Patent number: 7159665Abstract: 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.Type: GrantFiled: July 19, 2002Date of Patent: January 9, 2007Assignee: Shell Oil CompanyInventors: Robert Lance Cook, David Paul Brisco, R. Bruce Stewart, Lev Ring, Richard Carl Haut, Robert Donald Mack

Patent number: 7147053Abstract: 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.Type: GrantFiled: August 13, 2004Date of Patent: December 12, 2006Assignee: Shell Oil CompanyInventors: Robert Lance Cook, David Paul Brisco, R. Bruce Stewart, Lev Ring, Richard Carl Haut, Robert Donald Mack

Patent number: 7048067Abstract: An apparatus and method for repairing a wellbore casing (100). An opening (115) in a wellbore casing (100) is located using a logging tool (310). An expandable tubular member (370) is then positioned in opposition to the opening (115) in the wellbore casing (100). The expandable tubular member (370) is then radially expanded into intimate contact with the wellbore casing (100).Type: GrantFiled: October 31, 2000Date of Patent: May 23, 2006Assignee: Shell Oil CompanyInventors: Robert Lance Cook, David P. Brisco, R. Bruce Stewart, Reece E. Wyant, Lev Ring, James Jang Woo Nahm, Richard Haut, Robert D. Mack, Alan B. Duell, Andrei Gregory Filippov, Kenneth Michael Cowan, William Joseph Dean

Patent number: 7021390Abstract: 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.Type: GrantFiled: April 18, 2003Date of Patent: April 4, 2006Assignee: Shell Oil CompanyInventors: Robert Lance Cook, David Paul Brisco, R. Bruce Stewart, Lev Ring, Richard Carl Haut, Robert Donald Mack
