05065819 is referenced by 101 patents and cites 23 patents.

The disclosure describes an electromagnetic apparatus, and a method of use thereof, for simultaneously generating near-uniform heating in a subsurface formation and simultaneously recovering organic and inorganic materials through the apparatus itself. The apparatus may be constructed from flexible or semi-rigid materials for use in horizontal borehole applications. The disclosure also describes a phase-modulated multiple borehole system, and a method of use thereof, for heating larger subsurface volumes and for creating steerable and variable heating patterns. The apparatus and system described herein may be used for recovering oil trapped in rock formations and for decontaminating a region of the earth contaminated with hazardous materials.
