Abstract:
A system and method are provided that use RF energy to enhance the extraction of oil and gas from hydrocarbon bearing strata. A three-dimensional underground electromagnetic array is used to guide RF energy to where that energy is convened to heat in the hydrocarbon bearing strata. The three dimensional underground electromagnetic array is a guided wave structure, as opposed to an antenna structure, to minimize the unwanted effects of the near fields associated with antennas. In one embodiment, the legs of the three-dimensional underground electromagnetic array are composed of production well pipe.
