A coupling assembly comprising a coupling, a thrust pin, and a retainer ring mechanically couples the first drive shaft to the second drive shaft. The coupling is generally cylindrical in shape with splines formed along the inner surface configured to transfer torque from the first shaft to the second shaft. The thrust pin is installed in a pin bore in the lower shaft and extends into a retainer bore in the upper shaft. The retainer ring is installed between a groove in the retainer bore and a retainer groove on the outside of the thrust pin. The thrust pin is configured to transfer tensile stress from the retainer bore in first drive shaft to the pin bore in the second drive shaft.Type: GrantFiled: April 28, 2022Date of Patent: February 20, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Casey Laine Newport, David McManus, Steven Andrew Lovell, Andre Joseph Bernier

Patent number: 11905803Abstract: Methods and systems for producing hydrocarbons. An example method includes producing a non-hydrocarbon liquid from a first horizontal wellbore, the first horizontal wellbore extending from a vertical wellbore and through a hydrocarbon producing formation. The method further includes pumping the non-hydrocarbon liquid with a first pump into a second horizontal wellbore, the second horizontal wellbore extending from the vertical wellbore and disposed downhole and underneath the first horizontal wellbore. The method additionally includes pumping a hydrocarbon liquid uphole to a surface with a second pump disposed downhole of the first horizontal wellbore.Type: GrantFiled: March 5, 2021Date of Patent: February 20, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Donn J. Brown, Trevor A. Kopecky

Patent number: 11905804Abstract: Techniques for treating a hydrocarbon reservoir include delivering a composition to the hydrocarbon reservoir. The composition includes at least one acid, and liquid or supercritical carbon dioxide (CO2). The method further includes exposing the delivered composition to water to activate the composition; and treating a rock formation of the hydrocarbon reservoir with the activated composition.Type: GrantFiled: June 1, 2022Date of Patent: February 20, 2024Assignee: Saudi Arabian Oil CompanyInventors: Katherine Leigh Hull, Amy J. Cairns, Rajesh Kumar Saini

Patent number: 11905805Abstract: Systems and methods involve capturing gaseous and liquid byproducts from the recovery of hydrocarbons and then using those captured byproducts for commercially and environmentally advantageous purposes. A method for recovering hydrocarbons from a well includes the steps of placing the well in a first mode of operation in which gases from the well are stored under pressure in a gas storage unit on the surface, and placing the well in a second mode of operation in which gases are transferred from the gas storage unit into an underground gas storage formation through the well. Methods for managing produced water include the steps of storing the produced water in an underground water storage reservoir, heating the produced water with geothermal energy, and transferring the heated water to an energy recovery system to generate electricity from the heated produced water.Type: GrantFiled: November 13, 2021Date of Patent: February 20, 2024Assignee: Baker Hughes OilfieldInventors: Mahendra Joshi, Alireza Shahkarami, Rob Klenner

Patent number: 11905806Abstract: A hydraulic fracturing system includes a support structure having a first area at a first height and a second area at a second height, the first and second areas adjacent one another. The system also includes an electric powered, multi-plunger pump with an odd number of plungers, arranged in the first area, the electric powered pump coupled to a well, via outlet piping, and powered by at least one electric motor, also arranged in the first area. The system further includes a variable frequency drive (VFD), arranged in the second area, connected to the at least one electric motor, the VFD configured to control at least a speed of the at least one electric motor. The system also includes a transformer, arranged in the second area, the transformer positioned within an enclosure with the VFD, the transformer distributing power to the electric pump.Type: GrantFiled: October 4, 2022Date of Patent: February 20, 2024Assignee: U.S. Well Services, LLCInventors: Lon Robinson, Jared Oehring, Brandon N.

Patent number: 11905807Abstract: A method includes determining a free water level in the reservoir, analyzing a free water pressure trend of the free water phase, determining a presence of anomalous pressures and salinities within the free water phase, determining whether gas down to models and water up to models fit the reservoir, determining a bi-modal pore throat distribution of the plurality of pores within the reservoir, and generating a difference map to model the water distribution in the reservoir.Type: GrantFiled: June 30, 2021Date of Patent: February 20, 2024Assignee: SAUDI ARABIAN OIL COMPANYInventors: Ahmed Moustafa Abdel Wahab M. Kassem, Nawaf Abdulrahman A Alghamdi, Badr Saeed Badghaish

Patent number: 11905808Abstract: A thermal fluid generator utilizes a plasma energy heat source to generate steam, and combine the steam with nitrogen gas. Combined flow streams of steam and heated nitrogen are injected downhole into subterranean reservoir to thermally stimulate the flow of hydrocarbons (such as, for example, residual oil) from a reservoir, while also increasing fluid pressure in the reservoir. The thermal fluid generator can be located at the earth's surface, or positioned downhole within a wellbore.Type: GrantFiled: March 14, 2022Date of Patent: February 20, 2024Assignee: VIPERA INC.Inventor: James Landry

Patent number: 11905809Abstract: A system can determine a heterogeneity and a score for a reservoir for optimizing a drilling location. The system can receive a wireline log associated with a well that is positioned in a subterranean formation that includes a reservoir. The system can determine, using the wireline log, at least one statistical parameter for an interval of the well. The system can determine, using the at least one statistical parameter, a vertical heterogeneity of the reservoir. The system can determine, using the vertical heterogeneity, a score associated with the reservoir. The score can indicate an extraction difficulty and a carbon intensity of the reservoir. The system can output the score for optimizing a drilling location.Type: GrantFiled: February 24, 2022Date of Patent: February 20, 2024Assignee: Landmark Graphics CorporationInventors: Andrew Davies, Michael Simmons, Lawrence Cowliff, Estanislao Nicolás Kozlowski
