Patent number: 10151163Abstract: A stabilizer system articulates at least one blade independently of an extendable blade for a through tubing mill. The stabilizer can be actuated with flow, pressure or set down weight. A piston responds to flow or pressure from the surface and an elongated member can cam out the stabilizer with set down weight on the extendable blades.Type: GrantFiled: August 22, 2016Date of Patent: December 11, 2018Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Cristian A.

Patent number: 8607858Abstract: A whipstock features a spiral ramp so that, in a horizontal run, access to a milled window with other tools is not impeded because such tools can traverse onto the ramp and still be directed to the window. Angular rotation of the ramp can be at 180° or more and the pitch is selected to avoid getting the equipment being advanced into a bind. Optionally, a guide track can be configured into the whipstock ramp to help the mill follow the spiral path until the proper orientation is obtained and the track ends to allow separation of the mill from the track. A slot can be provided near the ramp upper end to aid in retrieval operations.Type: GrantFiled: November 9, 2011Date of Patent: December 17, 2013Assignee: Baker Hughes IncorporatedInventors: Graeme D. McKay, Christopher W. Guidry, Paul L. Connell, David B. Haughton

Patent number: 8505651Abstract: An anchor system including a housing having a radial opening therein. A piston disposed within the housing and translatable therein. A slip in operable communication with the piston such that translation of the piston axially of the housing causes movement of the slip radially of the housing. The slip having a contact face that is nonparallel to an axis of the housing and nonparallel to a surface against which the slip is configured to be set. A method for anchoring a tool is included.Type: GrantFiled: April 15, 2010Date of Patent: August 13, 2013Assignee: Baker Hughes IncorporatedInventors: Nathan J. Brandt, David B. Haughton, John P.

Publication number: 20100288492Abstract: A debris removal tool uses a screen to separate the debris coming into the tool from the moving fluid. The fluid that gets through the screen then operates a flow sensing device that is preferably a turbine whose speed of rotation or other characteristics of its movement generates a signal that is picked up by the measurement while drilling tool and conveyed to the surface. The surface personnel first respond by turning off surface pumps to allow debris to fall by gravity off the clogged screen. If that fails, the tool is pulled through the well fluid inducing a reverse flow through the screen to get the debris blocking it to go back into the well through the debris removal tool inlet.Type: ApplicationFiled: May 18, 2009Publication date: November 18, 2010Inventors: Michael J. Blackman, Sidney D. Huval, David B. Haughton, James A. Sonnier

Publication number: 20080251254Abstract: Devices and methods for translating tubulars within a wellbore and, as a result, effectively freeing a stuck tubular string within a wellbore. One or more vibrator devices are incorporated into a tubular string, such as a drill string. Each of the vibratory devices may be turned on or off independently, as needed, to help effectively free the tubular string from a stuck condition.Type: ApplicationFiled: April 16, 2007Publication date: October 16, 2008Applicant: Baker Hughes IncorporatedInventors: Gerald D. Lynde, Carl W. Stoesz, David B. Haughton

Patent number: 7234546Abstract: A method and associated equipment are disclosed which allow drilling at least a portion of a well and subsequently cementing casing in a single trip. The method is particularly suited for deep-water offshore operations where the drill string can be run through a section of casing leaving a bit and an under-reamer extending out below. The casing is equipped with ports through which cement can be pumped as well as an external casing packer to prevent the uncured cement in the annulus from U-tubing. Several casing sections can be run in during drilling and cemented succession using the one trip method.Type: GrantFiled: April 2, 2003Date of Patent: June 26, 2007Assignee: Baker Hughes IncorporatedInventors: Ray P. Vincent, Frank Koehrmann, George E. Givens, Christiaan D. Krauss, Edward T. Wood, Friedhelm Makohl, David B. Haughton

Patent number: 6866104Abstract: A downhole vibration tool consisting of a body assembly installed in a work string, and a drop-in dart valve assembly. An open inner bore through the body assembly allows the performance of operations through the body assembly. To activate the vibration tool, the dart valve assembly is dropped into the work string and pumped downhole into engagement with the body assembly. Once the dart valve assembly is in place in the body assembly, continued pumping of fluid will cause the tool to begin to vibrate longitudinally. When the jarring operation is finished, the dart valve assembly can be released from the body assembly and retrieved, with a wireline or coiled tubing unit.Type: GrantFiled: January 28, 2003Date of Patent: March 15, 2005Assignee: Baker Hughes IncorporatedInventors: Carl W. Stoesz, Joe DeGeare, Gerald D. Lynde, Roy E. Swanson, James A. Sonnier, David B. Haughton

Patent number: 6805197Abstract: A combination tool for attaching to a stuck wireline tool, then cutting the wireline just above the stuck tool with a hydraulically driven cutter, allowing the wireline to be pulled out of the hole before fishing out the stuck tool. A side door can be provided on the work string, to allow rerouting of the wireline outside the work string, after which the stuck tool can be unstuck and repositioned within the well bore for completion of the downhole operation of the tool, prior to cutting the wireline free from the downhole tool.Type: GrantFiled: June 18, 2002Date of Patent: October 19, 2004Assignee: Baker Hughes IncorporatedInventors: Kenneth A. Brumley, John P. Davis, Gregory L Hern, David B. Haughton

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

Patent number: 6702031Abstract: A method and apparatus for severing the mandrel of an anchor device such as a packer to release the packer and remove it from a well. A cutter locator profile above the packer assembly and a cutter locator element on the cutting tool are located so as to precisely position the cutting element at a desired location on the packer mandrel. Once the mandrel is severed, the packer assembly can elongate to release the expansion mechanism. Then, the packer assembly can be pulled upwardly to release the packer, and to remove it from the well. A cutting tool can be lowered through production tubing to sever the mandrel, followed by pulling the packer with the production tubing. Alternatively, a cutting tool can be lowered on a workstring and latched to the upper end of the packer assembly, followed by severing the mandrel and pulling the packer with the workstring.Type: GrantFiled: January 31, 2002Date of Patent: March 9, 2004Assignee: Baker Hughes IncorporatedInventors: James C. Doane, Michael Vincent Smith, Roger Steele, John P. Davis, David B. Haughton
