Patent number: 11015406Abstract: A sensor assembly may include a housing made of a non-magnetic material. The housing may define an interior chamber. A shaft may extend from the housing. A bearing may be positioned around the shaft. An impeller may be positioned around the shaft and the bearing, and the impeller may include a magnetized portion. A sensor may be positioned within the interior chamber and/or proximate the magnetized portion. The sensor may detect the magnetized portion of the impeller to sense a rate of rotation of the impeller. The rate of rotation of the impeller may correspond to changes in flow rate of the fluid. As the flow rate of the fluid, and the rate of rotation of the impeller change in predetermined manners, control signals may be conveyed to activate a tool.Type: GrantFiled: January 22, 2019Date of Patent: May 25, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jacques Orban, R. Craig Boswell, Scott Richard Woolston, Jordan Dane Englund

Patent number: 10947787Abstract: An underreamer for increasing a diameter of a wellbore. The underreamer may include a body having an axial bore extending at least partially therethrough. An electromagnetic activation system may be disposed at least partially within the bore of the body. A valve may be disposed within the bore of the body and coupled to the electromagnetic activation system. The valve may include a mobile element and a static element. The mobile element may be coupled to the electromagnetic activation system and move from a first position where the mobile element obstructs fluid flow through the valve to a second position where the mobile element permits fluid flow through the valve. A cutter block may be movably coupled to the body and move radially-outward as the mobile element moves from the first position to the second position.Type: GrantFiled: January 10, 2019Date of Patent: March 16, 2021Assignee: SMITH INTERNATIONAL, INC.Inventors: Nathan E. Fuller, Jonathan D. Marshall, Jordan D. Englund, Jacques Orban, R. Craig Boswell

Patent number: 10683895Abstract: Aspects of the disclosure can relate to an apparatus including a first member having a first bearing surface formed from a hard material (e.g., a diamond-based material, such as a polycrystalline diamond material), and a second member coupled to an input shaft to translate (e.g., rotate, slide, etc.) with respect to the first member. The second member has a second bearing surface formed from a hard material, and the second bearing surface is to bear against the first bearing surface. In embodiments of the disclosure, the first and second members can be for devices including, but not necessarily limited to: solenoids, generators and/or motors (e.g., out-runner radial flux generators, axial flux generators, radial flux generators/motors, roller vane motors, etc.), gearboxes, rotary data swivels, digital actuators, filters (e.g., inner rotating filters), valves (e.g., proportional valves), sensors (e.g., pressure differential sensors), and so forth.Type: GrantFiled: July 19, 2018Date of Patent: June 16, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David R. Hall, Jonathan D. Marshall, Scott S. Dahlgren, Daniel Manwill, R. Craig Boswell, Scott Richard Woolston
