ABSTRACT:
A slotted radiating unit is lowered into a well casing of limited cross section, and microwave energy is fed downwardly thereto via a transmission line also installed in the casing. Two embodiments of the radiating unit are disclosed, and two embodiments of the transmission line are also described. Depending upon the subterranean conditions, periods of on and off microwave propagation are sometimes employed; in some instances dual radio frequencies are utilized to enhance petroleum flow. Subsurface sensors are made use of to control the ground level radio frequency generator (or generators).
