ABSTRACT:
A technique of heating a subterranean oil bearing formation comprises determining a thermal harmonic frequency of the formation and applying a form of alternating current to the formation that includes the thermal harmonic frequency to increase the temperature of the formation. Heated oil is produced from the formation. A standard three phase ac power source is converted to dc and then chopped to single phase ac so substantially all of the purchased power can be delivered to the well.
