Patent number: 11808110Abstract: A technique facilitates actuation of a downhole device, such as an isolation valve. According to an embodiment, the downhole device may be in the form of an isolation valve member, e.g. a ball valve element, actuated between positions by a mechanical section which may comprise a shifting linkage. Actuation of the mechanical section, and thus actuation of the isolation valve member, is achieved by a trip saver section controlled according to a pressure signature which may be applied from a suitable location, e.g. from the surface. The trip saver section comprises a housing having an internal actuation piston coupled with the mechanical section. The trip saver section further comprises a pilot piston and a plurality of chambers formed in a wall of the housing and arranged to enable shifting of the actuation piston in response to a predetermined series of pressure pulses or other suitable pressure signature.Type: GrantFiled: April 21, 2020Date of Patent: November 7, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Cassius Elston, Thomas Meeks, Venkata Siva Reddy Battula, Ashish Sharma

Patent number: 11788362Abstract: A drill bit and method incorporate backup assemblies that limit depth of engagement of cutters with the formation. The backup assemblies dynamically adjust exposure relative to a cutting profile in response to downhole loading conditions. In an example, cutters are secured to the cone, nose, shoulder, and/or gage regions of the bit body. One or more backup assemblies are provided on the cone, nose, or shoulder region, and optionally, on the gauge region. A backup element on an outwardly facing end of the piston limits a depth of cut of one or more of the cutters. The backup element may be rigidly secured or rotatably secured to the piston. The piston may be biased outwardly to a neutral position aligned with or overexposed relative to the cutting profile.Type: GrantFiled: December 15, 2021Date of Patent: October 17, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Kevin Clark, Kelley Plunkett, Andrew D.

Patent number: 11788378Abstract: A system includes a ball valve positionable along a fluid flow path of a wellbore. The ball valve is movable between an open position, where fluid is able to flow through the fluid flow path, and a closed position, where the fluid is prevented from flowing through the fluid flow path. The system also includes an electric motor coupled to a drive system within a trunnion of the ball valve. The electric motor drives rotation of the ball valve to move the ball valve between the open position and the closed position. Further, the system includes a power source electrically coupled to the electric motor to provide power to the electric motor.Type: GrantFiled: January 24, 2019Date of Patent: October 17, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Darrin Nathaniel Towers, Kenneth Lemoine Schwendemann, Benjamin Thomas Derryberry

Patent number: 11788363Abstract: A clamp assembly, for mounting around a tool joint coaxially joining cylindrical upper and lower workpieces, comprises an upper collar assembly and a lower collar assembly, each having semi-cylindrical left and right collar segments. The left and right collar segments of each collar assembly are removably connectable to each other by threaded fasteners to form the collar assembly. The upper and lower collar assemblies are coaxially mountable around the upper and lower workpieces, respectively, such that tightening the fasteners will urge the upper and lower collar assemblies to grip the upper and lower workpieces, respectively, and thus to provide increased resistance to relative rotation between the two workpieces about the tool joint axis. The upper and lower left collar segments, and/or the upper and lower right collar segments, may be interlockingly and radially slidable relative to each other to accommodate differences between the outside diameters of the two workpieces.Type: GrantFiled: April 5, 2021Date of Patent: October 17, 2023Assignee: Noetic Technologies Inc.Inventors: Maurice William Slack, Victor Yung

Patent number: 11732550Abstract: An electro-hydraulic control system actuates a control valve. A control module is controlled via two hydraulic lines and two electrical power lines. The control module uses one of the hydraulic lines as a “supply” line and the other line as a “return” line. The control module includes two normally closed (NC) solenoid valves (SOVs) that are coupled to the electrical power lines and can be controlled from the surface to open or close. The opening or closing of the NC SOVs in cooperation with hydraulic pressure on a “supply” line of the hydraulic lines operates the control valve. A NC hydraulic activated pilot cartridge in the control module can be actuated open, and movement of the control valve in either direction can continue for a short time without energizing either of the NC SOVs, therefore lowering a power demand required by the system.Type: GrantFiled: December 20, 2021Date of Patent: August 22, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Lorenzzo Breda Minassa, Robert William Gissler
