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 1):
A system comprising:\n a first primary-phase well pipe segment; a primary-phase dielectric spacer connected to said first primary-phase well pipe segment; a second primary-phase well pipe segment connected to said primary-phase dielectric spacer such that said primary-phase dielectric spacer is disposed between said first primary-phase well pipe segment and said second primary-phase well pipe segment; a primary-phase RF transmission line segment operable to transmit a first RF signal; a primary-phase well pipe segment switch having a first input port, a first output port, a second output port and a third output port, said primary-phase well pipe segment switch being operable to be in a first primary-phase well pipe segment state so as to electrically connect said first input port with said first output port and said second output port and operable to be in a second primary-phase well pipe segment state so as to electrically connect said first input port with said third output port; a first secondary-phase well pipe segment; a secondary-phase dielectric spacer connected to said first secondary-phase well pipe segment; a second secondary-phase well pipe segment connected to said secondary-phase dielectric spacer such that said secondary-phase dielectric spacer is disposed between said first secondary-phase well pipe segment and said second secondary-phase well pipe segment; a secondary-phase RF transmission line segment operable to transmit a second RF signal; and a secondary-phase well pipe segment switch having a second input port, a fourth output port, a fifth output port and a sixth output port, said secondary-phase well pipe segment switch being operable to be in a first secondary-phase well pipe segment state so as to electrically connect said second input port with said fourth output port and said fifth output port and operable to be in a second secondary-phase well pipe segment state so as to electrically connect said second input port with said sixth output port, wherein said first primary-phase well, pipe segment and said first secondary-phase well pipe segment form a first two-wire transmission line when said primary-phase well pipe segment switch is in the first primary-phase well pipe segment state and when said secondary-phase well pipe segment switch is in the first secondary-phase well pipe segment state, and wherein said second primary-phase well pipe segment and said second secondary-phase well pipe segment form a second two-wire transmission line when said primary-phase well pipe segment switch is in the second primary-phase well pipe segment state and when said secondary-phase well pipe segment switch is in the second secondary-phase well pipe segment state.
