Abstract
An electric submersible pump used to pump fluids inside a borehole during operation is described. The electric submersible pump and its motor can be powered using an inductive power coupling. The electric submersible pump comprises a sealed extension that houses a pickup inductive coil assembly that is electrically coupled to a power source at a surface of the borehole. Power runs through the primary inductive coil assembly and the primary inductive coil is positioned relative to the pickup inductive coil assembly such that the electrical current flowing in the primary inductive coil assembly from the power source and through the power cable induces a voltage in the pickup inductive coil assembly.
