Publication number: 20200217184Abstract: An electric motor is configured to be positioned in a well. The motor includes a housing flooded with an incompressible fluid, a seal, a stator in the housing, and a rotor-impeller. The housing is configured to affix to a tubing of the well. The housing defines an inner bore having an inner bore wall continuous with an inner wall of the tubing for flow of well fluid. The housing defines a port that can be in fluid communication with the well. The seal seals the port against ingress of fluid. The seal is movable by the well fluid to apply a pressure on the incompressible fluid to equalize pressure between the incompressible fluid and the well fluid. The rotor-impeller is configured to be positioned within the inner bore of the housing. The rotor-impeller is configured to be retrievable from the well while the stator remains in the well.Type: ApplicationFiled: January 3, 2019Publication date: July 9, 2020Applicant: Upwing Energy, LLCInventors: David Biddick, Patrick McMullen
