Abstract: A tubing wet mate sub is secured to a string of tubing within the well, the wet mate sub having a tubing electrical wet mate connection secured to a lower motor power cable extending from the tubing electrical wet mate connection alongside the tubing to a wellhead. An electrical submersible pump assembly has at least one pump, an upper motor and a lower motor, the lower motor having a lower motor electrical wet mate connection in electrical engagement with the tubing electrical wet mate connection to supply power to the lower motor. An upper motor power cable is connected to the upper motor and extends through the tubing to the wellhead to supply power to the upper motor.

Abstract: An electric submersible pump (ESP) system that is installed in a well to lift fluids out of the well. In one embodiment, the system includes an electric drive positioned at the surface of a well, an ESP positioned downhole in the well, and a cable coupled to carry power from the drive to the ESP. The ESP has a motor that may be either a rotary or linear motor. The stator has magnet coils that may be formed by carbon nanotube conductors. In an inductive rotary motor, carbon nanotube conductors to form the rotor bars and/or conductive end plates of the rotor. The power cable coupling the electric drive to the ESP motor may use carbon nanotube conductors to carry power to the motor, and may also use carbon nanotube strength members to carry the weight of the cable and ESP.
