Patent number: 6209634Abstract: 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 carriages extending upwardly therefrom. The base is attached to a superstructure. 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 can be engaged or disengaged from tubing extending through the apparatus. Each of the carriages are pivotally attached to the base with a load pin which extends through lugs attached to the base and corresponding lugs extending down from the carriage.Type: GrantFiled: April 26, 1996Date of Patent: April 3, 2001Assignee: Halliburton Energy Services, Inc.Inventors: Vladimir A. Avakov, William D. Taliaferro, Malcolm N. Council

Patent number: 5775417Abstract: The coiled tubing handling apparatus includes a base and a frame. First and second pairs of plate members are coupled to the frame. A drive sprocket and an idler sprocket are coupled to the first pair of plate members for supporting a first continuous gripper chain with gripper members for movement along a first path. A drive sprocket and an idler sprocket are coupled to the second pair of plate members for supporting a second continuous chain with gripper members for movement along a second path. A drive system is provided for moving the gripper chains together along the two paths for gripping and moving a tube. Two pairs of idler sprockets are coupled to each of the first and second pairs of plate members for supporting a linear bearing chain within each of the two gripper chains. A linear bearing race engages each linear bearing chain for causing the two linear bearing chains to engage the two gripper chains respectively for causing the two gripper chains to move linearly along the first and second paths.Type: GrantFiled: March 24, 1997Date of Patent: July 7, 1998Inventor: Malcolm N.

Patent number: 5553668Abstract: A twin carriage coiled tubing injector apparatus for use in inserting coiled tubing into a well, temporarily suspending the coiled tubing, and removing the tubing from the well. The apparatus includes a superstructure with a pair of spaced carriages disposed therein. The carriages each have a gripper chain drive system rotatably mounted thereon and movable therewith. An actuation and linkage system allows the carriage to be moved toward and away from one another in a transverse direction with respect to the superstructure. This movement allows gripper chain systems to be engaged or disengaged from tubing extending through the apparatus. A roller chain system is disposed in each of the carriages and is adapted for engagement and support of the gripper chain systems as the gripper chain systems are engaged with the tubing. A timing gear system may optionally be provided to insure that the rotational speed of the gripper chain systems are substantially constant.Type: GrantFiled: July 28, 1995Date of Patent: September 10, 1996Assignee: Halliburton CompanyInventors: Malcolm N. Council, Carl H. Johnson

Patent number: 5244046Abstract: A coiled tubing service unit and method for oil and gas wells including a string of components extending above ground in coaxial alignment with said well and including an injector for injecting coiled tubing into the well and a sealing unit for preventing the flow of pressurized oil and gas from the well. The sealing unit is adapted to be disconnected from the string of components and removed from the coaxial alignment to permit a relatively large-diameter tool assembly to be inserted therein. The sealing unit can then be repositioned and connected in the string of components and the coiled tubing can be reinserted into the string, connected to the tool and driven into the well.Type: GrantFiled: August 28, 1992Date of Patent: September 14, 1993Assignee: Otis Engineering CorporationInventors: Malcolm N. Council, William H. McCormick

Patent number: 5191173Abstract: An electrical cable assembly (10) comprising a cable core (12) and filler layer (16) encased in longitudinally welded reeled tubing (23) so as to restrict relative axial and longitudinal motion between the cable core (12) and reeled tubing (23). Small-diameter tubing (24) is optionally provided as part of the cable core (12) to facilitate the delivery of fluids such as lubricants and corrosion inhibitors to downhole equipment. A method is disclosed for deploying electrical cables in deep wells through use of the subject apparatus.Type: GrantFiled: April 22, 1991Date of Patent: March 2, 1993Assignee: Otis Engineering CorporationInventors: Phillip S. Sizer, Malcolm N. Council, Willard J. Deese, E. G. Hoffman, Robert F. Bailey, David H. Neuroth

Patent number: 4945938Abstract: A large diameter reel having a large diameter hollow drum with a flange at each end about which a flexible elongate member, such as coil tubing, electrical conductor cable, or the like, may be wound, the reel having no shaft, but instead, having a large central opening extending therethrough, and having a gear located in the opening or on at least one or both of the reel's flanges. A carrier, such as a skid, trailer or semi-trailer, is provided with rollers for supporting the reel upon edge and with a driving gear meshable with the reel gear for rotating the reel. The trailer or semi-trailer may be provided with a hole in the bed thereof to accommodate the reel in an inset position to permit such vehicles with a reel thereon to freely pass beneath highway overpasses, and other overhangs. Methods of supporting such reels on such carriers are also provided.Type: GrantFiled: September 22, 1989Date of Patent: August 7, 1990Assignee: Otis Engineering CorporationInventors: George L. Ponsford, William H. McCormick, Malcolm N. Council, Albert W. Carroll

Patent number: 4919204Abstract: Apparatus for pressurized cleaning of well flow conductors. The apparatus has a non-rotating inner mandrel, an adapter to connect the inner mandrel to a work string, a rotating housing on the exterior of the inner mandrel, and a nozzle body attached to the housing. An alternative embodiment of the invention allows cleaning tools to be attached to a modified nozzle body and rotated therewith. Fluid pressure flowing through the inner mandrel will cause the housing to rotate relative to the inner mandrel. Rotation is used to direct fluid jets in the nozzle body towards different portions of the interior of the flow conductor. Rotation of a cleaning tool can also be used for combined mechanical and hydraulic drilling to remove deposits from within a well flow conductor.Type: GrantFiled: January 19, 1989Date of Patent: April 24, 1990Assignee: Otis Engineering CorporationInventors: Walter Baker, Malcolm N. Council

Patent number: 4781250Abstract: Apparatus for pressurized cleaning of flow conductors. The apparatus has a first mandrel and a second mandrel telescoped therein. A cleaning tool can be attached to the second mandrel. Changes in fluid pressure flowing through the mandrels will cause the second mandrel to rotate relative to the first mandrel. Rotation is used to direct fluid jets in the cleaning tool towards different portions of the interior of the flow conductor. Rotation of the cleaning tool can also be used for hydraulic drilling of deposits within the flow conductor.Type: GrantFiled: December 14, 1987Date of Patent: November 1, 1988Assignee: Otis Engineering Corp.Inventors: William H. McCormick, Charles C. Cobb, Malcolm N. Council
