SUBSURFACE MULTIPLE ANTENNA RADIATION TECHNOLOGY (SMART)

TurboShale, Inc., Midval...

1. A method comprising:configuring an antenna system comprising a radio frequency heating antenna attached to a coaxial cable and a first radar antenna array attached to the coaxial cable at a distal end of the radio frequency heating antenna, wherein the radio frequency heating antenna is electrically coupled to a radio frequency generator via the coaxial cable:
inserting the antenna system comprising the radio frequency heating antenna and the first radar antenna array into a subterranean borehole;
guiding the antenna system to a desired location in the subterranean borehole using the first radar antenna array; and
heating, by the radio frequency heating antenna, an area around the desired location in the subterranean borehole using the radio frequency heating antenna to form a heated organic material;
imaging a thermal effect of heating on the heated organic material; and
adjusting at least one of a heating pattern, a heating temperature, and a heating rate of the radio frequency heating antenna by changing at least one of an output power and a frequency of the radio frequency generator.
