Publication number: 20250105763Abstract: An energy harvester, including a cyclical impulse device, and a piezoelectric generator deformably connected to the device. A method for harvesting energy from a flowing fluid including inducing a selected flow regime, causing a cyclical impulse device to cycle based upon the flow regime, and physically deforming a piezoelectric generator with the device. A wellbore system, including a borehole in a subsurface formation, a string in the borehole, and an energy harvester disposed within or as a part of the string.Type: ApplicationFiled: September 27, 2023Publication date: March 27, 2025Inventors: Christopher Hern, Daniel C. Ewing, Andrew Duggan, Ronnie Russell, Kamalesh Chatterjee, Carl Stoesz

Publication number: 20250092763Abstract: An energy harvester arrangement including a housing, a port in the housing, a first member whose position relative to the housing depends upon a Bernoulli effect on the member from a fluid flow through the port, and a piezoelectric voltage generator operably connected to the member. A method for generating electricity, comprising flowing a fluid past a member, the fluid creating pressure change dependent upon flow velocity, causing a movement of the member by the pressure change, physically deforming a piezoelectric generator with the movement, and generating a voltage with the deforming. A system including a structure having a flow path for a fluid, an energy harvesting arrangement, disposed within at least a portion of the flow path. A borehole system, including a borehole in a subsurface formation, a string in the borehole, and an arrangement disposed within or as a apart of the string.Type: ApplicationFiled: September 20, 2023Publication date: March 20, 2025Inventors: Ronnie Russell, Kamalesh Chatterjee, Daniel Ewing, Christopher Hern, Andrew Duggan, Aaron C. Hammer, Izhar Ahmad, Stewart Blake Brazil

Publication number: 20240376803Abstract: An energy harvester, including a housing, an impeller supported in the housing, an agitator operably connected to the impeller, and a piezoelectric member supported by the housing, the member deflectable by the agitator due to rotation of the impeller. A method of generating power from a flowing fluid, including rotating an impeller with the flowing fluid, actuating an agitator with the impeller, and deflecting a piezoelectric member with the agitator. A borehole system, including a borehole in a subsurface formation, a string in the borehole, and an energy harvester disposed within or as a part of the string.Type: ApplicationFiled: May 8, 2023Publication date: November 14, 2024Inventors: Christopher Hern, Daniel Ewing, Andrew Duggan, Ronnie Russell, Kamalesh Chatterjee, Scott P.

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
