Definitions
- This inventionrelates generally to oil and gas exploration, and in particular to forming and repairing wellbore casings to facilitate oil and gas exploration.
- a relatively large borehole diameteris required at the upper part of the wellbore.
- Such a large borehole diameterinvolves increased costs due to heavy casing handling equipment, large drill bits and increased volumes of drilling fluid and drill cuttings.
- increased drilling rig timeis 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.
- a wellboretypically traverses a number of zones within a subterranean formation.

- This invention relates generally to oil and gas exploration, and in particular to forming and repairing wellbore casings to facilitate oil and gas exploration.
- 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.
- 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.
- The present invention is directed to overcoming one or more of the limitations of the existing procedures for forming and/or repairing wellbore casings.
- 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 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.
- 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 assembly within the borehole.
- According to another aspect of the present invention, an 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.
- 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.
- 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 with the ends of the first and second tubular members.
- 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.
- 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.
