Patent number: 11619108Abstract: A bridge plug includes a splayable assembly. The splayable assembly includes an upper annulus with upper extensions, a lower annulus with lower extensions opposing the upper annulus along an axis extending through the upper annulus and the lower annulus, and a linkage connecting the lower annulus to the upper annulus. The linkage has an upper link pivotably connected to a lower link, the upper link pivotably connected between circumferentially adjacent upper extensions and the lower link pivotably connected between circumferentially adjacent lower extensions. The elastic barrier sleeve extends circumferentially about the splayable assembly such that movement of the lower annulus towards the upper annulus expands the elastic barrier sleeve to form a barrier within a wellbore. Bridge plug arrangements and methods of emplacing bridge plugs in wellbores are also described.Type: GrantFiled: September 19, 2018Date of Patent: April 4, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Jack Gammill Clemens, Anthony Phan, Mark Holly

Patent number: 11506014Abstract: A ferromagnetic fluid can be used to provide a temporary barrier in a wellbore. A magnetic sub can generate an electromagnetic field within the wellbore. The ferromagnetic fluid is retained at a desired location within the wellbore by the electromagnetic field. Ferromagnetic particles in the fluid can clump together or settle to form the temporary barrier. A zonal isolation fluid such as a metallic fluid, a cement composition, or a curable resin composition can be introduced on top of the temporary barrier. The zonal isolation fluid can solidify to form a permanent or semi-permanent barrier to provide zonal isolation of different zones of the subterranean formation.Type: GrantFiled: July 8, 2021Date of Patent: November 22, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Wei Zhang, Mark Holly

Patent number: 11236565Abstract: A setting tool and bridge plug that are run-in-hole on wireline through a core bit while drill rods are in place can be used to plug a borehole. A setting tool can be sized to have a same or smaller diameter as a drill rod. A bridge plug can have a run-in configuration of a diameter that is smaller than an inner diameter of a core bit. The bridge plug can have a set configuration that can respond to the setting tool pulling uphole. The bridge plug can be positioned below a drill bit of the drill rod in the set configuration, and the diameter of the bridge plug in the set configuration can be greater than the diameter of the drill rod.Type: GrantFiled: May 7, 2018Date of Patent: February 1, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Robert Alexander Petrie, Michael John Houston, Mark Holly, Jack Gammill Clemens, Grant Spark

Patent number: 11162313Abstract: An anchor for a linear actuator includes a body, a mandrel with at least two slip-receiving portions, and one or more slips. The body can be coupled to the linear actuator and the mandrel can be coupled to the power rod of the linear actuator. The linear actuator can power on and cause the power rod to move in an uphole direction toward the linear actuator. Moving the power rod can cause the mandrel to move in an uphole direction. The slip can respond to the mandrel moving in an uphole direction by expanding outward. The mandrel can continue to move in the uphole direction until the slip is received at a second slip-receiving portion.Type: GrantFiled: May 30, 2018Date of Patent: November 2, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Jack Gammill Clemens, Mark Holly, Nathan J.

Patent number: 10760373Abstract: Disclosed embodiments include a retrievable bridge plug assembly. The retrievable bridge plug assembly includes a sealing element that is elastically deformable to expand radially outward when the sealing element experiences axial compression and at least one anti-extrusion device positioned downhole from the sealing element. The at least one anti-extrusion device includes a shoulder that in operation maintains contact with the sealing element. Also included in the at least one anti-extrusion device is a plurality of anti-extrusion petals positioned downhole from the shoulder that expand radially outward from the anti-extrusion device. Additionally, the at least one anti-extrusion device includes an expandable sleeve surrounding the plurality of anti-extrusion petals that covers extrusion gaps of the plurality of anti-extrusion petals when the plurality of anti-extrusion petals expand radially outward from the anti-extrusion device.Type: GrantFiled: April 6, 2017Date of Patent: September 1, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Anthony Phan, Jack Gammill Clemens, Mark Holly

Patent number: 10590731Abstract: Assemblies and methods are provided for retrieving a sealing assembly from within a tubing string positioned downhole in a wellbore. The sealing assembly may include a plug that may include a non-elastomeric material at least partially surrounding an elastomeric material. The sealing assembly may be run downhole in the wellbore with the plug at an original diameter. The sealing assembly may be set such that the plug is expanded to a set diameter. The retrieval tool may be coupled to the sealing assembly and may be extended in a first direction. The extension of the retrieval tool may lengthen the sealing assembly. The lengthening of the sealing assembly may extend the length of the plug and may thereby reduce the diameter of the plug. In some aspects, the retrieval tool may reduce the diameter of the plug back to the original diameter.Type: GrantFiled: September 28, 2017Date of Patent: March 17, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Jack Gammill Clemens, Anthony Phan, Mark Holly

Patent number: 10557327Abstract: A bridge plug for a well includes an actuator member that moves from a first position such that the bridge plug is in a retracted position and a second position such that the bridge plug is in a deployed position. The bridge plug includes a slip section comprising one or more slips that grip a surface radially outward of the bridge plug in the deployed position and a petal section positioned downward of and adjacent to the slip section, the petal section comprising a plurality of petals that fan radially outward from the bridge plug in the deployed position to catch a slurry. The bridge plug also includes a centralizer section positioned downward of and adjacent to the pedal section, the centralizer section having a plurality of centralizers that ramp outwardly in an upward direction in the deployed position for centralizing the bridge plug.Type: GrantFiled: September 22, 2016Date of Patent: February 11, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Jack Clemens, David Larimore, Mark Holly

Patent number: 8602115Abstract: A tractor configured for grip locking during advancement to avoid slippage, particularly in open-hole wells. The tractor is equipped with a grip lock mechanism for independently locking an anchor grip in a radially outward direction. This locking occurs sequentially in advance of the power stroke of a reciprocating drive piston associated with the anchor. Thus, radial outward expansion and gripping are ensured at the time pulling of a load in an axial downhole direction is pursued. Such grip locking may be employed throughout tractoring or intermittently, depending upon well characteristics such as formation hardness and well diameter.Type: GrantFiled: December 1, 2009Date of Patent: December 10, 2013Assignee: Schlumberger Technology CorporationInventors: Franz Aguirre, Wade D.
