Patent number: 11035203Abstract: A completion section includes a base pipe defining a central flow passage, an injection port, and a production port. A fracturing assembly includes a frac sleeve positioned within the central flow passage adjacent the injection port, a sensor that detects a wireless signal, a first frac actuator actuatable in response to the wireless signal to move the frac sleeve and expose the injection port, and a second frac actuator actuatable based on the wireless signal to move the frac sleeve to occlude the injection port. A production assembly is axially offset from the fracturing assembly and includes a production sleeve positioned within the central flow passage adjacent the production port, a filtration device arranged about the base pipe, and a production actuator actuatable based on the wireless signal or an additional wireless signal to move the production sleeve to an open position where the production ports are exposed.Type: GrantFiled: October 31, 2016Date of Patent: June 15, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Matthew James Merron, Zachary William Walton, Michael Linley Fripp

Patent number: 11025188Abstract: Systems and methods for determining proper phase rotation in a linear motor that may be used in an ESP system, where the phase rotations associated with power and return strokes are initially unknown. The method includes providing power to the motor for multiple cycles and monitoring the load (e.g., by monitoring current drawn by the motor) on the motor to determine in which direction (phase rotation) the load on the motor increases. This direction corresponds to the power stroke of the motor. The direction of increasing load is then associated with the power stroke and the motor is operated normally.Type: GrantFiled: May 9, 2016Date of Patent: June 1, 2021Assignee: BAKER HUGHES, a GE company, LLCInventor: Renato L.

Patent number: 11015441Abstract: A transmitter is carried proximate to an inground tool for sensing a plurality of operational parameters relating to the inground tool. The transmitter customizes a data signal to characterize one or more of the operational parameters for transmission from the inground tool based on the operational status of the inground tool. A receiver receives the data signal and recovers the operational parameters. Advanced data protocols are described. Pitch averaging and enhancement of dynamic pitch range for accelerometer readings are described based on monitoring mechanical shock and vibration of the inground tool.Type: GrantFiled: March 11, 2019Date of Patent: May 25, 2021Assignee: Merlin Technology, Inc.Inventors: Albert W. Chau, Loc Viet Lam, Scott Phillips

Patent number: 10975678Abstract: A production well apparatus for underground coal gasification and an underground coal gasification method using same. The production well apparatus comprises a well head apparatus, a sleeve (8), a product pipe (1), a coolant pipe (3), and a monitoring meter system (7). Coolant is injected, during underground coal gasification, to be in contact and mixed with product gas, and the product gas is discharged after cooled, such that the operation is safer and more controllable. Moreover, most of the components of the production well apparatus can be completely or partially recycled and reused after the gasification is completed.Type: GrantFiled: August 24, 2016Date of Patent: April 13, 2021Assignee: ZHONGWEI (SHANGHAI) ENERGY TECHNOLOGY CO. LTDInventors: Casper Jan Hendrik Burger, Zhenhua Min, Yuanli Wang

Patent number: 10838101Abstract: An example method includes introducing a solution into at least part of a reservoir. The solution includes a contrast agent and a fluid. The contrast agent includes a polymer having a dielectric constant that may be greater than a predefined value. The example method also includes using at least one EM transmitter antenna to direct a first electromagnetic (EM) signal into the reservoir. The first EM signal passes through the at least part of the reservoir into which the solution was introduced. The first EM signal is received using at least one EM receiver antenna following passage through the at least part of the reservoir. Data is determined that represents a difference between a first travel time of the first EM signal transmitted through the contrast agent in the reservoir and a second travel time of a second EM signal transmitted through water-saturated reservoir rock. Information about a physical feature of the at least part of the reservoir is generated based on the data.Type: GrantFiled: May 23, 2018Date of Patent: November 17, 2020Assignee: Saudi Arabian Oil CompanyInventors: Erika Shoemaker Ellis, Howard Khan Schmidt, Jason Cox, Jesus Manuel Felix Servin
