Patent number: 11795808Abstract: A method comprises operating an electric submersible pump (ESP) motor downhole in a well. The ESP motor is electrically connected to a variable speed drive (VSD) proximate to the well. The operating comprises measuring a revolution rate and a motor current of the ESP motor for a first period of time and performing a first adjustment of a voltage output of the VSD. The method comprises measuring, after the first adjustment, the revolution rate and the motor current of the ESP motor for a second period of time determining a difference between the motor current measured for the first period of time and the motor current measured for the second period of time; and performing a second adjustment of the voltage output of the VSD based on a change in the revolution rate and the motor current between the first period of time and the second period of time.Type: GrantFiled: February 6, 2023Date of Patent: October 24, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Luke Golden Janger, Ryan Bridwell Ashbaugh, David Linn Self, Wesley John Nowitzki, David C.

Patent number: 11480047Abstract: One or more sensors are mounted on a collar proximate to a motor shaft of a motor. The motor is associated with an electric submersible pump (ESP) located in a wellbore of a geological formation. The one or more sensors sense one or more identifiers located on the motor shaft of the motor. One or more of a rotation direction and rotation speed of the motor shaft is determined based on the sensing of the one or more identifiers. The motor is powered to pump fluid from a reservoir in the geological formation to a surface of the geological formation based on the one or more of the rotation direction and rotation speed of the motor shaft.Type: GrantFiled: December 28, 2018Date of Patent: October 25, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Tyler Clay Courtwright, Ryan Bridwell Ashbaugh, Dustin Campbell, Carl Albert Palmgren, III

Patent number: 11466547Abstract: Permanent magnet motors (PMMs) can develop oscillations during motor startup that can cause damage to electric submersible pump (ESP) components. A system and method are presented for identifying mechanical and/or electrical caused oscillations in a PMM through the analysis of oscillations in current and torque measurements. A control system within a surface motor controller receives current and/or torque measurements from downhole sensors. The control system employs one or more algorithms designed to detect oscillations in the measurements. Upon detecting oscillations that are consistent with oscillations in the motor from mechanical or electrical causes, the control system automatically initiates protective action to prevent damage to the ESP components.Type: GrantFiled: October 31, 2019Date of Patent: October 11, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Ryan Bridwell Ashbaugh, David C.

Patent number: 11391096Abstract: An electric submersible pump used to pump fluids inside a borehole during operation is described. The electric submersible pump and its motor can be powered using an inductive power coupling. The electric submersible pump comprises a sealed extension that houses a pickup inductive coil assembly that is electrically coupled to a power source at a surface of the borehole. Power runs through the primary inductive coil assembly and the primary inductive coil is positioned relative to the pickup inductive coil assembly such that the electrical current flowing in the primary inductive coil assembly from the power source and through the power cable induces a voltage in the pickup inductive coil assembly.Type: GrantFiled: December 20, 2019Date of Patent: July 19, 2022Assignee: Halliburton Energy Services, Inc.Inventors: David Christopher Beck, Walter Dinkins, Ryan Bridwell Ashbaugh, Robert Charles De Long

Patent number: 11248459Abstract: Selectively automating the powering of downhole equipment during run-in-hole (RIH) operations provides a means of safely installing and monitoring downhole equipment. Selective automation comprises monitoring lowering of a pump assembly into a borehole as part of an installation process. In response to determining that the lowering of the pump assembly into the borehole has stopped, an output of power from a power source to a cable coupled to the pump assembly is allowed. A data transmission is communicated from a downhole gauge in the pump assembly to a communication device at a surface of the borehole via the cable. In response to not receiving a valid data transmission at the communication device, it is determined that the cable may be damaged, and that further cable testing should occur.Type: GrantFiled: March 26, 2020Date of Patent: February 15, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Carl Albert Palmgren, III, Ryan Bridwell Ashbaugh, Mark Dale Stewart
