Abstract
Systems and methods of enhancing crude oil flow radiate electromagnetic energy in the form of focused far field electromagnetic energy into a permeable formation containing the crude oil so as to cause the oil to decrease in viscosity without a substantial change in temperature of the crude oil, increasing the ability of the oil to flow within the formation toward the well and enabling recovery from the reservoir.
