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.

Claim (Index 9):
The system of  claim 1 , further comprising:\n a second primary-phase dielectric spacer connected to said second primary-phase well pipe segment; a third primary-phase well pipe segment connected to said second primary-phase dielectric spacer such that said second primary-phase dielectric spacer is disposed between said second primary-phase well pipe segment and said third primary-phase well pipe segment; a second primary-phase RF transmission line segment operable to transmit the first RF signal; a second primary-phase well pipe segment switch having a third input port, a seventh output port, an eighth output port and a ninth output port, said second primary-phase well pipe segment switch being operable to be in a third primary-phase well pipe segment state so as to electrically connect said third input port with said seventh output port and said eighth output port and operable to be in a fourth primary-phase well pipe segment state so as to electrically connect said third input port with said ninth output port; a second secondary-phase dielectric spacer connected to said second secondary-phase well pipe segment; a third secondary-phase well pipe segment connected to said second secondary-phase dielectric spacer such that said second secondary-phase dielectric spacer is disposed between said second secondary-phase well pipe segment and said third secondary-phase well pipe segment; a second secondary-phase RF transmission line segment operable to transmit the second RF signal; and a second secondary-phase well pipe segment switch having a fourth input port, a tenth output port, an eleventh output port and a twelfth output port, said second secondary-phase well pipe segment switch being operable to be in a third secondary-phase well pipe segment state so as to electrically connect said fourth input port with said tenth output port and said eleventh output port and operable to be in a fourth secondary-phase well pipe segment state so as to electrically connect said fourth input port with said twelfth output port, wherein said third primary-phase well pipe segment and said third secondary-phase well pipe segment form a third two-wire transmission line when said second primary-phase well pipe segment switch is in the third primary-phase well pipe segment state and when said second secondary-phase well pipe segment switch is in the third secondary-phase well pipe segment state.
