Patent number: 7370707Abstract: Aspects of the present invention provide a tubular handling system for handling wellbore tubulars. In one aspect, the present invention provides a tubular handling system adapted to retain a tubular without damaging the outer surface of the tubular. In another aspect, the present invention provides a method of connecting tubulars by remotely controlling the connection process, including joint compensation, alignment, make up, and interlock. In one embodiment, the tubular handling system comprises an elevator adapted to support a tubular utilizing a first portion of an upset of the tubular and a spider adapted to support the tubular utilizing a second portion of the upset. In another embodiment, at least one of the elevator and the spider is remotely controllable. In yet another embodiment, the tubular handling system comprising a joint compensator system adapted to provide fluid communication to the elevator during rotation of the tubular.Type: GrantFiled: April 5, 2004Date of Patent: May 13, 2008Assignee: Weatherford/Lamb, Inc.Inventors: Gary McDaniel, Allen Keith Thomas, Jr., Patrick D. Cummins, Troy F. Hill, Tracy J. Cummins, Doyle Frederic Boutwell, Jr., Michael Hayes

Patent number: 7367403Abstract: A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider that is normally mounted on the rig floor is supported by a table elevated above the rig floor. Supporting the spider on an elevated table provides personnel with access to a portion of the length of the pipe string below the elevated spider and above the rig floor for applying a fastener to secure the control line to the pipe string. The control line is supplied from above the spider and is positioned by a control line guide supported on the spider or a sleeve to pass through the spider outside the path of the pipe gripping members, such as slips.Type: GrantFiled: January 9, 2006Date of Patent: May 6, 2008Assignee: Frank's Casing Crew & Rental Tools, Inc.Inventors: Charles Michael Webre, Brian Begnaud, Vernon Bouligny

Patent number: 7360589Abstract: An apparatus for performing well intervention work on a rig. The apparatus comprises a first spreader that is operatively connected to a derrick, a pair of I-beams that have a distal end and a proximal end, and wherein the distal end of the pair of I-beams are connected to the first spreader. The apparatus further comprises a second spreader, and wherein the proximal end of the I-beams is connected to the second spreader. The apparatus further comprises a first pivot point on the first spreader and a second pivot point on the second spreader. In the most preferred embodiment, the apparatus further comprises a door, operatively attached to the second spreader, for allowing entry of the tubular. Also, the second spreader may include a shoulder for engagement with a tubular so that the tubular is supported by the second spreader so that the weight of the tubular can be transferred to the second spreader. A method of lifting a tubular used in well intervention work on a rig is also disclosed.Type: GrantFiled: October 27, 2005Date of Patent: April 22, 2008Assignee: Devin International, Inc.Inventors: James Devin Moncus, Joseph Hayden Miller, Jr., Bryan Duhon

Patent number: 7341101Abstract: A relatively light weight wire-line conveyance mechanism capable of sustained high pressure incorporated into a wire-line riser set-up and configured to allow multiple radial bends without sheaves. The conveyance mechanism includes a tubular body structure capable of being pressurized defining a radial arc of between 0 and 180 degree having a threaded coupling at each end for connection to riser tubular joints. One embodiment discloses a field formable cable conveyor that may take a variety of shapes. The tubular body contains a series of connected tubular blocks or sleeves, each of which includes a longitudinal bore and a roller or ball bearing assembly therein defining a wire-line pathway for receiving a wire-line that passes through each of said tubular blocks, fully contained therein.Type: GrantFiled: May 30, 2006Date of Patent: March 11, 2008Inventor: Benny W. Moretz
