Patent number: 11041352Abstract: A system can include an annular restrictor connected in a tubular string. The annular restrictor restricts flow through an annulus formed between the tubular string and a wellbore. Restriction to the flow through the annulus biases the tubular string into the wellbore, and fluid in the wellbore displaces into the tubular string and/or a formation penetrated by the wellbore. A method can include connecting an annular restrictor in a tubular string, and flowing a fluid through an annulus formed between the tubular string and a wellbore, thereby causing a differential pressure across the annular restrictor, the differential pressure biasing the tubular string into the wellbore. Another method can include connecting an annular restrictor in a tubular string, flowing a fluid through an annulus, thereby biasing the tubular string into a wellbore, and then causing the annular restrictor to no longer restrict flow through the annulus.Type: GrantFiled: May 19, 2016Date of Patent: June 22, 2021Assignee: Thru Tubing Solutions, Inc.Inventors: Andrew M. Ferguson, Brock W. Watson, Roger L. Schultz

Patent number: 10329868Abstract: An articulated debris barrier folds on itself to extend radially to span a surrounding annular gap when the tool associated with it is set. The debris barrier can be used with a packer or bridge plug. The set position of the packer or plug is locked and another lock holds the extended position of the debris barrier. The debris barrier lock can be a snap ring that extends into a groove brought into alignment with it during the setting. Alternatively the lock for the debris barrier can be a body lock ring. In either case, release and retrieval of the packer or plug involves undermining of the locking feature for the debris barrier so that the debris barrier can extend while retracting from the borehole wall so that the barrier and the associated packer or plug can be removed together.Type: GrantFiled: August 28, 2015Date of Patent: June 25, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Christopher J. Limb, Frank J. Maenza, Nicholas S. Conner, Robert J. Taylor, Gary L. Anderson

Patent number: 9890603Abstract: A tubing anchor catcher for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotational directions. A mandrel connected to the equipment has one or more grooves for slideably receiving respective drive pins from a drag body on the mandrel. A slip cage on the mandrel houses a slip or slips for selectively engaging and disengaging the conduit. Manipulation of the mandrel at surface causes the drive pins to move within the one or more grooves on the mandrel and the drag body conical surface to move toward the slip cage driving the slip or slips outward to grip the conduit. Further pulling at surface maintains the set position. The anchor is unset at surface by releasing the tension, rotating the mandrel in the second direction, and pulling the mandrel to disengage the slip or slips.Type: GrantFiled: May 6, 2015Date of Patent: February 13, 2018Assignee: Tazco Holdings Inc.Inventors: Edward L. Moore, Christopher S McArthur, Jasen L. Hoffman, Kevin D. Kelm

Patent number: 9719316Abstract: A slip assembly is in two pieces that move relatively to each other to facilitate release. The wicker portion is dovetailed to the base near a center underside location and at the edges. A positive travel stop converts the initial relative movement into tandem movement of the base and the wicker segment after a predetermined relative movement that has resulted in release. Adjacent components prevent relative movement during the radially outward movement for setting the assembly during which there is tandem movement of the base portion and the wicker portion. The two portions can be initially attached with a breakable member that fails during the release movement.Type: GrantFiled: April 10, 2014Date of Patent: August 1, 2017Assignee: Baker Hughes IncorporatedInventor: William C. Lemm

Patent number: 9567822Abstract: A downhole tool has a mandrel with packing elements. Collars between the packing elements define ports communicating with gaps between the packing elements and the mandrels. Opposing piston housings on the mandrel can move in opposing directions to compress the packing elements against the collars. Each piston housing defines a space with the mandrel and has a second port communicating with the gap. Pistons disposed in the spaces are temporarily affixed thereto. Hydraulic pressure communicated through the mandrel's bore acts against the pistons. While affixed to the piston housings, the pistons move the piston housings toward the packing elements to compress then. When the packing elements set, continued pressure breaks shear pins affixing the pistons to the piston housings so the pistons move and eventually seal fluid communication between the second ports in the pistons and the gaps.Type: GrantFiled: March 6, 2014Date of Patent: February 14, 2017Assignee: Weatherford Technology Holdings, LLCInventor: Michael C. Derby

Patent number: 9410412Abstract: An array of plugging devices are pumped sequentially from the surface through a liner that typically becomes horizontal in nature, where each plugging device is anchorable at a specific position along the length of the line. Perforations are generated above the plugging device. The plugging device may be a cup plug and when pump pressure is applied to the cup the cup moves through the liner. When anchored, the cup directs frac fluids through the perforations to treat the well formation. The plug may be of the type where a full bore is maintained through the liner and allows the cup plug to travel back to the surface due to flow from the well thus eliminating any need for milling obstructions from the well bore. The use of multiple plugging devices allows multizone stage fracing.Type: GrantFiled: March 21, 2013Date of Patent: August 9, 2016Assignee: Completion Tool Development, LLCInventor: Gregg W. Stout

Patent number: 6536532Abstract: A selectively released well packer is set between a pair of anchor shoe assemblies. Each assembly comprises a tubular setting sleeve having finger projections meshed with an anchor shoe cage. Wicker shoes are confined by the shoe cage. The packer seal and shoes are set by an axial translation of one shoe cage toward the other driven by a hydraulic sleeve piston. The packer is released by cutting the mandrel and pulling up on the tubing string. The uphole shoe cage is secured to the mandrel with limited axial freedom. Upward translation of the uphole portion of the severed mandrel therefore disengages the uphole anchor shoes and the packer seal. A buttress thread section of the mandrel engages a corresponding thread on the downhole setting sleeve to sequentially release the downhole anchor shoe.Type: GrantFiled: March 1, 2001Date of Patent: March 25, 2003Assignee: Baker Hughes IncorporatedInventor: James Christopher Doane
