Abstract

The present invention imparts heat to the targeted area through the application of carefully controlled radiofrequency transmissions. The technology is applied by inserting a flexible coaxial transmission line and applicator (antenna) system into multiple vertical or horizontal boreholes in the area to be treated. Radiofrequency generators supply energy through coaxial lines to multiple electromagnetically coupled down-hole antennas, and the subsurface material between the antennas rises in temperature as it absorbs radiofrequency energy radiating from the antennas.
