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 YP,, and the second
expandable
tubular member 14 has a plastic yield point YP~. 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

expandable tubular
member 12 and/or the second expandable tubular member 14 have a ductility DPE
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 andlor inside diameter.
[00162] Referring to Fig. 8, an exemplary embodiment of an expandable tubular
assembly

100 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
YP,, 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, the plastic
yield point YP,
is less than the plastic yield point YP~. 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.

[00168] 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 DPE
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 YSqE 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 tit 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 foNowing
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
29


CA 02537242 2006-02-27

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 (WTf/WTo)/In (Df/Do);
where AR = anisotropy ratio;
where WTf = final wall thickness of the expandable tubular member following
the
radial expansion and plastic deformation of the expandable tubular member;
where WT; = initial wall thickness of the expandable tubular member prior to
the
radial expansion and plastic deformation of the expandable tubular member;
where Df = 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,
204x, 204b, 204c, and 2044, 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, 7 02, 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 DPE 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


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
DqE, and YSAE is greater than YSpE. 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

12, 14, 24, 26, 102, 104, 106, 108, 202 and/or 204, are characterized by an
expandability
coefficient f:
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

[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+Mnl6+~Cr+Mo+V+Ti+Nb~IS+~Ni+Cu~llS
where Ce - carbon equivalent value;
a. C - carbon percentage by weight;
b. Mn - manganese 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 Ce, for tubular
members
having more than 0.12% carbon content (by weight), is given by the following
expression:
C~ =C+Sil30+~Mh+Cu+Ct-)l20+Nil60+MollS+YllO+5*B

[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,
36


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
for example, a cased or uncased wellbore, 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 radial expansion and plastic deformation of the first and
second
tubular members, 2210 and 2228, the tubular sleeve 2216 is also radially
expanded and
plastically deformed. As a result, 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, Weathertord 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
37

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
fop 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 andlor 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 in circumferential 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 fio 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, fiuidic 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.
[00218] 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

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
plasfiically 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

[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 wellbore, 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 2776 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.

vented from the
tubular members.
[00239] The first and second tubular members 2910 and 2926, and the tubular

[00261] Referring to Fig. 31, in an exemplary embodiment, a first tubular

3110 includes internally threaded connections, 3112a and 3112b, spaced apart
by a non-

[00262] First, second, and/or third tubular sleeves, 3126, 3128, and 3130, are

[00263] The internally threaded connections, 3112a and 3112b, of the end

threaded

are pin connections.
[00264] The first and second tubular members 3110 and 3124, and the tubular

as, for example, a wellbore, and radially expanded and plastically deformed,
for example, by

[00265] During the radial expansion and plastic deformation of the first and

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

[00268] Referring to Fig. 32a, in an exemplary embodiment, a first tubular
member
3210 includes an internally threaded connection 3212 at an end portion 3214.
An externally
threaded connection 3216 of an end portion 3218 of a second tubular member
3220 are
threadably coupled to the internally threaded connection 3212 of the end
portion 3214 of the
first tubular member 3210.
[00269] The internally threaded connection 3212 of the end portion 3214 of the
first
tubular member 3210 is a box connection, and the externally threaded
connection 3216 of
the end portion 3218 of the second tubular member 3220 is a pin connection.
[00270] A tubular sleeve 3222 including internal flanges 3224 and 3226 is
positioned
proximate and surrounding the end portion 3214 of the first tubular member
3210. 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 is also 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


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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 wellbore, 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.
[00279] 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.
[00280] 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
51


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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 fihe 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
52


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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 fihrough 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 inferiors
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
53


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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 andlor 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.
[00292] 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
54


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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. Furthermore, the tubular sleeve 3418 may prevent crack propagation
during the
radial expansion and plastic deformation of the first and second tubular
members, 3410 and
3432. In this .manner, failure modes such as, for example, longitudinal cracks
in the end
portions, 3416 and 3430, 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 fiirst 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.
[00293] 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

[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
56


CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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.
[00295] 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 fihe
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.

108, 202,
204 and/or 3502 are processed in accordance with a method 3700, in which, in
step 3702,
an expandable tubular member 3702a is provided that is a steel alloy having
following
material composition (by weight percentage): 0.18% C, 1.28% Mn, 0.017% P,

[00312] In an exemplary embodiment, the expandable tubular member 3802a is

CA 02537242 2006-02-27
WO 2005/086614 PCT/US2004/028887
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 D~, and a wall thickness 3902d. In an exemplary embodiment,

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 D~ and
the outer

WO 2005/086614 PCT/US2004/028887
diameter Dz 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 wifih 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 D~ and the outer diameter D~ 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.

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

[00328] In an alternative embodiment, as illustrated in Fig. 52x, 52b, and

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.

an alternative embodiment, step 4004 of method 4000 may be accomplished by
using the
material 4300 to line the inner surtace of the preexisting structure such as,
for example, the
inner surface 4002c of preexisting structure 4002x. 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
fined on the
inner surface 4002c of preexisting structure 4002x. In an exemplary

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 EXP~A, fihe
layer 3904a
was aluminum, requiring a maximum operating pressure of approximately 3900 psi
to

EXP~~, 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. fn EXP,p,
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

[00330] In an exemplary experimental embodiment EXP~ of method 3900, as
illustrated in Fig. 54a, 54b, and 54c, a plurality of expandable tubular

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 EXP~B, the layer 3904a
was
aluminum/zinc and had a thickness between approximately 0.07 inches and 0.13
inches. In
EXP2~, the layer 3904a was PVC plastic and had a thickness between
approximately 0.06
inches and 0.14 inches. In EXP2p, 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.
[0033'!] 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

was then radially expanded and plastically deformed in a preexisting structure
3906b and the

was
aluminum/zinc with a thickness between approximately 1.9 mm and 2.5 mm. In
EXP3p, 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, EXP3B, EXP3~, and EXP3~, illustrating that combinations
with an layer

more
uniform gap distribution.
[00332] In an exemplary experimental embodiment EXP4 of method 3900, a
plurality

3900.
Each tubular member 3902a was coated, as per step 3904 of method 3900, with a
layer
3904x. Each tubular member 3902a was then positioned within a preexisting

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
3902x, layer 3904a and preexisting structure 3906b combination. For the
testing, the
preexisting structure 3906b was composed of a P-110 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

strength of the tubular assembly comprising the expandable tubular member
3902x, layer

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

material used for
the coating increases.
