Patent number: 8181707Abstract: The present invention generally relates to a method and apparatus for protecting tubular connections. In one aspect, an expandable tubular connection for use in a wellbore is provided. The tubular connection includes a tubular pin member. The tubular connection also includes a tubular box member having an end portion, wherein the tubular pin member is matable with the tubular box member to form the tubular connection. Additionally, the tubular connection includes a sleeve member disposed on the tubular pin member, wherein the sleeve member is configured to substantially protect the end portion of the tubular box member as the tubular connection is lowered into the wellbore. In yet a further aspect, a method for utilizing a tubular connection in a wellbore is provided.Type: GrantFiled: September 20, 2010Date of Patent: May 22, 2012Assignee: Weatherford/Lamb, Inc.Inventors: Merle E. Evans, John Richard Setterberg, Jr., Lev Ring, Ghazi J. Hashem, Richard W. DeLange

Patent number: 8167050Abstract: An internally gripping tong to rotate tubular segments comprising a central cam body rotatably disposed within a housing having a plurality of windows. The cam body is surrounded by a plurality of angularly distributed gripping jaws slidably received within the windows. The tong is disposed within a bore of a tubular segment, and rotation of the housing relative to the cam body deploys the gripping jaws radially outwardly within the windows to engage the interior wall of the tubular segment. The tong may be self-energizing in both the make-up and the break-out modes of operation. The tong may be deployed to grip the tubular segment using a device to frictionally couple the housing to the tubular segment that cooperates with the top drive assembly, or by an internal actuator that imparts rotation to the housing relative to the cam body.Type: GrantFiled: July 1, 2009Date of Patent: May 1, 2012Assignee: Frank's casing Crew & Rental Tools, Inc.Inventors: Charles Michael Webre, Brennan Scott Domec, Vernon J. Bouligny

Patent number: 8167038Abstract: The present invention generally provides methods and apparatus for connecting threaded members while ensuring that a proper connection is made, particularly for premium grade connections. In one embodiment, a method of connecting threaded tubular members for use in a wellbore or a riser system is provided. The method includes the acts of operating a power drive unit, thereby rotating a first threaded tubular member relative to a second threaded tubular member; measuring the rotation of the first threaded tubular member; and compensating the rotation measurement by subtracting a deflection of at least one of: the power drive unit, and one of the tubular members.Type: GrantFiled: August 3, 2009Date of Patent: May 1, 2012Assignee: Weatherford/Lamb, Inc.Inventors: Doyle Boutwell, John Newman, Graham Ruark, Aaron Dauphine

Publication number: 20120097402Abstract: A tubular member handling apparatus including a tubular member running tool, an elevator, first actuators each extending between the running tool and the elevator, and second actuators each extending between the running tool and a corresponding first actuator. The running tool includes a slotted member having a plurality of elongated slots, a recessed member slidably coupled to the slotted member and having a plurality of recesses, and a plurality of rolling members each retained between one of the recesses and one of the slots. Each rolling member partially extends through an adjacent slot when located in a shallow end of a corresponding recess, and retracts to within an outer perimeter of the slotted member when located in a deep end of the corresponding recess.Type: ApplicationFiled: November 10, 2011Publication date: April 26, 2012Applicant: Canrig Drilling Technology Ltd.Inventors: Brian Ellis, Craig Weems
