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 of coupled well pipe segments is used to guide RF energy to where that energy is converted to heat in the hydrocarbon bearing strata. The three dimensional underground electromagnetic array of coupled well pipe segments includes a switch to selectively activate coupled well pipe segments and 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 leas of the three-dimensional underground electromagnetic array are composed of production well pipe.
