Patent number: 11255153Abstract: A seal apparatus and method of use is described. The seal apparatus comprises a seal assembly comprising a plurality of elements assembled together to form a ring structure around a longitudinal axis. The ring structure is operable to be moved between an expanded condition and a collapsed condition by movement of the plurality of elements. The plurality of elements is operable to be moved between the expanded and collapsed conditions by sliding with respect to one another along respective contact surfaces. Each of the plurality of elements is a compound element comprising a substrate and at least one seal member disposed on a part of a surface of the element.Type: GrantFiled: June 28, 2018Date of Patent: February 22, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Gareth Edward George Brown

Patent number: 11231077Abstract: A torque transfer apparatus and method of use is described. The apparatus comprises a plurality of elements assembled together to form a ring structure oriented in a plane around a longitudinal axis. The ring structure defines a first engagement surface. A structure defining a second engagement surface is rotatable with respect to the ring structure. The ring structure is operable to be moved between a collapsed condition and an expanded condition by movement of the plurality of elements, and movement between the collapsed condition and the expanded condition engages or disengages the first and second engagement surfaces.

Patent number: 7510002Abstract: An improved valve for sealing a wellbore and method of use, in particular for prevention of well blow outs. In one embodiment, the apparatus is designed to seal a well through rotation of rams. The rams may be actuated to seal the well without having to work against full well pressure as fluid volumes in the apparatus housing, which also contains the rams, are preserved. This functionality allows the apparatus to be constructed with smaller dimensions than existing prior art blow out prevention valves aiding handling and manoeuvrability. The improved valve according to one embodiment also has a mechanism that guides a wireline or a pipeline being run in the wellbore to the centre of the bore and allows a seal to be formed around the wireline or pipeline.Type: GrantFiled: March 2, 2005Date of Patent: March 31, 2009Assignee: Hunting Cromar LimitedInventors: Gareth Edward George Brown, Frederick Duguld McKay, Colin Alexander Black
