Patent number: 7487831Abstract: The present invention provides a downhole cementing apparatus run into a borehole on a tubular. The apparatus is constructed on the pipe in such a way that pressure surge during run-in is reduced by allowing fluid to enter the pipe and utilize the fluid pathway of the cement. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In another aspect of the invention, various methods are provided within the cementing apparatus to loosen and displace sediment in the borehole prior to cementing.Type: GrantFiled: July 16, 2007Date of Patent: February 10, 2009Assignee: Weatherford/Lamb, Inc.Inventors: Clayton Stanley Pluchek, Gerald Dean Pedersen, Richard Lee Giroux, Thad Joseph Scott, David Michael Haugen

Patent number: 6976536Abstract: A method of expanding tubing comprises locating an expansion tool in a section of tubing to be expanded, applying a fluid pressure to the tubing to create a fluid pressure expansion force and induce a hoop stress in the tubing, and applying a mechanical expansion force to the tubing via the expansion tool. The combined fluid pressure expansion force and mechanical expansion force is selected to be sufficient to induce expansion of the tubing.Type: GrantFiled: March 22, 2004Date of Patent: December 20, 2005Assignee: Weatherford/Lamb, Inc.Inventors: Neil Andrew Abercrombie Simpson, David Michael Haugen

Patent number: 6257339Abstract: A wellbore system with a tubular string extending from an earth surface down into a wellbore in the earth, a packer system with a selectively settable packer element, and a disconnect located between an end of the tubular string and the packer system, the disconnect operable from the surface by imposing a downward force on the tubular string. In one aspect the packer system's packer element is a tension-set packer element. A wellbore disconnect with a top sub, a piston having an upper end secured to the top sub and a portion below the upper end releasably secured with at least one releasable member to a carrier member, the carrier member having apparatus for selectively gripping the piston, the apparatus for selectively gripping the piston also selectively gripping a bottom sub within which the piston is movable, the at least one releasable member releasable in response to a downward force on the disconnect.Type: GrantFiled: October 2, 1999Date of Patent: July 10, 2001Assignee: Weatherford/Lamb, IncInventors: David Michael Haugen, Gary Duron Ingram, Corey Eugene Hoffman, Robert Stephen Beeman

Patent number: 6202752Abstract: New wellbore milling systems and methods of their use have been developed, the milling system in one aspect including at least one mill, at least one stabilizing member connected to and above the at least one mill, and the at least one stabilizing member for maintaining position of the at least one mill for milling through the liner into the main wellbore. In certain aspects multiple spaced-apart stabilizers are used above a mill which, in one aspect, may include one or more reaming stabilizers. In one aspect the lowermost stabilizer is spaced-apart from a mill so that the stabilizer does not enter a bend portion of a liner to be milled until milling has commenced.Type: GrantFiled: February 18, 1999Date of Patent: March 20, 2001Assignee: Weatherford/Lamb, Inc.Inventors: Marc David Kuck, Thomas Floyd Bailey, Monte Ira Johnson, Robert Eugene Robertson, Andrew Arthur Barry, Thurman Beamer Carter, William Allen Blizzard, Jr., Teme Forrest Singleton, John Douglas Roberts, William Alan Spielman, David Michael Haugen, Guy LaMonte McClung, III
