BACKGROUND OF THE INVENTION
[0004] This invention relates generally to oil and gas exploration,
and in particular to forming and repairing wellbore casings to
facilitate oil and gas exploration.
[0005] Conventionally, when a wellbore is created, a number of
casings are installed in the borehole to prevent collapse of the
borehole wall and to prevent undesired outflow of drilling fluid
into the formation or inflow of fluid from the formation into the
borehole. The borehole is drilled in intervals whereby a casing
which is to be installed in a lower borehole interval is lowered
through a previously installed casing of an upper borehole
interval. As a consequence of this procedure the casing of the
lower interval is of smaller diameter than the casing of the upper
interval. Thus, the casings are in a nested arrangement with casing
diameters decreasing in downward direction. Cement annuli are
provided between the outer surfaces of the casings and the borehole
wall to seal the casings from the borehole wall. As a consequence
of this nested arrangement a relatively large borehole diameter is
required at the upper part of the wellbore. Such a large borehole
diameter involves increased costs due to heavy casing handling
equipment, large drill bits and increased volumes of drilling fluid
and drill cuttings. Moreover, increased drilling rig time is
involved due to required cement pumping, cement hardening, required
equipment changes due to large variations in hole diameters drilled
in the course of the well, and the large volume of cuttings drilled
and removed.
[0006] During oil exploration, a wellbore typically traverses a
number of zones within a subterranean formation. Wellbore casings
are then formed in the wellbore by radially expanding and
plastically deforming tubular members that are coupled to one
another by threaded connections existing methods for radially
expanding and plastically deforming tubular members coupled to one
another by threaded connections are not always reliable and do not
always produce satisfactory results. In particular, the threaded
connections can be damaged during the radial expansion process.
Furthermore, the threaded connections between adjacent tubular
members, whether radially expanded or not, are typically not
sufficiently coupled to permit the transmission of energy through
the tubular members from the surface to the downhole location.
Further, the damaged threads may permit undesirable leakage between
the inside of the casing and the exterior of the casing.
[0007] The present invention is directed to overcoming one or more
of the limitations of the existing procedures for forming and/or
repairing wellbore casings.
SUMMARY OF THE INVENTION
[0008] According to one aspect of the present invention, an
assembly is provided that includes a first tubular member
comprising a pin member including external threads, an external
sleeve including: a first box member at one end including internal
threads coupled to the external threads of the pin member of the
first tubular member, and a second box member at another end

pin member including external threads coupled to the internal
threads of the second box member of the external sleeve, and an
internal sleeve that receives the ends of the pin members of the
first and second tubular members comprising an external flange that
engages the ends of the pin members of the first and second tubular
members and the external sleeve.
[0009] According to another aspect of the present invention, a
method for forming a wellbore casing is provided that includes
positioning any one, portion, or combination, of the exemplary
embodiments described and illustrated within the present
application within a borehole that traverses a subterranean
formation, and radially expanding and plastically deforming the

apparatus is provided that includes a wellbore that traverses a
subterranean formation, and a wellbore casing positioned within and
coupled to the wellbore. The wellbore casing is coupled to the
wellbore by a process including: positioning any one, portion, or
combination, of the exemplary embodiments described and illustrated
within the present application within the wellbore, and radially
expanding and plastically deforming the assembly within the
wellbore.
[0011] According to another aspect of the present invention, a
system for forming a wellbore casing is provided that includes
means for positioning any one, portion, or combination, of the
exemplary embodiments described and illustrated within the present
application within a borehole that traverses a subterranean
formation, and means for radially expanding and plastically
deforming the assembly within the borehole.
[0012] According to another aspect of the present invention, an
assembly is provided that includes a first tubular member
comprising a pin member including external threads, a second
tubular member comprising a box member including internal threads
coupled to the external threads of the pin member of the first
tubular sleeve, and an external sleeve coupled to and overlapping

[0013] According to another aspect of the present invention, a
method for providing a fluid tight seal between a first tubular
member that is threadably coupled to a second tubular member is
provided that includes providing a stress concentrator one at least
one of the first and second tubular members, and radially expanding
and plastically deforming the first and second tubular members.
[0014] According to another aspect of the present invention, a
method for providing a fluid tight seal between a first tubular
member comprising external threads and a second tubular member
comprising internal threads, wherein the external threads of the
first tubular member engage the internal threads of the second
tubular member, is provided that includes spacing apart the
external and internal threads of the first and second tubular
members into a plurality of groups, and radially expanding and
plastically deforming the first and second tubular members.

disclosures of which are incorporated herein by reference.
[0023] In an exemplary embodiment, the radial expansion and plastic
deformation of the first tubular member 210, the second tubular
member 220, and the external sleeve 222 causes the interfaces
between one or more of the first tubular member, the second tubular
member, and/or the external sleeve to be fluid tight. In an
exemplary embodiment, during the radial expansion and plastic
deformation of the first tubular member 210, second tubular member
220, and the external sleeve 222, the annular recess 224 of the pin
member 212 of the first tubular member 210 provides a stress
concentration that enhances the sealing of the interface between
the end of the pin member of the first tubular member and the box
member 218 of the second tubular member 220. In an exemplary
embodiment, during the radial expansion and plastic deformation of
the first tubular member 210, second tubular member 220, and the
external sleeve 222, the spaced apart external and internal
threads, 214a-214c, and 216a-216c, of the first and second tubular
members, 210 and 220, facilitate the formation of a fluid tight
seal of the interface between the end of the pin member of the
first tubular member and the box member 218 of the second tubular
member 220.
[0024] In an alternative embodiment of the illustrative embodiment
of FIG. 3, the orientation of one or more of the various elements
may be reversed. For example, the external sleeve 222 may be an
internal sleeve, the pin member 212 of the first tubular member 210
may be a box member, and the box member 218 of the second tubular
member 220 may be a pin member.
[0025] An assembly has been described that includes a first tubular
member comprising a pin member including external threads, an
external sleeve including: a first box member at one end including
internal threads coupled to the external threads of the pin member
of the first tubular member, and a second box member at another end
including internal threads, a second tubular member comprising a
pin member including external threads coupled to the internal
threads of the second box member of the external sleeve, and an
internal sleeve that receives the ends of the pin members of the
first and second tubular members comprising an external flange that
engages the ends of the pin members of the first and second tubular
members and the external sleeve. In an exemplary embodiment, the
external flange of the internal sleeve defines an upper annular
recess for receiving and mating with the first tubular member, and
the external flange of the internal sleeve further defines a lower
annular recess for receiving and mating with the second tubular
member.
[0026] A method for forming a wellbore casing has been described
that includes positioning any one, portion, or combination, of the
exemplary embodiments described and illustrated within the present
application within a borehole that traverses a subterranean
formation, and radially expanding and plastically deforming the
assembly within the borehole.
[0027] An apparatus has been described that includes a wellbore
that traverses a subterranean formation, and a wellbore casing
positioned within and coupled to the wellbore. The wellbore casing
is coupled to the wellbore by a process including: positioning any
one, portion, or combination, of the exemplary embodiments
described and illustrated within the present application within the
wellbore, and radially expanding and plastically deforming the
assembly within the wellbore.
[0028] A system for forming a wellbore casing has been described
that includes means for positioning any one, portion, or
combination, of the exemplary embodiments described and illustrated
within the present application within a borehole that traverses a
subterranean formation, and means for radially expanding and
plastically deforming the assembly within the borehole.
[0029] An assembly has been described that includes a first tubular
member comprising a pin member including external threads, a second
tubular member comprising a box member including internal threads
coupled to the external threads of the pin member of the first
tubular sleeve, and an external sleeve coupled to and overlapping
with the ends of the first and second tubular members. In an
exemplary embodiment, the external threads of the pin member of the
first tubular member comprise a plurality of spaced apart groups of
external threads, and the internal threads of the box member of the
second tubular member comprise a plurality of spaced apart groups
of internal threads. In an exemplary embodiment, the external
surface end of the pin member of the first tubular member includes
a stress concentrator. In an exemplary embodiment, the external
threads of the pin member of the first tubular member include a
plurality of spaced apart groups of external threads, the internal
threads of the box member of the second tubular member include a
plurality of spaced apart groups of internal threads, and the
external surface end of the pin member of the first tubular member
comprises a stress concentrator.
[0030] A method for providing a fluid tight seal between a first
tubular member that is threadably coupled to a second tubular
member has been described that includes providing a stress
concentrator one at least one of the first and second tubular
members, and radially expanding and plastically deforming the first
and second tubular members.
[0031] A method for providing a fluid tight seal between a first
tubular member comprising external threads and a second tubular
member comprising internal threads, wherein the external threads of
the first tubular member engage the internal threads of the second
tubular member, has been described that includes spacing apart the
external and internal threads of the first and second tubular
members into a plurality of groups, and radially expanding and
plastically deforming the first and second tubular members.
