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 10):
A method comprising:\n providing a first well pipe including a first primary-phase well pipe segment, a primary-phase dielectric spacer, a second primary-phase well pipe segment, a primary-phase RF transmission line segment, a primary-phase well pipe segment switch, the primary-phase dielectric spacer being connected to the primary-phase well pipe segment, the second primary-phase well pipe segment being connected to the primary-phase dielectric spacer such that the primary-phase dielectric spacer is disposed between the first primary-phase well pipe segment and the second primary-phase well pipe segment, the primary-phase RF transmission line segment being operable to transmit a first RF signal, the primary-phase well pipe segment switch having a first input port, a first output port, a second output port and a third output port, the primary-phase well pipe segment switch being operable to be in a first primary-phase well pipe segment state so as to electrically connect the first input port with the first output port and the second output port and operable to be in a second primary-phase well pipe segment state so as to electrically connect the first input port with the third output port; providing a second well pipe including a first secondary-phase well pipe segment, a secondary-phase dielectric spacer, a second secondary-phase well pipe segment, a secondary-phase RF transmission line segment, a secondary-phase well pipe segment switch, the secondary-phase dielectric spacer being connected to the first secondary-phase well pipe segment, the second secondary-phase well pipe segment being connected to the secondary-phase dielectric spacer such that the secondary-phase dielectric spacer is disposed between the first secondary-phase well pipe segment and the second secondary-phase well pipe segment, the secondary-phase RF transmission line segment being operable to transmit a second RF signal, the secondary-phase well pipe segment switch having a second input port, a fourth output port, a fifth output port and a sixth output port, the secondary-phase well pipe segment switch being operable to be in a first secondary-phase well pipe segment state so as to electrically connect the second input port with the fourth output port and the fifth output port and operable to be in a second secondary-phase well pipe segment state so as to electrically connect the second input port with the sixth output port; providing the first RF signal to the primary-phase RF transmission line segment; and providing the second RF signal to the secondary-phase RF transmission line segment, wherein the primary-phase well pipe segment and the secondary-phase well pipe segment form a first two-wire transmission line when the primary-phase well pipe segment switch is in the first primary-phase well pipe segment state and when the secondary-phase well pipe segment switch is in the first secondary-phase well pipe segment state, and wherein the second primary-phase well pipe segment and the second secondary-phase well pipe segment form a second two-wire transmission line when the primary-phase well pipe segment switch is in the second primary-phase well pipe segment state and when the secondary-phase well pipe segment switch is in the second secondary phase well pipe segment state.
