Patent number: 10794174Abstract: A dynamically self-balancing pressurized borehole sealing apparatus and method thereof for coal seam gas pressure measurement having a pressure measuring tube arranged in a borehole with one end of the pressure measuring tube provided with a pressure measuring unit. The pressure measuring tube is wrapped with an expansion airbag and provided with a pressure introducing hole communicating with the expansion airbag. On each side of the expansion airbag, the pressure measuring tube is wrapped with a front borehole inflatable sealing airbag and a rear borehole inflatable sealing airbag respectively. A gel injection chamber is reserved between the front borehole sealing airbag and the rear borehole sealing airbag and between the expansion airbag and an inner side of the borehole. Gas from the pressure measuring tube expands the expansion airbag and squeezes sealing gel in the gel injection chamber into borehole fractures for dynamic pressurized sealing.Type: GrantFiled: July 13, 2018Date of Patent: October 6, 2020Assignee: SHANDONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Wei Lu, Zhen Liu, Guansheng Qi, Jinliang Li, Dongling Sun, Weimin Cheng, Dong Wang, Chuanrui Qin

Patent number: 10794175Abstract: Many monitoring systems, including distributed fiber optic sensing systems, are deployed to measure temperature, strain, acoustic, pressure, and electromagnetic data in a multi-well hydrocarbon field. By coupling disparate fiber optic cables together for strain sensing, a tubular cable is created that can be spooled and deployed as a single unit while allowing for multi-parameter sensing. Multiple tubular cables can measure and transmit sensing data from wellbores and geological formations. The data can be used to continually update a reservoir model and optimize production efficiency while also managing and mitigating subsidence by controlling injection and production rates.Type: GrantFiled: September 2, 2015Date of Patent: October 6, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Mikko Jaaskelainen, Harold Grayson Walters, Ronald Glen Dusterhoft

Patent number: 10794176Abstract: A measurement while drilling system for a drill string having a fluidic medium in the drill string. The measurement while drilling system includes a first module situated at a distal end of the drill string and including a downhole processor and a pulser communicatively coupled to the downhole processor and configured to provide a pressure pulse in the fluidic medium, and a second module situated at a proximal end of the drill string and including an uphole processor and a pressure sensor communicatively coupled to the uphole processor. The downhole processor is configured to direct the pulser to provide the pressure pulse and the pressure sensor is configured to sense the pressure pulse. The uphole processor is configured to receive signals from the pressure sensor to determine a distance from the first module to the second module.Type: GrantFiled: August 5, 2018Date of Patent: October 6, 2020Assignee: Erdos Miller, Inc.Inventors: Kenneth C. Miller, David Erdos, Abraham C. Erdos

Patent number: 10794179Abstract: A method for obtaining hydrocarbon from a reservoir in a subterranean formation can include measuring a poromechanic pressure change due to lithostatic load sharing in the subterranean formation. The poromechanic pressure change can then be mapped to one or more locations within the subterranean formation. Once mapped, the method can identify one or more local pressure peaks in the poromechanic pressure change, wherein each of the one or more local pressure peaks are marked by a pressure escalation and subsequent pressure depletion. The method can then determine one or more regions within the reservoir exhibiting single phase hydrocarbon production.Type: GrantFiled: July 26, 2018Date of Patent: October 6, 2020Assignee: ConocoPhillips CompanyInventors: Samarth Agrawal, Richard A.
