  • In situ processing of organic ore bodies
    Patent number: 4320801
    Abstract: A method and apparatus for fracturing and/or heating subsurface formations wherein an alternating current electric field is produced in the frequency range between 100 kilohertz and 100 meghertz between electrodes spaced apart in the formation and a radio frequency generator supplying a voltage between said lines with suitable loading structures tuned to the frequency of the generator to resonate the electrodes as a parallel wire transmission line which is terminated in an open circuit and produces a standing wave having a voltage node at the end of the line.
    Type: Grant
    Filed: November 29, 1979
    Date of Patent: March 23, 1982
    Assignee: Raytheon Company
    Inventors: Howard J. Rowland, Joseph T. deBettencourt
