Patent number: 11905802Abstract: An electrical submersible pump assembly comprising a first section and a second section with an outer housing and a drive shaft. 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

Publication number: 20230349273Abstract: An electrical submersible pump assembly comprising a first section and a second section with an outer housing and a drive shaft. A coupling assembly comprising a coupling, a first and a second locking keys, and a plunger assembly mechanically couples the first drive shaft to the second drive shaft. The coupling is cylindrical in shape with splines configured to transfer torque from the first drive shaft to the second drive shaft. The plunger assembly extends the first and second set of locking keys from a key port in the first shaft and second shaft into a groove within the coupling. The coupling assembly is configured to transfer tensile stress from the first drive shaft to the second drive shaft in response to extending the first locking key in the first groove and the second locking key in the second groove of the coupling.Type: ApplicationFiled: April 28, 2022Publication date: November 2, 2023Inventors: David MCMANUS, Steven Andrew LOVELL, Casey Laine NEWPORT, Andre Joseph BERNIER

Publication number: 20220145737Abstract: A thru-tubing conveyed (TTC) pump system comprising a rig-deployed assembly and a TTC removable assembly. The rig-deployed assembly includes a motor and a receiving base. The motor is configured to turn a first shaft, and an end of the first shaft includes a non-circular cross-section in a plane perpendicular to a longitudinal axis of the first shaft. The TTC removable assembly includes an engaging base and a pump, the pump configured to be turned by a second shaft. An end of the second shaft has a non-circular cross-section in a plane perpendicular to a longitudinal axis of the second shaft. The engaging base of the TTC removable assembly engages the receiving base of the rig-deployed assembly when the TTC removable assembly is delivered downhole.Type: ApplicationFiled: November 12, 2020Publication date: May 12, 2022Inventors: Casey Laine NEWPORT, Josh Wayne WEBSTER, Steven Andrew LOVELL, Wesley NOWITZKI
