Patent number: 7150330Abstract: A hydraulic circuit and method for operating a gripping mechanism according to which fluid is passed from a source to the device while some of the fluid is passed to a valve that is adjustable to control the amount of fluid passed to it and therefore the amount of fluid passed to the device.Type: GrantFiled: May 6, 2004Date of Patent: December 19, 2006Assignee: Halliburton Energy Services, Inc.Inventor: Robert E. Domann

Patent number: 7090026Abstract: An apparatus and method for moving a tubing along a path, according to which the tubing is engaged by an outer chain which is driven to advance the tubing. The chain is adapted to be deflected radially in response to an increase in the diameter of the tubing, and a plate is compressed in response to the deflection of the chain to accommodate the variation in diameter.Type: GrantFiled: May 6, 2004Date of Patent: August 15, 2006Assignee: Halliburton Energy Services, Inc.Inventors: Robert E. Domann, Randy S. Rosine

Patent number: 6968894Abstract: A coiled tubing injector apparatus for use in inserting coiled tubing into a well, temporarily suspending the coiled tubing, and removing the coiled tubing from the well is described. The apparatus includes a base with a pair of spaced-apart carriages extending upwardly therefrom. The base is part of a frame positioned above a wellhead. The carriages each have a gripper chain drive system rotatably mounted thereon and movable therewith. An actuation and linkage system allows the carriages to move toward and away from one another in a lateral or transverse direction with respect to the superstructure and the base. Thus, the gripper chain systems comprises gripper chains that can be engaged or disengaged from the coiled tubing extending through the apparatus. A wetting fluid basin is positioned below the gripper chains, and support guides engage the coiled tubing below the gripper chains to prevent buckling of the coiled tubing.Type: GrantFiled: February 17, 2004Date of Patent: November 29, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Larry L. Austbo, Randy S. Rosine, Robert E. Domann, Kenneth C. Parks
