Patent ID: 8485251

Claim:
A method for enhancing flow of crude oil particles within a select subsurface region separated from a terrain surface via geological strata, the method comprising: positioning a plurality of transmit antennae on or below the terrain surface in a given pattern relative to the select subsurface region targeted for impingement; controllably transmitting from said transmit antennae in the far field only, continuous wave (CW) or pulsed electromagnetic energy beams of given frequency, power, directivity and duration through the geological strata to generate an aggregate magnetic field having an isotropic profile focused onto the select subsurface region containing the crude oil, said electromagnetic energy beams transmitted through the geological strata without losses or interference attributable to the near field effects of the electromagnetic energy beams; wherein the aggregate magnetic field impinges upon the crude oil particles at a target frequency and energy sufficient to decrease the viscosity of said oil particles a given amount to enhance crude oil flow within the select subsurface region.
