Patent number: 11795781Abstract: A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.Type: GrantFiled: March 11, 2021Date of Patent: October 24, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Edward George Parkin, Michael Pearce, Julien Steimetz, Jonathan D. Marshall, D. Peter Johnson, Clint William Philbrick

Patent number: 11788359Abstract: A downhole steering system includes a substantially tubular housing, a shaft positioned within the substantially tubular housing, a first bearing and a second bearing, the first and second bearings being configured to support rotation of the shaft relative to the housing. The first bearing, the second bearing, the shaft, and the housing at least partially define a chamber therebetween. The system also includes at least one structure positioned axially between the first and second bearing and being configured to extend from an exterior of the housing in response to pressure communicated to the chamber.Type: GrantFiled: September 13, 2021Date of Patent: October 17, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jonathan D. Marshall, Edward George Parkin, Geoffrey Charles Downton, David C. Hoyle, Nalin Weerasinghe, Dennis Patrick Chesnutt

Patent number: 11767723Abstract: A downhole transducer assembly capable of being safely operated at a variety of pressures and depths may include a turbine rotatable by a fluid pressure differential rotationally fixed to a rotor in a generator. To reduce the rotational speed of the turbine and rotor, a pressure regulator may limit a fluid pressure differential by controlling the volumetric flow. One or more nozzles may be configured to automatically regulate a nozzle diameter, and therefore the pressure drop across the nozzle. A surge protector may be connected to the generator.Type: GrantFiled: October 17, 2021Date of Patent: September 26, 2023Assignee: Schlumberger Technology CorporationInventors: Edward George Parkin, Scott Richard Woolston, Jonathan D. Marshall, David C. Hoyle, Jim Shumway

Patent number: 11753907Abstract: A downhole tool includes a housing and a housing chamber. The housing chamber is separated from a fluid chamber by a seal. The seal maintains a pressure differential between the housing chamber and the fluid chamber. A pressure adjuster between the housing chamber and the fluid chamber maintains the pressure differential below a maximum pressure differential.Type: GrantFiled: April 30, 2020Date of Patent: September 12, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Edward George Parkin, Julien Steimetz, Cecily Millwater, Michael Pearce

Publication number: 20230125784Abstract: A pressure pulse generator and an RSS may change the pressure of a fluid flow through a BHA. If the dogleg at the BHA is less than a target dogleg, then the pressure pulse generator goes into pass-through mode to increase the pressure at the RSS and thereby increase a pad force of the RSS steering pads, increasing the severity of the dogleg. If a downhole tool is stuck, then the pressure pulse generator and the RSS are simultaneously actuated to unstick the downhole tool. The RSS is used to generate and transmit pressure pulses to a downhole tool.Type: ApplicationFiled: October 20, 2022Publication date: April 27, 2023Inventors: Edward George Parkin, Christopher Rowe, Cecily Millwater

Patent number: 11634951Abstract: Aspects of the disclosure relate to a system including an implement (e.g., a steering tool, a drill bit) tetherable to an equipment string (e.g., a drill string), where the implement includes a steering mechanism to steer the equipment string with respect to a wall of a tubular passage (e.g., a borehole). The system can also include a bearing housing for the equipment string (e.g., connectable to a drill pipe of the drill string), where the bearing housing is rotationally coupled with the implement and rotated. The system can further include an actuation mechanism coupleable between the bearing housing and the steering mechanism to actuate the steering mechanism based upon a rotational orientation of the bearing housing with respect to the steering mechanism.Type: GrantFiled: August 3, 2022Date of Patent: April 25, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Edward George Parkin
