Patent number: 10995972Abstract: A geo-energy production system and method extracts thermal energy from a reservoir formation, and stores either thermal waste heat or excess heat in a storage zone of the reservoir formation. A compressed fluid injection injects an unheated, compressed working fluid into the storage zone. A fluid injection well injects a working fluid laden with thermal waste heat or excess heat into the storage zone. The storage zone is located below a caprock layer and above a native brine zone of the reservoir formation and is partially circumscribed by a hot brine storage zone. The compressed working fluid assists with a withdrawal of pressurized brine residing below and/or to the sides of the storage zone. A compressed CO2, N2, or air production well helps to remove compressed working fluid from the storage zone for use in power production.Type: GrantFiled: July 5, 2017Date of Patent: May 4, 2021Assignee: Lawrence Livermore National Security, LLCInventor: Thomas A.

Patent number: 10975682Abstract: Systems and methods for determining the resistance of a power cable of an ESP. The nameplate resistance of the motor is determined prior to installation of the ESP in the well, and the temperature is determined for a point in the well at which the motor will be positioned. The downhole temperature and nameplate resistance are used to calculate an initial downhole resistance of the motor. After the ESP is installed, but before operation of the ESP is initiated, the electric drive for the system generates a measurement voltage and applies the measurement voltage to the power cable and motor. The corresponding current is then measured and is used to calculate the resistance of the string (the combined power cable and motor). The calculated initial downhole resistance of the motor is then subtracted from the resistance of the string to obtain the resistance of the power cable.Type: GrantFiled: May 2, 2018Date of Patent: April 13, 2021Assignee: BAKER HUGHES, A GE COMPANY, LLCInventor: Nathan A Etter

Patent number: 10883349Abstract: A wellbore completion is configured for multiple forms of artificial lift. A downhole assembly on production tubing defines a production port communicating a throughbore with the wellbore annulus. A bypass, such as a snorkel or riser tube, on the assembly also communicates the throughbore between the packer and the production port with the annulus. A packer on the assembly seals in the annulus downhole of the production port and bypass. The assembly can then be configured for any selected artificial lift. To do this, at least one isolation (a sleeve insert, a sliding sleeve, a check valve, or a rupture disk) selectively prevents/allows communication via one or both of the production port and the bypass as needed. Additionally, removable lift equipment, including jet pump, gas lift valve, plunger assembly, rod pump, piston pump, or standing valve, is selectively inserted into the assembly's throughbore as needed.Type: GrantFiled: September 22, 2017Date of Patent: January 5, 2021Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Thomas Scott Campbell, Manish Agarwal, Jeffrey J.
