Abstract
A system for pumping and heating viscous fluids in a wellbore includes electrical power supplies, a switchboard, conductors, and a submergible pumping system having a pump and a submergible electric motor. The electrical power supplies are coupled to the submergible pumping system through a switchboard and conductors that supply electrical power to the motor. The electrical power supplies provide direct or alternating current and include protective circuitry. The submergible pumping system may be supplied with electrical power to motor stator windings to generate heat to raise the temperature and lower the viscosity of adjacent viscous fluids.
