Patent number: 11525346Abstract: A method of improving natural gas recovery from a subterranean hydrocarbon reservoir includes at least one renewable energy source that is electrically coupled with a heat conducting element. The heat conducting element is positioned in a perforated section of a wellbore that traverses into the subterranean hydrocarbon reservoir.

Patent number: 11506046Abstract: An compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore extending through the carrier from the first end to the second end, forming a carrier wall between the bore and the exterior surface of the carrier. The bore and couplings are offset from a central axis of the carrier (the axis of the cylindrical outer surface of the carrier), resulting in a thicker portion of the carrier wall on one side of the carrier. Cavities are formed (e.g., by drilling holes) within the thicker portion of the carrier wall. One or more sensors and corresponding electronics are then positioned within the cavities, so that the carrier wall itself forms a housing for the sensors and electronics.Type: GrantFiled: December 16, 2020Date of Patent: November 22, 2022Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Yuh Loh, Thomas McClain Scott, James Joseph Freeman, John Raggio, Lorn Rendall

Patent number: 11499411Abstract: There is described a computer-implemented method of controlling a drilling operation. In particular, there is described a computer-implemented method of determining that a differential pressure is in an oscillating state. In response to determining that the differential pressure is in the oscillating state, a weight on bit setpoint is decreased so as to decrease the differential pressure. There is also described a computer-implemented method of determining a difference between a differential pressure and a target differential pressure. The target differential pressure is less than a differential pressure limit. A weight on bit setpoint is adjusted as a function of the difference between the differential pressure and the target differential pressure so as to adjust the differential pressure and thereby reduce the difference between the differential pressure and the target differential pressure.Type: GrantFiled: December 21, 2020Date of Patent: November 15, 2022Assignee: PASON SYSTEMS CORP.Inventors: Kshitij Agarwal, Jonathan Alan McIntyre, Choon-Sun James Ng, Aaron Eddy
