Abstract

Systems and methods for producing hydrocarbons from a subterranean well include an electrical submersible pump assembly with a motor, where the motor has a stator located within a motor housing. The stator has a stator body with an interior cavity. A rotor assembly is located within the interior cavity of the stator. The rotor assembly includes a rotor shaft, a rotor member, and an intermediate rotor bearing assembly. A liner is located along an interior surface of the interior cavity, the liner being a thin walled member that is secured to the motor housing and seals the stator body from a wellbore fluid. A rotor cavity is located within an inner bore of the liner. A membrane is located within the liner, the membrane formed of a material operable to bind a component of the wellbore fluid. A hydrophobic fluid is circulating within the rotor cavity.
