment, a first tubular member 2210 includes an internally threaded connection 2212 at an end portion 2214. A first end of a tubular sleeve 2216 that includes an internal flange 2218 having a tapered portion 2220, and a second end that includes a tapered portion 2222, is then mounted upon and receives the end portion 2214 of the first tubular member 2210. In an exemplary embodiment, the end portion 2214 of the first tubular member 2210 abuts one side of the internal flange 2218 of the tubular sleeve 2216, and the internal diameter of the internal flange 2218 of the tubular sleeve 2216 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 2212 of the end portion 2214 of the first tubular member 2210. An externally threaded connection 2224 of an end portion 2226 of a second tubular member 2228 having an annular recess 2230 is then positioned within the tubular sleeve 2216 and threadably coupled to the internally threaded connection 2212 of the end portion 2214 of the first tubular member 2210. In an exemplary embodiment, the internal flange 2218 of the tubular sleeve 2216 mates with and is received within the annular recess 2230 of the end portion 2226 of the second tubular member 2228. Thus, the tubular sleeve 2216 is coupled to and surrounds the external surfaces of the first and second tubular members, 2210 and 2228.
[00194] The internally threaded connection 2212 of the end portion 2214 of the first tubular member 2210 is a box connection, and the externally threaded connection 2224 of the end portion 2226 of the second tubular member 2228 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2216 is at least approximately.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.
[00195] As illustrated in Fig. 22, the first and second tubular members, 2210 and 2228, and the tubular sleeve 2216 may be positioned within another structure 2232 such as, for example, a cased or uncased weilbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device 2234 within and/or through the interiors of the first and second tubular members. The tapered portions, 2220 and 2222, of the tubular sleeve 2216 facilitate the insertion and movement of the first and second tubular members within and through the structure 2232, and the movement of the expansion 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.
[00196] During the radiat 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, the tubular 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.
[00197] Sleeve 2216 increases the axial compression loading of the connection between tubular members 2210 and 2228 before and after expansion by the expansion device 2234. Sleeve 2216 may, for example, be secured to tubular members 2210 and 2228 by a heat shrink fit.
[00198] 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.
[00199] The use of the tubular sleeve 2216 during (a) the coupling of the first tubular member 2210 to the second tubular member 2228, (b) the placement of the first and second tubular members in the structure 2232, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular 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 the structure 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, the tubular sleeve 2216 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 2228 to the first 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, the tubular sleeve 2216 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular 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 the internal flange 2218 of the tubular sleeve. Furthermore, the tubular 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, the tubular sleeve 2216 may provide a fluid tight metal-to-metal seal between interior surface of the tubular 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 the structure 2232. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 2210 and 2228, the tubular 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.
[00200] 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 the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
(00201] Referring to Fig. 23, in an exemplary embodiment, a first tubular member 210 includes an internally threaded connection 2312 at an end portion 2314. A first end of a tubular sleeve 2316 includes an internal flange 2318 and a tapered portion 2320. A second end of the sleeve 2316 includes an internal flange 2321 and a tapered portion 2322. An externally threaded connection 2324 of an end portion 2326 of a second tubular member 2328 having an annular recess 2330, is then positioned within the tubular sleeve 2316 and threadably coupled to the internally threaded connection 2312 of the end portion 2314 of the first tubular member 2310. The internal flange 2318 of the sleeve 2316 mates with and is received within the annular recess 2330.
[00202] The first tubular member 2310 includes a recess 2331. The internal flange 2321 mates with and is received within the annular recess 2331. Thus, the sleeve 2316 is coupled to and surrounds the external surfaces of the first and second tubular members 2310 and 2328.
[00203] The internally threaded connection 2312 of the end portion 2314 of the first tubular member 2310 is a box connection, and the externally threaded connection 2324 of the end portion 2326 of the second tubular member 2328 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2316 is at least approximately.020" greater than the outside diameters of the first and second tubular members 2310 and 2328. In this manner, during the threaded coupling of the first and second tubular members 2310 and 2328, fluidic materials within the first and second tubular members may be vented from the tubular members.
[00204] As illustrated in Fig. 23, the first and second tubular members 2310 and 2328, and the tubular sleeve 2316 may then be positioned within another structure 2332 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2334 through and/or within the interiors of the first and second tubular members. The tapered portions 2320 and 2322, of the tubular sleeve 2316 facilitates the insertion and movement of the first and second tubular members within and through the structure 2332, and the displacement of the expansion device 2334 through the interiors of the first and second tubular members 2310 and 2328, may be from top to bottom or from bottom to top.
[00205] During the radial expansion and plastic deformation of the first and second tubular members 2310 and 2328, the tubular sleeve 2316 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2316 may be maintained in circumferential tension and the end portions 2314 and 2326, of the first and second tubular members 2310 and 2328, may be maintained in circumferential compression.
[00206] Sleeve 2316 increases the axial tension loading of the connection between tubular members 2310 and 2328 before and after expansion by the expansion device 2334.
Sleeve 2316 may be secured to tubular members 2310 and 2328 by a heat shrink fit.
[00207] In several exemplary embodiments, one or more portions of the first and second tubular members, 2310 and 2328, and the tubular sleeve 2316 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00208] Referring to Fig. 24, in an exemplary embodiment, a first tubular member 2410 includes an internally threaded connection 2412 at an end portion 2414. A first end of a tubular sleeve 2416 includes an internal flange 2418 and a tapered portion 2420. A second end of the sleeve 2416 includes an internal flange 2421 and a tapered portion 2422.
An externally threaded connection 2424 of an end portion 2426 of a second tubular member 2428 having an annular recess 2430, is then positioned within the tubular sleeve 2416 and threadably coupled to the internally threaded connection 2412 of the end portion 2414 of the first tubular member 2410. The internal flange 2418 of the sleeve 2416 mates with and is received within the annular recess 2430. The first tubular member 2410 includes a recess 2431. The internal flange 2421 mates with and is received within the annular recess 2431.
Thus, the sleeve 2416 is coupled to and surrounds the external surfaces of the first and second tubular members 2410 and 2428.
[00209] The internally threaded connection 2412 of the end portion 2414 of the first tubular member 2410 is a box connection, and the externally threaded connection 2424 of the end portion 2426 of the second tubular member 2428 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2416 is at least approximately.020" greater than the outside diameters of the first and second tubular members 2410 and 2428. In this manner, during the threaded coupling of the first and second tubular members 2410 and 2428, fluidic materials within the first and second tubular members may be vented from the tubular members.
[00210] As illustrated in Fig. 24, the first and second tubular members 2410 and 2428, and the tubular sleeve 2416 may then be positioned within another structure 2432 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2434 through and/or within the interiors of the first and second tubular members. The tapered portions 2420 and 2422, of the tubular sleeve 2416 facilitate the insertion and movement of the first and second tubular members within and through the structure 2432, and the displacement of the expansion device 2434 through the interiors of the first and second tubular members, 2410 and 2428, may be from top to bottom or from bottom to top.
[00211] During the radial expansion and plastic deformation of the first and second tubular members, 2410 and 2428, the tubular sleeve 2416 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2416 may be maintained incircumferential tension and the end portions, 2414 and 2426, of the first and second tubular members, 2410 and 2428, may be maintained in circumferential compression.
[00212] The sleeve 2416 increases the axial compression and tension loading of the connection between tubular members 2410 and 2428 before and after expansion by expansion device 2424. Sleeve 2416 may be secured to tubular members 2410 and 2428 by a heat shrink fit.
[00213] In several exemplary embodiments, one or more portions of the first and second tubular members, 2410 and 2428, and the tubular sleeve 2416 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
(00214] Referring to Fig. 25, in an exemplary embodiment, a first tubular member 2510 includes an internally threaded connection 2512 at an end portion 2514. A first end of a tubular sleeve 2516 includes an internal flange 2518 and a relief 2520. A second end of the sleeve 2516 includes an internal flange 2521 and a relief 2522. An externally threaded connection 2524 of an end portion 2526 of a second tubular member 2528 having an annular recess 2530, is then positioned within the tubular sleeve 2516 and threadably coupled to the internally threaded connection 2512 of the end portion 2514 of the first tubular member 2510. The internal flange 2518 of the sleeve 2516 mates with and is received within the annular recess 2530. The first tubular member 2510 includes a recess 2531. The internal flange 2521 mates with and is received within the annular recess 2531. Thus, the sleeve 2516 is coupled to and surrounds the external surfaces of the first and second tubular members 2510 and 2528.
(00215] The internally threaded connection 2512 of the end portion 2514 of the first tubular member 2510 is a box connection, and the externally threaded connection 2524 of the end portion 2526 of the second tubular member 2528 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2516 is at least approximately.020" greater than the outside diameters of the first and second tubular members 2510 and 2528. In this manner, during the threaded coupling of the first and second tubular members 2510 and 2528, fluidic materials within the first and second tubular members may be vented from the tubular members.
(00216] As illustrated in Fig. 25, the first and second tubular members 2510 and 2528, and the tubular sleeve 2516 may then be positioned within another structure 2532 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2534 through and/or within the interiors of the first and second tubular members. The reliefs 2520 and 2522 are each filled with a sacrificial material 2540 including a tapered surface 2542 and 2544, respectively. The material 2540 may be a metal or a synthetic, and is provided to facilitate the insertion and movement of the first and second tubular members 2510 and 2528, through the structure 2532. The displacement of the expansion device 2534 through the interiors of the first and second tubular members 2510 and 2528, may, for example, be from top to bottom or from bottom to top.
[00217] During the radial expansion and plastic deformation of the first and second tubular members 2510 and 2528, the tubular sleeve 2516 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2516 may be maintained in circumferential tension and the end portions 2514 and 2526, of the first and second tubular members, 2510 and 2528, may be maintained in circumferential compression.
(002181 The addition of the sacrificial material 2540, provided on sleeve 2516, avoids stress risers on the sleeve 2516 and the tubular member 2510. The tapered surfaces 2542 and 2544 are intended to wear or even become damaged, thus incurring such wear or damage which would otherwise be borne by sleeve 2516. Sleeve 2516 may be secured to tubular members 2510 and 2528 by a heat shrink fit.
[00219] In several exemplary embodiments, one or more portions of the first and second tubular members, 2510 and 2528, and the tubular sleeve 2516 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00220] Referring to Fig. 26, in an exemplary embodiment, a first tubular member 2610 includes an internally threaded connection 2612 at an end portion 2614. A first end of a tubular sleeve 2616 includes an internal flange 2618 and a tapered portion 2620. A second end of the sleeve 2616 includes an internal flange 2621 and a tapered portion 2622.
An externally threaded connection 2624 of an end portion 2626 of a second tubular member 2628 having an annular recess 2630, is then positioned within the tubular sleeve 2616 and threadably coupled to the internally threaded connection 2612 of the end portion 2614 of the first tubular member 2610. The internal flange 2618 of the sleeve 2616 mates with and is received within the annular recess 2630.
[00221] The first tubular member 2610 includes a recess 2631. The internal flange 2621 mates with and is received within the annular recess 2631. Thus, the sleeve 2616 is coupled to and surrounds the external surfaces of the first and second tubular members 2610 and 2628.
[00222] The internally threaded connection 2612 of the end portion 2614 of the first tubular member 2610 is a box connection, and the externally threaded connection 2624 of the end portion 2626 of the second tubular member 2628 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2616 is at least approximately.020" greater than the outside diameters of the first and second tubular members 2610 and 2628. In this manner, during the threaded coupling of the first and second tubular members 2610 and 2628, fluidic materials within the first and second tubular members may be vented from the tubular members.
[00223] As illustrated in Fig. 26, the first and second tubular members 2610 and 2628, and the tubular sleeve 2616 may then be positioned within another structure 2632 such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2634 through and/or within the interiors of the first and second tubular members. The tapered portions 2620 and 2622, of the tubular sleeve 2616 facilitates the insertion and movement of the first and second tubular members within and through the structure 2632, and the displacement of the expansion device 2634 through the interiors of the first and second tubular members 2610 and 2628, may, for example, be from top to bottom or from bottom to top.
(00224] During the radial expansion and plastic deformation of the first and second tubular members 2610 and 2628, the tubular sleeve 2616 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2616 may be maintained in circumferential tension and the end portions 2614 and 2626, of the first and second tubular members 2610 and 2628, may be maintained in circumferential compression.
[00225] Sleeve 2616 is covered by a thin walled cylinder of sacrificial material 2640.
Spaces 2623 and 2624, adjacent tapered portions 2620 and 2622, respectively, are also filled with an excess of the sacrificial material 2640. The material may be a metal or a synthetic, and is provided to facilitate the insertion and movement of the first and second tubular members 2610 and 2628, through the structure 2632.
[00226] The addition of the sacrificial material 2640, provided on sleeve 2616, avoids stress risers on the sleeve 2616 and the tubular member 2610. The excess of the sacrificial material 2640 adjacent tapered portions 2620 and 2622 are intended to wear or even become damaged, thus incurring such wear or damage which would otherwise be borne by sleeve 2616. Sleeve 2616 may be secured to tubular members 2610 and 2628 by a heat shrink fit.
[00227] In several exemplary embodiments, one or more portions of the first and second tubular members, 2610 and 2628, and the tubular sleeve 2616 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00228] Referring to Fig. 27, in an exemplary embodiment, a first tubular member 2710 includes an internally threaded connection 2712 at an end portion 2714. A first end of a tubular sleeve 2716 includes an internal flange 2718 and a tapered portion 2720. A second end of the sleeve 2716 includes an internal flange 2721 and a tapered portion 2722.
An externally threaded connection 2724 of an end portion 2726 of a second tubular member 2728 having an annular recess 2730, is then positioned within the tubular sleeve 2716 and threadably coupled to the internally threaded connection 2712 of the end portion 2714 of the first tubular member 2710. The internal flange 2718 of the sleeve 2716 mates with and is received within the annular recess 2730.
[00229] The first tubular member 2710 includes a recess 2731. The internal flange 2721 mates with and is received within the annular recess 2731. Thus, the sleeve 2716 is coupled to and surrounds the external surfaces of the first and second tubular members 2710 and 2728.
(00230] The internally threaded connection 2712 of the end portion 2714 of the first tubular member 2710 is a box connection, and the externally threaded connection 2724 of the end portion 2726 of the second tubular member 2728 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2716 is at least approximately.020" greater than the outside diameters of the first and second tubular members 2710 and 2728. In this manner, during the threaded coupling of the first and second tubular members 2710 and 2728, fluidic materials within the first and second tubular members may be vented from the tubular members.
[00231] As illustrated in Fig. 27, the first and second tubular members 2710 and 2728, and the tubular sleeve 2716 may then be positioned within another structure 2732 such as, for example, a weUbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device 2734 through and/or within the interiors of the first and second tubular members. The tapered portions 2720 and 2722, of the tubular sleeve 2716 facilitates the insertion and movement of the first and second tubular members within and through the structure 2732, and the displacement of the expansion device 2734 through the interiors of the first and second tubular members 2710 and 2728, may be from top to bottom or from bottom to top.
[00232] During the radial expansion and plastic deformation of the first and second tubular members 2710 and 2728, the tubular sleeve 2716 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2716 may be maintained in circumferential tension and the end portions 2714 and 2726, of the first and second tubular members 2710 and 2728, may be maintained in circumferential compression.
[00233] Sleeve 2716 has a variable thickness due to one or more reduced thickness portions 2790 and/or increased thickness portions 2792.
[00234] Varying the thickness of sleeve 2716 provides the ability to control or induce stresses at selected positions along the length of sleeve 2716 and the end portions 2724 and 2726. Sleeve 2716 may be secured to tubular members 2710 and 2728 by a heat shrink fit.
(00235] In several exemplary embodiments, one or more portions of the first and second tubular members, 2710 and 2728, and the tubular sleeve 2716 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00236] Referring to Fig. 28, in an alternative embodiment, instead of varying the thickness of sleeve 2716, the same result described above with reference to Fig. 27, may be achieved by adding a member 2740 which may be coiled onto the grooves 2739 formed in sleeve 2716, thus varying the thickness along the length of sleeve 2716.
(00237] Referring to Fig. 29, in an exemplary embodiment, a first tubular member 2910 includes an internally threaded connection 2912 and an internal annular recess 2914 at an end portion 2916. A first end of a tubular sleeve 2918 includes an internal flange 2920, and a second end of the sleeve 2916 mates with and receives the end portion 2916 of the first tubular member 2910. An externally threaded connection 2922 of an end portion 2924 of a second tubular member 2926 having an annular recess 2928, is then positioned within the tubular sleeve 2918 and threadably coupled to the internally threaded connection 2912 of the end portion 2916 of the first tubular member 2910. The internal flange 2920 of the sleeve 2918 mates with and is received within the annular recess 2928. A sealing element 2930 is received within the internal annular recess 2914 of the end portion 2916 of the first tubular member 2910.
[00238] The internally threaded connection 2912 of the end portion 2916 of the first tubular member 2910 is a box connection, and the externally threaded connection 2922 of the end portion 2924 of the second tubular member 2926 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 2918 is at least approximately.020" greater than the outside diameters of the first tubular member 2910. In this manner, during the threaded coupling of the first and second tubular members 2910 and 2926, fluidic materials within the first and second tubular members may be vented from the tubular members.
[00239] The first and second tubular members 2910 and 2926, and the tubular sleeve 2918 may be positioned within another structure such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device through and/or within the interiors of the first and second tubular members.
[00240] During the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, the tubular sleeve 2918 is also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 2918 may be maintained in circumferential tension and the end portions 2916 and 2924, of the first and second tubular members 2910 and 2926, respectively, may be maintained in circumferential compression.
[00241] In an exemplary embodiment, before, during, and after the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, and the tubular sleeve 2918, the sealing element 2930 seals the interface between the first and second tubular members. In an exemplary embodiment, during and after the radial expansion and plastic deformation of the first and second tubular members 2910 and 2926, and the tubular sleeve 2918, a metal to metal seal is formed between at least one of: the first and second tubular members 2910 and 2926, the first tubular member and the tubular sleeve 2918, and/or the second tubular member and the tubular sleeve. In an exemplary embodiment, the metal to metal seal is both fluid tight and gas tight.
[002421 In several exemplary embodiments, one or more portions of the first and second tubular members, 2910 and 2926, the tubular sleeve 2918, and the sealing element 2930 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00243] Referring to Fig. 30a, in an exemplary embodiment, a first tubular member 3010 includes internally threaded connections 3012a and 3012b, spaced apart by a cylindrical internal surface 3014, at an end portion 3016.

A sealing element 3026 is received within an annulus defined between the internal cylindrical surface 3014 of the first tubular member 3010 and the external cylindrical surface 3020 of the second tubular member 3024.
[00244] The internally threaded connections, 3012a and 3012b, of the end portion 3016 of the first tubular member 3010 are box connections, and the externally threaded connections, 3018a and 3018b, of the end portion 3022 of the second tubular member 3024 are pin connections.

[00255] Referring to Fig. 30c, in an exemplary embodiment, a first tubular member 3050 includes internally threaded connections 3052a and 3052b, spaced apart by a cylindrical internal surface 3054 including one or more square grooves 3056, at an end portion 3058.

[002651 During the radial expansion and plastic deformation of the first and second tubular members 3110 and 3124, the tubular sleeves 3126, 3128 and/or 3130 are also radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeves 3126, 3128, and/or 3130 are maintained in circumferential tension and the end portions 3116 and 3122, of the first and second tubular members 3110 and 3124, may be maintained in circumferential compression.
[00266] The sleeves 3126, 3128, and/or 3130 may, for example, be secured to the first tubular member 3110 by a heat shrink fit.
[00267] In several exemplary embodiments, one or more portions of the first and second tubular members, 3110 and 3124, and the sleeves, 3126, 3128, and 3130, have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.

As illustrated in Fig. 32b, the tubular sleeve 3222 is then forced into engagement with the external surface of the end portion 3214 of the first tubular member 3210 in a conventional manner. As a result, the end portions, 3214 and 3218, of the first and second tubular members, 3210 and 3220, are upset in an undulating fashion.
(00271] The first and second tubular members 3210 and 3220, and the tubular sleeve 3222, may then be positioned within another structure such as, for example, a wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating an expansion device through and/or within the interiors of the first and second tubular members.
(00272] During the radial expansion and plastic deformation of the first and second tubular members 3210 and 3220, the tubular sleeve 3222 isalso radially expanded and plastically deformed. In an exemplary embodiment, as a result, the tubular sleeve 3222 is maintained in circumferential tension and the end portions 3214 and 3218, of the first and second tubular members 3210 and 3220, may be maintained in circumferential compression.
[00273] In several exemplary embodiments, one or more portions of the first and second tubular members, 3210 and 3220, and the sleeve 3222 have one or more of the material properties of one or more of the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
(00274] Referring to Fig. 33, in an exemplary embodiment, a first tubular member 3310 includes an internally threaded connection 3312 and an annular projection 3314 at an end portion 3316.
(00275] A first end of a tubular sleeve 3318 that includes an internal flange 3320 having a tapered portion 3322 and an annular recess 3324 for receiving the annular projection 3314 of the first tubular member 3310, and a second end that includes a tapered portion 3326, is then mounted upon and receives the end portion 3316 of the first tubular member 3310.
(00276] In an exemplary embodiment, the end portion 3316 of the first tubular member 3310 abuts one side of the internal flange 3320 of the tubular sleeve 3318 and the annular projection 3314 of the end portion of the first tubular member mates with and is received within the annular recess 3324 of the internal flange of the tubular sleeve, and the internal diameter of the internal flange 3320 of the tubular sleeve 3318 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310. An externally threaded connection 3326 of an end portion 3328 of a second tubular member 3330 having an annular recess 3332 is then positioned within the tubular sleeve 3318 and threadably coupled to the internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310. In an exemplary embodiment, the internal flange 3332 of the tubular sleeve 3318 mates with and is received within the annular recess 3332 of the end portion 3328 of the second tubular member 3330. Thus, the tubular sleeve 3318 is coupled to and surrounds the external surfaces of the first and second tubular members, 3310 and 3328.
[00277] The internally threaded connection 3312 of the end portion 3316 of the first tubular member 3310 is a box connection, and the externally threaded connection 3326 of the end portion 3328 of the second tubular member 3330 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 3318 is at least approximately.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.
[00278] As illustrated in Fig. 33, the first and second tubular members, 3310 and 3330, and the tubular sleeve 3318 may be positioned within another structure 3334 such as, for example, a cased or uncased weilbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device 3336 within and/or through the interiors of the first and second tubular members. The tapered portions.
3322 and 3326, of the tubular sleeve 3318 facilitate the insertion and movement of the first and second tubular members within and through the structure 3334, and the movement of the expansion 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.
[002791 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, the tubular 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.
[002801 Sleeve 3316 increases the axial compression loading of the connection between tubular members 3310 and 3330 before and after expansion by the expansion device 3336. Sleeve 3316 may be secured to tubular members 3310 and 3330, for example, by a heat shrink fit.
[00281] 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.
[00282] The use of the tubular sleeve 3318 during (a) the coupling of the first tubular member 3310 to the second tubular member 3330, (b) the placement of the first and second tubular members in the structure 3334, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular 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 the structure 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, the tubular sleeve 3318 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 3330 to the first 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, the tubular sleeve 3318 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular 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 the internal flange 3320 of the tubular sleeve. Furthermore, the tubular 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, the tubular sleeve 3318 may provide a fluid tight metal-to-metal seal between interior surface of the tubular 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 the structure 3334. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 3310 and 3330, the tubular 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.
[00283] 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 the tubular members 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204.
[00284] Referring to Figs. 34a, 34b, and 34c, in an exemplary embodiment, a first tubular member 3410 includes an internally threaded connection 1312 and one or more external grooves 3414 at an end portion 3416.
[00285] A first end of a tubular sleeve 3418 that includes an internal flange 3420 and a tapered portion 3422, a second end that includes a tapered portion 3424, and an intermediate portion that includes one or more longitudinally aligned openings 3426, is then mounted upon and receives the end portion 3416 of the first tubular member 3410.
[00286] In an exemplary embodiment, the end portion 3416 of the first tubular member 3410 abuts one side of the internal flange 3420 of the tubular sleeve 3418, and the internal diameter of the internal flange 3420 of the tubular sleeve 3416 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 3412 of the end portion 3416 of the first tubular member 3410. An externally threaded connection 3428 of an end portion 3430 of a second tubular member 3432 that includes one or more internal grooves 3434 is then positioned within the tubular sleeve 3418 and threadably coupled to the internally threaded connection 3412 of the end portion 3416 of the first tubular member 3410. In an exemplary embodiment, the internal flange 3420 of the tubular sleeve 3418 mates with and is received within an annular recess 3436 defined in the end portion 3430 of the second tubular member 3432. Thus, the tubular sleeve 3418 is coupled to and surrounds the external surfaces of the first and second tubular members, 3410 and 3432.
[00287] 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 the tubular 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.
[00288] 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, 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.
[00289] 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.
[00290] 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 the openings 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 the grooves 3414 and/or 3434 and the openings 3426 are orthogonal to one another. In an exemplary embodiment, the grooves 3414 and/or 3434 are helical grooves.
[00291] 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.
[002921 The use of the 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. For example, 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. In this manner, damage to the exterior surfaces of the end portions, 3416 and 3430, of the first and second tubular members, 3410 and 3432, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, the 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. 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, 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.

In addition, after completing 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. In this manner, fluidic materials are prevented from passing through the threaded connections, 3412 and 3430, of the first and second tubular members, 3410 and 3432, into the annulus between the first and second tubular members and the structure. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 3410 and 3432, 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, axial loads and/or torque loads may be transmitted through the tubular sleeve.
(002931 In several exemplary embodiments, the first and second tubular members described above with reference to Figs. 1 to 34c are radially expanded and plastically deformed using the expansion device in a conventional manner and/or using one or more of the methods and apparatus disclosed in one or more of the following: The present application is related to the following: (1) U.S. patent application serial no. 09/454,139, attorney docket no. 25791.03.02, filed on 1213/1999, (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. 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 11115/1999, (5) U.S. patent application 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 on 2/24/2000, (7) u.s. patent application serial no. 09/511,941, attorney docket no. 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) PCI patent application serial no.

[00294] Referring to Fig. 35a an exemplary embodiment of an expandable tubular member 3500 includes a first tubular region 3502 and a second tubular portion 3504. In an exemplary embodiment, the material properties of the first and second tubular regions, 3502 and 3504, are different. In an exemplary embodiment, the yield points of the first and second tubular regions, 3502 and 3504, are different. In an exemplary embodiment, the yield point of the first tubular region 3502 is less than the yield point of the second tubular region 3504. In several exemplary embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204 incorporate the tubular member 3500.
[002951 Referring to Fig. 35b, in an exemplary embodiment, the yield point within the first and second tubular regions, 3502a and 3502b, of the expandable tubular member 3502 vary as a function of the radial position within the expandable tubular member. In an exemplary embodiment, the yield point increases as a function of the radial position within the expandable tubular member 3502. In an exemplary embodiment, the relationship between the yield point and the radial position within the expandable tubular member 3502 is a linear relationship. In an exemplary embodiment, the relationship between the yield point and the radial position within the expandable tubular member 3502 is a non-linear relationship. In an exemplary embodiment, the yield point increases at different rates within the first and second tubular regions, 3502a and 3502b, as a function of the radial position within the expandable tubular member 3502. In an exemplary embodiment, the functional relationship, and value, of the yield points within the first and second tubular regions, 3502a and 3502b, of the expandable tubular member 3502 are modified by the radial expansion and plastic deformation of the expandable tubular member.
(00296] In several exemplary embodiments, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202, 204 and/or 3502, prior to a radial expansion and plastic deformation, include a microstructure that is a combination of a hard phase, such as martensite, a soft phase, such as ferrite, and a transitionary phase, such as retained austentite. In this manner, the hard phase provides high strength, the soft phase provides ductility, and the transitionary phase transitions to a hard phase, such as martensite, during a radial expansion and plastic deformation. Furthermore, in this manner, the yield point of the tubular member increases as a result of the radial expansion and plastic deformation. Further, in this manner, the tubular member is ductile, prior to the radial expansion and plastic deformation, thereby facilitating the radial expansion and plastic deformation. In an exemplary embodiment, the composition of a dual-phase expandable tubular member includes (weight percentages): about 0.1% C, 1.2% Mn, and 0.3% Si.
(00297] In an exemplary experimental embodiment, as illustrated in Figs. 36a-36c, one or more of the expandable tubular members, 12, 14, 24, 26, 102, 104, 106, 108, 202, 204 and/or 3502 are processed in accordance with a method 3600, in which, in step 3602, an expandable tubular member 3602a is provided that is a steel alloy having following material composition (by weight percentage): 0.065% C, 1.44% Mn, 0.01% F, 0.002% S, 0.24% Si, 001% Cu, 0.01% Ni, 0.02% Cr, 0.05% V, 0.01 %Mo, 0.01% Nb, and 0.01% Ti.

In an exemplary experimental embodiment, the expandable tubular member 3702a provided in step 3702 has a yield strength of 60 ksi, and a tensile strength of 80 ksi.
[00304] In an exemplary experimental embodiment, as illustrated in Fig. 37b, in step 3702, the expandable tubular member 3702a includes a microstructure that includes pearlite and pearlite striation.
[00305] In an exemplary embodiment, the expandable tubular member 3702a is then heated at a temperature of 790 C for about 10 minutes in step 3704.
[00306) In an exemplary embodiment, the expandable tubular member 3702a is then quenched in water in step 3706.

[00315] In an exemplary embodiment, as illustrated in Fig. 39 and 40, a method 3900 for increasing the collapse strength of a tubular assembly begins with step 3902 in which an expandable tubular member 3902a is provided. The expandable tubular member 3902a includes an inner surface 3902b having an inner diameter D, an outer surface 3902c having an outer diameter D2, and a wall thickness 3902d. In an exemplary embodiment, expandable tubular member 3902a may be, for example, the tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428, 2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068, 3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, or 3500. In an exemplary embodiment, the expandable tubular member 3902a may be, for example, the tubular assembly 10, 22, 100, or 200.
[00316] Referring now to Figs. 39, 41a, 41b, 41c and 41d, the method 3900 continues at step 3904 in which the expandable tubular member 3902a is coated with a layer 3904a of material. In an exemplary embodiment, the layer 3904a of material includes a plastic such as, for example, a PVC plastic 3904aa as illustrated in Fig. 41c, and/or a soft metal such as, for example, aluminum 3904ab as illustrated in Fig. 41d, an aluminum/zinc combination, or equivalent metals known in the art, and/or a composite material such as, for example, a carbon fiber material, and substantially covers the outer surface 3902c of expandable tubular member 3902a. In an exemplary embodiment, the layer 3904a of material is applied using conventional methods such as, for example, spray coating, vapor deposition, adhering layers of material to the surface, or a variety of other methods known in the art.
(00317] Referring now to Figs. 39, 40 and 42, the method 3900 continues at step 3906 in which the expandable tubular member 3902a is positioned within a passage 3906a defined by a preexisting structure 3906b which includes an inner surface 3906c, an outer surface 3906d, and a wall thickness 3906e. In an exemplary embodiment, the preexisting structure 3906b may be, for example, the wellbores 16, 110, or 206. In an exemplary embodiment, the preexisting structure 3906b may be, for example, the tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428, 2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068, 3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, or 3500. In an exemplary embodiment, preexisting structure 3906b may be, for example, the tubular assembly 10, 22, 100, or 200. In an exemplary embodiment, the cross sections of expandable tubular member 3902a and preexisting structure 3906b are substantially concentric when the expandable tubular member 3902a is positioned in the passage 3906a defined by preexisting structure 3906b.
(00318] Referring now to Figs. 39, 43, and 44, the method continues at step 3908 in which the expandable tubular member 3902a is radially expanded and plastically deformed.
In an exemplary embodiment, a force F is applied radially towards the inner surface 3902b of expandable tubular member 3902a, the force F being sufficient to radially expand and plastically deform the expandable tubular member 3902a and the accompanying layer 3904a on its outer surface 3902c. The force F increases the inner diameter D1 and the outer diameter D2 of expandable tubular member 3902a until the layer 3904a engages the inner surface 3906c of preexisting structure 3906b and forms an interstitial layer between the expandable tubular member 3902a and the preexisting structure 3906b. In several exemplary embodiments, the expandable tubular member 3902a is radially expanded and plastically deformed using one or more conventional commercially available devices and/or using one or more of the methods disclosed in the present application.
[00319] In an exemplary embodiment, following step 3908 of method 3900, the layer 3904a forms an interstitial layer filling some or all of the annulus between the expandable tubular member 3902a and the preexisting structure 3906b. In an exemplary embodiment, the interstitial layer formed from the layer 3904a between the expandable tubular member 3902a and the preexisting structure 3906b results in the combination of expandable tubular member 3902a, the layer 3904a, and the preexisting structure 3906b exhibiting a higher collapse strength than would be exhibited without the interstitial layer. In an exemplary embodiment, the radial expansion and plastic deformation of expandable tubular member 3902a with layer 3904a into engagement with preexisting structure 3906b results in a modification of the residual stresses in one or both of the expandable tubular member 3902a and the preexisting structure 3906b. In an exemplary embodiment, the radial expansion and plastic deformation of expandable tubular member 3902a with layer 3904a into engagement with preexisting structure 3906b places at least a portion of the wall thickness of preexisting structure 3906b in circumferential tension.
[00320] In an alternative embodiment, as illustrated in Fig. 45 and 46, a method 4000 for increasing the collapse strength of a tubular assembly begins with step 4002 in which a preexisting structure 4002a is provided. The preexisting structure 4002a defines a substantially cylindrical passage 4002b and includes an inner surface 4002c. In an exemplary embodiment, the preexisting structure 4002a may be, for example, the wellbores 16, 110, or 206. In an exemplary embodiment, the preexisting structure 4002a may be, for example, the tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428, 2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068, 3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, or 3500. In an exemplary embodiment, the preexisting structure 4002a may be, for example, the tubular assembly 10, 22, 100, or 200.
[00321) Referring now to Figs. 45, 47a and 47b, the method 4000 continues at step 4004 in which the inner surface 4002c in passage 4002b of preexisting structure 4002a is coated with a layer 4004a of material. In an exemplary embodiment, the layer 3904a of material includes a plastic, and/or a soft metal such as, for example, aluminum, aluminum and zinc, or equivalent metals known in the art, and/or a composite material such as, for example, carbon fiber, and substantially covers the inner surface 4002c of preexisting structure 4002a. In an exemplary embodiment, the layer 3904a of material is applied using conventional methods such as, for example, spray coating, vapor deposition, adhering layers of material to the surface, or a variety of other methods known in the art.
[00322] Referring now to Figs. 40, 45 and 48, the method 4000 continues at step 4006 in which expandable tubular member 3902a including inner surface 3902b, outer surface 3902c, and wall thickness 3902d, is positioned within passage 4002b defined by preexisting structure 4002a. In an exemplary embodiment, the cross sections of expandable tubular member 3902a and preexisting structure 4002a are substantially concentric when the expandable tubular member 3902a is positioned in the passage 4002b defined by preexisting structure 4002a.
[00323] Referring now to Figs. 45, 49, and 50, the method 4000 continues at step 4008 in which the expandable tubular member 3902a is radially expanded and plastically deformed. In an exemplary embodiment, a force F is applied radially towards the inner surface 3902b of expandable tubular member 3902a, the force F being sufficient to radially expand and plastically deform the expandable tubular member 3902a. The force F increases the inner diameter D1 and the outer diameter D2 of expandable tubular member 3902a until the outer surface 3902c of expandable tubular member 3902a engages layer 4004a on preexisting structure 4002a and forms an interstitial layer between the expandable tubular member 3902a and the preexisting structure 4002a. In several exemplary embodiments, the expandable tubular member 3902a is radially expanded and plastically deformed using one or more conventional commercially available devices and/or using one or more of the methods disclosed in the present application.
[00324] In an exemplary embodiment, following step 4008 of method 4000, the layer 4004a forms an interstitial layer filling some or all of the annulus between the expandable tubular member 3902a and the preexisting structure 4002a. In an exemplary embodiment, the interstitial layer formed from the layer 4004a between the expandable tubular member 3902a and the preexisting structure 4002a results in the combination of the expandable tubular member 3902a, the layer 3904a, and the preexisting structure 4002a exhibiting a higher collapse strength than would be exhibited without the interstitial layer. In an exemplary embodiment, the radial expansion and plastic deformation of expandable tubular member 3902a into engagement with preexisting structure 4002a with layer 4004a results in a modification of the residual stresses in one or both of the expandable tubular member 3902a and the preexisting structure 4002a. In an exemplary embodiment, the radial expansion and plastic deformation of expandable tubular member 3902a with layer 4004a into engagement with preexisting structure 4002a places at least a portion of the wall thickness of the preexisting structure 4002a in circumferential tension.
[00325] In an alternative embodiment, as illustrated in Fig. 51a, step 3904 of method 3900 may include coating multiple layers of material such as, for example, layers 3904a and 4100, on tubular member 3902a, illustrated in Fig. 40. In an exemplary embodiment, the layers 3904a and/or 4100 may be applied using conventional methods such as, for example, spray coating, vapor deposition, adhering layers of material to the surface, or a variety of other methods known in the art.
[003261 In an alternative embodiment, as illustrated in Fig. 51b, step 4004 of method 4000 may include coating multiple layers of material such as, for example, layers 4002c and 4200, on tubular member 4002a. In an exemplary embodiment, the layers 4002c and 4200 may be applied using conventional methods such as, for example, spray coating, vapor deposition, adhering layers of material to the surface, or a variety of other methods known in the art.
(00327] In an exemplary embodiment, steps 3904 of method 3900 and step 4004 of method 4000 may include coating the expandable tubular member 3902a with a layer 3904a of varying thickness. In an exemplary embodiment, step 3904 of method 3900 may include coating the expandable tubular member 3902a with a non uniform layer 3904a which, for example, may include exposing portions of the outer surface 3902c of expandable tubular member 3902a. In an exemplary embodiment, step 4004 of method 4000 may include coating the preexisting structure 4002a with a non uniform layer 4004a which, for example, may include exposing portions of the inner surface 4002c of preexisting structure 4002a.
[00328] In an alternative embodiment, as illustrated in Fig. 52a, 52b, and 52c, step 3904 of method 3900 may be accomplished by laying a material 4300 around an expandable tubular member 4302, which may be the expandable tubular member 3902a in Fig. 40. In an alternative embodiment, step 4004 of method 4000 may be accomplished by using the material 4300 to line the inner surface of the preexisting structure such as, for example, the inner surface 4002c of preexisting structure 4002a. In an exemplary embodiment, the material 4300 may be a plastic, and/or a metal such as, for example, aluminum, aluminum/zinc, or other equivalent metals known in the art, and/or a composite material such as, for example, carbon fiber. In an exemplary embodiment, the material 4300 may include a wire that is wound around the expandable tubular member 4302 or lined on the inner surface 4002c of preexisting structure 4002a. In an exemplary embodiment, the material 4300 may include a plurality of rings place around the expandable tubular member 4302 or lined on the inner surface 4002c of preexisting structure 4002a. In an exemplary embodiment, the material 4300 may be a plurality of discrete components placed on the expandable tubular member 4302 or lined on the inner surface 4002c or preexisting structure 4002a.
[003291 In an exemplary experimental embodiment EXP1 of method 3900, as illustrated in Fig. 53, a plurality of tubular members 3902a were provided, as per step 3902 of method 3900, which had a 7 5/8 inch diameter. Each tubular member 3902a was coated, as per step 3904 of method 3900, with a layer 3904a. The tubular member 3902a was then radially expanded and plastically deformed and the energy necessary to radially expand and plastically deform it such as, for example, the operating pressure required to radially expand and plastically deform the tubular member 3902a, was recorded. In EXP1A, the layer 3904a was aluminum, requiring a maximum operating pressure of approximately 3900 psi to radially expand and plastically deform the tubular member 3902a. In EXP1B, the layer 3904a was aluminum/zinc, requiring a maximum operating pressure of approximately 3700 psi to radially expand and plastically deform the tubular member 3902a. In EXP1, the layer 3904a was PVC plastic, requiring a maximum operating pressure of approximately 3600 psi to radially expand and plastically deform the tubular member 3902a. In EXP1D, the layer 3904a was omitted resulting in an air gap, and requiring a maximum operating pressure of approximately 3400 psi to radially expand and plastically deform the tubular member 3902a.
[00330] In an exemplary experimental embodiment EXP2 of method 3900, as illustrated in Fig. 54a, 54b, and 54c, a plurality of expandable tubular members 3902a were provided, as per step 3902 of method 3900. Each tubular member 3902a was coated, as per step 3904 of method 3900, with a layer 3904a. Each tubular member 3902a was then positioned within a preexisting structure 3906b as per step 3906 of method 3900. Each tubular member 3902a was then radially expanded and plastically deformed 13.3% and the thickness of layer 3904a between the tubular member 3902a and the preexisting structure 3906b was measured. In EXP, the layer 3904a was aluminum and had a thickness between approximately 0.05 inches and 0.15 inches. In EXP26, the layer 3904a was aluminum/zinc and had a thickness between approximately 0.07 inches and 0.13 inches. In EXP2c, the layer 3904a was PVC plastic and had a thickness between approximately 0.06 inches and 0.14 inches. In EXP2D, the layer 3904a was omitted which resulted in an air gap between the tubular member 3902a and the preexisting structure 3906b between approximately 0.02 and 0.04 inches.
[00331] In an exemplary experimental embodiment EXP3 of method 3900, illustrated in Fig. 55a and 55b, a plurality of expandable tubular members 3902a were provided, as per step 3902 of method 3900. Each tubular member 3902a was coated, as per step 3904 of method 3900, with a layer 3904a. Each tubular member 3902a was then positioned within a preexisting structure 3906b as per step 3906 of method 3900. Each tubular member 3902a was then radially expanded and plastically deformed in a preexisting structure 3906b and the thickness of layer 3904a between the tubular member 3902a and the preexisting structure 3906b was measured. In EXP3A, the layer 3904a was plastic with a thickness between approximately 1.6 mm and 2.5 mm. In EXP3B, the layer 3904a was aluminum with a thickness between approximately 2.6 mm and 3.1 mm. In EXP3, the layer 3904a was aluminum/zinc with a thickness between approximately 1.9 mm and 2.5 mm. In EXP3D, the layer 3904a was omitted, resulting in an air gap between the tubular member 3902a and the preexisting structure 3906b between approximately 1.1 mm and 1.7 mm. Fig. 55b illustrates the distribution of the gap thickness between the tubular member and the preexisting structure for EXP3A, EXP39, EXP3, and EXP3D, illustrating that combinations with an layer between the tubular member 3902a and the preexisting structure 3906b exhibit a more uniform gap distribution.
[00332] In an exemplary experimental embodiment EXP4 of method 3900, a plurality of expandable tubular members 3902a were provided, as per step 3902 of method 3900.
Each tubular member 3902a was coated, as per step 3904 of method 3900, with a layer 3904a. Each tubular member 3902a was then positioned within a preexisting structure 3906b as per step 3906 of method 3900. Each tubular member 3902a was then radially expanded and plastically deformed in a preexisting structure 3906b, and conventional collapse testing was performed on the tubular assembly comprised of the tubular member 3902a, layer 3904a and preexisting structure 3906b combination. For the testing, the preexisting structure 3906b was composed of a P-lb Grade pipe with an inner diameter of approximately 9 5/8 inches. The expandable tubular member 3902a was composed of an LSX-80 Grade pipe with an inner diameter of approximately 7 5/8 inches. The tubular member assemblies exhibited the following collapse strengths: Collapse Layer Remarks EXP4 Strength 3904a (psi) EXP4A plastic 14230 This was an unexpected result.
EXP43 aluminum/zinc 20500 This was an unexpected result.
EXP4 air 14190 This was an unexpected result.
EXP40 aluminum 20730 This was an unexpected result.
EXP4A, EXP4B, EXP4, and EXP4D illustrate that using a soft metal such as, for example aluminum and or aluminum/zinc, as layer 3904a in method 3900 increases the collapse strength of the tubular assembly comprising the expandable tubular member 3902a, layer 3904a, and preexisting structure 3906b by approximately 50% when compared to using a layer 3904a of plastic or omitting the layer 3904a. This was an unexpected result.
[00333] In an exemplary experimental embodiment EXP5 of method 3900, as illustrated in Fig. 56 and 56a, an expandable tubular member 3902a was provided, as per step 3902 of method 3900. The coating of step 3904 with a layer 3904a was omitted. The tubular member 3902a was then positioned within a preexisting structure 3906b as per step 3906 of method 3900. The tubular member 3902a was then radially expanded and plastically deformed in a preexisting structure 3906b, resulting in an air gap between the tubular member 3902a and the preexisting structure.
[00334] In an exemplary embodiment, the collapse resistance of a tubular assembly that includes a pair of overlapping tubular members coupled to each other may be determined using the following equation: = K(PCO + P) P0 is the collapse resistance of an outer casing such as, for example, the preexisting structure 3906b or 4002a, or the wellbores 16, 110, or 206. P is the collapse resistance of an inner casing such as, for example, the tubular member 12, 14, 24, 26, 102, 108, 202, 204, 2210, 2228, 2310, 2328, 2410, 2428, 2510, 2528, 2610, 2628, 2710, 2728, 2910, 2926, 3010, 3024, 3030, 3044, 3050, 3068, 3110, 3124, 3210, 3220, 3310, 3330, 3410, 3432, 3500, or 3902a, or the tubular assembly 10, 22, 100, or 200. K is a reinforcement factor provided by a coating such as, for example, the coating 3904a or 4004a. In an exemplary embodiment, the reinforcement factor K increases as the strength of the material used for the coating increases.
[00335] In an exemplary experimental embodiment EXP6 of method 3900, as illustrated in Figs. 58a, 58b, a computer simulation was run for an expandable tubular member 3902a provided, as per step 3902 of method 3900, positioned within a preexisting structure 3906b, as per step 3906 of method 3900, and radially expanded and plastically deformed in the preexisting structure 3906b. The coating of step 3904 with a layer 3904a was omitted. The radial expansion and plastic deformation of expandable tubular member 3902a resulted in an air gap distribution between the expanded tubular member 3902a and the preexisting structure 3906b, illustrated in Fig. 58b. The tubular member 3902a was a LSX-80 Grade pipe with a 7 5/8 inch inner diameter and the preexisting structure 3906b was a P110 Grade pipe with a 9 5/8 inch inner diameter. The tubular member 3902a was radially expanded and plastically deformed 13.3% from its original diameter. After expansion, the maximum air gap was approximately 2 mm. The expandable tubular member 3902a and preexisting structure 3906b combination exhibited a collapse strength of approximately 13200 psi. This was an unexpected result.

The coating of step 3904 with a layer 3904a was omitted.
The radial expansion and plastic deformation of expandable tubular member 3902a resulted in an air gap distribution between the expanded tubular member 3902a and the preexisting structure 3906b, illustrated. The tubular member 3902a was a LSX-80 Grade pipe with a 7 5/8 inch inner diameter and the preexisting structure 3906b was a P110 Grade pipe with a 9 5/8 inch inner diameter. The tubular member 3902a was radially expanded and plastically deformed 149% from its original diameter. After expansion, the maximum air gap was approximately 1.55 mm. The expandable tubular member 3902a and preexisting structure 3906b combination exhibited a collapse strength of approximately 13050 psi. This was an unexpected result.
[00337] In an exemplary experimental embodiment EXP8 of method 3900, as illustrated in Figs. 59, a computer simulation was run for an expandable tubular member 3902a provided, as per step 3902 of method 3900, coated with a layer 3904a of soft metal, as per step 3904 of method 3900, positioned within a preexisting structure 3906b as per step 3906 of method 3900, and radially expanded and plastically deformed in a preexisting structure 3906b. The tubular member 3902a was a LSX-80 Grade pipe with a 7 5/8 inch inner diameter and the preexisting structure 3906b was a P110 Grade pipe with a 9 5/8 inch inner diameter. In an exemplary embodiment, the soft metal distribution between the tubular member 3902a and the preexisting structure 3906b included aluminum. In an exemplary embodiment, the soft metal distribution between the tubular member 3902a and the preexisting structure 3906b included aluminum and zinc. The tubular member 3906 was radially expanded and plastically deformed 13.3% from its original diameter.
