The actuating system actuates the drive system, which in turn drives the cutting system. In one aspect, the drive system is a rotary motor and shaft system that is connected to the cutting system.Type: ApplicationFiled: April 4, 2003Publication date: March 11, 2004Applicant: Weatherford/Lamb Inc.Inventors: Cecil G.

Publication number: 20040045715Abstract: A method of removing a gravel packed screen to reach another zone is described. The method involves a bottom hole assembly comprising an isolation device for the screen and a tool to latch on to it. A perforating gun is shot off to put holes in the screen to allow gravel to come through. A flow through a reversing valve is initiated to urge the gravel into the newly perforated screen while a vibrator shakes the screen and stimulates gravel flow through the screen. Alternatively, the screen is not isolated and a reverse circulation from the surface in conjunction with vibration urges the gravel to flow through the screen and out through the tubing supporting the bottom hole assembly.Type: ApplicationFiled: September 10, 2002Publication date: March 11, 2004Inventors: Carl W. Stoesz, DAVID B HAUGHTON, JAMES A SONNIER, GERALD D. LYNDE, JOSEPH P. DEGEARE

Publication number: 20040045716Abstract: An arrangement by a hydraulic jar device, especially for use in underground wells, where the jar device is installed in a pipe string led down into the well, and designed so that e.g. a stuck object in the well may be loosened or broken up by upward or downward percussions from the jar device. The jar device is actuated by increasing the flow of drill fluid. Alternatively, the device is actuated by compression. A valve (27, 37, 38) closes off the flow of drill fluid, whereby a percussion cycle is initiated. The valve is designed so as also to seal during strong lateral accelerations.Type: ApplicationFiled: July 3, 2003Publication date: March 11, 2004Inventor: Stig Bakke

Publication number: 20040045717Abstract: The present invention generally relates to methods and apparatus for connecting tubulars and reforming the connection between the tubulars. In one aspect of the invention, the tubulars are aligned, connected, and then reformed at the connection. In one embodiment, the reforming is accomplished by removing material from the tubular connection. Preferably, a broach is used to remove the material. In another embodiment, a reforming member operatively connected to a telescoping tubular is inserted into the tubulars.Type: ApplicationFiled: September 5, 2002Publication date: March 11, 2004Inventors: David M. Haugen, Doyle F. Boutwell

Publication number: 20040045718Abstract: An apparatus and method for forming or repairing a wellbore casing, a pipeline, or a structural support. An expandable tubular member is radially expanded and plastically deformed by an expansion cone that is displaced by hydraulic pressure. Before or after the radial expansion of the expandable tubular member, a sliding sleeve valve within the apparatus permit a hardenable fluidic sealing material to be injected into an annulus between the expandable tubular member and a preexisting structure.Type: ApplicationFiled: January 22, 2003Publication date: March 11, 2004Inventors: David Paul Brisco, Edwin Arnold Zwald, Chan Daigle, Gregory Noel, William J.

Publication number: 20040045719Abstract: A method and apparatus for propelling a tool having a body within a passage. The tool includes a gripper including at least a gripper portion which can assume a first position that engages an inner surface of the passage and limits relative movement of the gripper portion relative to the inner surface. The gripper portion can also assume a second position that permits substantially free relative movement between the gripper portion and the inner surface of the passage. The tool includes a propulsion assembly for selectively continuously moving the body of the tool with respect to the gripper portion while the gripper portion is in the first position. This allows the tool to move different types of equipment within the passage. For example, the tool advantageously may be used in drilling processes to provide continuous force to a drill bit. This enables the drilling of extended horizontal boreholes.Type: ApplicationFiled: July 22, 2003Publication date: March 11, 2004Inventors: Norman Bruce Moore, Ronald E. Beaufort, Rudolph E. Krueger

Publication number: 20040045720Abstract: The invention relates to a tubing expansion tool and to a method of expanding tubing. In one embodiment, a tubing expansion tool (10) is disclosed which comprises a body (14) and at least one expansion member (16) radially movably mounted on the body (14) for movement towards an extended configuration describing an expansion diameter for expanding tubing (12) to a predetermined diameter, the expansion member (16) being lockable in the extended configuration. In further embodiments, the expansion member (16) is biased radially inwardly; the expansion member (16) is moveable in response to both an applied mechanical force and an applied fluid pressure force; and the expansion member (16) is pivotably mounted with respect to the body (14).Type: ApplicationFiled: September 10, 2003Publication date: March 11, 2004Applicant: Weatherford/Lamb, Inc.Inventor: Andrew Michael Duggan
