Patent number: 10767652Abstract: A permanent magnet submersible motor for electric submersible pump systems and a method of making the rotor of such a motor. The unitary construction of the rotor shaft and the yoke provides improved protection of the damage-prone magnets, while the larger effective shaft diameter also improves shaft bending resistance. Shaped form closures on the yoke promote secure magnet retention, even under highly centrifugal loads, while an exterior cladding tube and a cast resin filler material are used to further secure the magnets around the yoke periphery while also providing hermetic sealing against a working fluid.Type: GrantFiled: December 14, 2016Date of Patent: September 8, 2020Assignee: Flowserve Management CompanyInventor: Michael Klahn

Patent number: 10753166Abstract: A method for installing an electrical submersible pump (ESP) in a well containing a production conduit includes securing an ESP to a lower end of a coiled tubing segment containing an electrical power cable. An operator secures a load transfer device with a gripping member to the coiled tubing segment above the ESP. The operator lowers the coiled tubing segment into the well along with the ESP and the load transfer device. The load transfer device contacts an interior side wall of the production conduit with the gripping member and transfers a load on the coiled tubing segment to the production conduit. When powered, the ESP causes well fluid to flow upward from the ESP through the load transfer device up the production conduit.Type: GrantFiled: September 7, 2018Date of Patent: August 25, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Kenneth O'Grady, John Mack, Sean Cain, James Christopher Clingman

Patent number: 10689957Abstract: The disclosed device provides a high-accuracy plunger arrival detection system comprising a low-power magnetometer with high sensitivity and which is capable of sampling low or high intensity magnetic fields. The device processes gathered data from sensors, stores at least some processed data in memory, executes a trending algorithm which compares the magnetic field of the plunger to the ambient magnetic field or a predetermined set of initialization values, and generates an output which is relayed to a well controller. An output signal may be via hard wire, RF, wireless or other known means. In addition, the implementation of two sensing devices mounted in series and in spaced relation to each other, can provide for an actual plunger average velocity. An actual plunger average velocity, as opposed to approximate average velocity, can be used to better optimize well control and improve safety of the overall well production system.Type: GrantFiled: October 30, 2017Date of Patent: June 23, 2020Assignee: PCS Ferguson, Inc.Inventors: Terry R. Wright, Burke E. Lowery, Paul T. Roberts

Patent number: 10683738Abstract: One illustrative artificial lift method includes deriving compressed natural gas (CNG) from liquefied natural gas (LNG) and employing the CNG to hydraulically drive a downhole pump that forces fluid from the well. An illustrative system embodiment includes an evaporator, a controller, and a downhole pump. The evaporator converts LNG into CNG, which the controller employs to alternately pressurize and depressurize a hydraulic line. The downhole pump includes a plunger that performs a pump stroke in response to the pressurization and a return stroke in response to the depressurization; these pump and return strokes operate to force fluid from a well. Further disclosed herein is the use of a virtual pipeline to supply LNG for such artificial lift systems and methods. It includes: liquefying natural gas to fill a transport trailer at an offsite facility; transporting the trailer to a site of a well; and coupling the trailer to surface equipment.Type: GrantFiled: May 22, 2015Date of Patent: June 16, 2020Assignee: CTLift Systems LLCInventor: Humberto Leniek, Sr.
