ABSTRACT:
A system and method is provided for heating fluid to be pumped by an electrical submersible pumping system. Heat for heating the fluid may be inductively generated by adjusting the power delivered to the motor of the pumping system. In one example, the power adjustment includes supplying the voltage applied to the pump motor to a value less than voltage applied during normal operations. While lowering the voltage the electrical frequency may be varied as well as the electrical waveform.
