Abstract: A wellhead is formed by extruding a plurality of tubular liners off of a mandrel into contact with an outer casing. The first tubular liner and mandrel are positioned within the wellbore with the tubular liner in an overlapping relationship with the outer casing. At least a portion of the tubular liner is extruded off of the mandrel into contact with the interior surface of the outer casing. The first tubular liner is extruded off of the mandrel by pressurizing an interior portion of the first tubular liner. Subsequent tubular liners are positioned in concentric overlapping relation and similarly extruded off of a mandrel into at least partial contact with the interior surface of the outer casing.

Abstract: First and second members, representatively first and second portions of a collet assembly, are removably coupled to one another by aligning slots in the first member with slots in the second members to form opposing slot pairs into which coupling members are inserted in first directions. The inserted coupling members are removed from the slot pairs, in second directions opposite from the first directions, in response to the generation of a fluid pressure.

Abstract: A wellbore casing formed by extruding a tubular liner off of a mandrel. The tubular liner and mandrel are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with an existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the mandrel and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the mandrel. The tubular liner is then extruded off of the mandrel.

Abstract: An apparatus for radially expanding and plastically deforming a tubular member including a support member comprising a fluid passage, an expansion device for radially expanding and plastically deforming the tubular member movably coupled to the support member for longitudinal displacement relative to the support member, at least one pressure chamber defined by and positioned between the support member and expansion device fluidicly coupled to the first fluid passage, and releasable supports coupled to the support member adapted to support the tubular member, wherein the releasable supports are positioned above and below the expansion device.

Abstract: An expansion mandrel includes a lubrication system for lubricating the trailing edge portion of the interface between the expansion mandrel and a tubular member during the radial expansion of the tubular member.

Abstract: A method of creating a casing in a borehole located in a subterranean formation including: supporting a tubular liner and an expansion device in the borehole using a support member; injecting fluidic material into the borehole; pressurizing an interior region of the expansion device; displacing a portion of the expansion device relative to the support member and the tubular liner in the longitudinal direction; and radially expanding the tubular liner.

Abstract: A wellbore casing is formed simultaneously with the drilling out of the wellbore.

Abstract: An apparatus for radially expanding tubular members.

Abstract: A method for expanding tubulars including providing an expandable tubing and a larger diameter tubing, wherein the larger diameter tubing has an expandable, tapering end portion; coupling an end portion of the expandable tubing to the expandable tapering end portion of the larger diameter tubing; running the connected tubing into a bore; and expanding the expandable tubing. Prior to the expanding of the expandable tubing, a wall thickness of the end portion of the expandable tubing coupled to the expandable tapering end portion of the larger diameter tubing is less than a wall thickness of another end portion of the expandable tubing.

Abstract: A structural support.

Abstract: An expandable threaded connection includes a first tubular member, a second tubular member and a threaded connection for coupling the tubular members that includes one or more sealing members.

Abstract: A tubular member is expanded by pressurizing an interior region within the tubular member.
