摘要: A mono-diameter wellbore casing is formed by radially expanding a first tubular liner off of a mandrel into contact with a second tubular liner. The first and second tubular liners are positioned within the wellbore in an overlapping relationship. The overlapping portions of the tubular liners include thin wall portions with compressible annular members that are expanded into contact with each other.

摘要: A mono-diameter wellbore casing. A tubular liner and an expansion cone are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with a pre-existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the expansion cone 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 expansion cone. The tubular liner is then extruded off of the expansion cone. The overlapping portion of the pre-existing casing and the tubular liner are then radially expanded using an expansion cone.

摘要: 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.

摘要: 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.

摘要: An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.
