Patent number: 11761280Abstract: A downhole tool including a mandrel having a first surface, and opposing second surface defining a flow path, a lock support zone provided one of the first and second surfaces, and a passage extending between the flow path and the first surface. A tool is supported on one of the first and second surfaces. A sleeve is selectively shiftable on the one of the first and second surfaces into engagement with the tool. The sleeve includes a first surface portion and a second surface portion. The second surface portion includes a latch section. A lock system is arranged between the first surface and the second surface portion in the lock support zone. The lock system includes a lock member selectively supporting a lock element in the latch section. The lock element constrains movement of the sleeve.Type: GrantFiled: November 29, 2021Date of Patent: September 19, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Gregory Hern, Christopher Hern

Publication number: 20230105819Abstract: A guide assembly including a guide nose, a body supporting the guide nose, and a torque limiter having a configuration to connect the guide nose and the body to a separate structure. A method for negotiating a restriction in a borehole including running a guide assembly into the borehole, encountering a restriction with the guide nose, limiting torque on the guide nose while encountering the restriction, longitudinally unloading the guide nose, incrementing an incrementing feature of the guide assembly to thereby rotate the guide nose. A wellbore system including a borehole in a subsurface formation, a string in the borehole, a guide assembly disposed within or as a part of the string.Type: ApplicationFiled: August 18, 2022Publication date: April 6, 2023Applicant: Baker Hughes Oilfield Operations LLCInventors: Christopher Hern, Marc Samuelson, Shane Harris
