Publication number: 20240087828Abstract: Microelectromechanical systems (MEMS) switches are disclosed. Parallel configurations of back-to-back MEMS switches are disclosed in some embodiments. An isolation connection of constant electrical potential may be made to a midpoint of the back-to-back switches. In some embodiments, a separate MEMS switch is provided as a shunt switch for the main MEMS switch. MEMS switch device configurations having multiple switchable signal paths each coupling a common input electrode to a respective output electrode are also disclosed. The MEMS switch device includes shunt switches each coupling a respective output electrode to a reference potential. The presence of a shunt switch coupled to an output electrode enhances the isolation of the signal path corresponding to that output electrode when the path is open.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Analog Devices International Unlimited CompanyInventors: Padraig Fitzgerald, Philip James Brennan, Jiawen Bai, Michael James Twohig, Bernard Patrick Stenson, Raymond C.

Patent number: 10822899Abstract: A technique facilitates use of a liner hanger in a wide variety of environments by distributing loading. The liner hanger may comprise a liner hanger cone, e.g. an annular cone body, having a plurality of slots for receiving corresponding pipe-gripping slips. The slip slots and the corresponding pipe-gripping slips are staggered both longitudinally and circumferentially to distribute loading. An actuator may be used to shift the slips into gripping engagement with a surrounding pipe, e.g. casing, to improve the load distribution on the surrounding pipe and liner hanger cone once the liner is supported.Type: GrantFiled: September 23, 2016Date of Patent: November 3, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Travis Raymond Burke, James Hall, Raghavendar Ranganathan, Srihari Chebolu

Patent number: 10808507Abstract: A technique facilitates actuation and use of a liner hanger in a wide variety of environments. Depending on the application, the liner hanger may be conveyed downhole within a casing located in a wellbore. The liner hanger comprises slips which may be set against the casing by applying a pressurized fluid through a liner hanger port to a liner hanger actuator. After the slips are set, the liner hanger may be actuated to form a metal-to-metal seal which blocks further fluid flow through the port, thus isolating the port during subsequent downhole operations.Type: GrantFiled: September 7, 2016Date of Patent: October 20, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Travis Raymond Burke, James Hall, Raghavendar Ranganathan, Srihari Chebolu

Patent number: 10597986Abstract: A technique facilitates hanging of a liner in a borehole. According to the technique, a liner hanger and a liner may be deployed downhole into a borehole. A wellbore anchoring device of the liner hanger is initially actuated to engage a surrounding surface and to resist downward movement of the liner. Additionally, a hold down anchor is subsequently actuated to resist upward movement of the liner. The hold down anchor may be released via mechanical manipulation of the liner hanger.Type: GrantFiled: August 3, 2016Date of Patent: March 24, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Travis Raymond Burke, James Hall, Raghavendar Ranganathan, Srihari Chebolu, David E.

Patent number: 10570723Abstract: A technique facilitates joining of sections of tubing and related monitoring. An expandable tubular member may be coupled with an external tubing, e.g. a casing. The expandable tubular member is deployed into the external tubing to a desired position. Then, an expandable portion of the expandable tubular member may be plastically deformed in a radially outward direction and into engagement with the external tubing. A sensor system may be combined with the expandable tubular member to monitor a characteristic of the expandable tubular member.Type: GrantFiled: May 23, 2017Date of Patent: February 25, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Travis Raymond Burke, James Hall
