  • Electric power grid induced geophysical prospecting method and apparatus
    Patent number: 7248052
    Abstract: A geophysical prospecting method and apparatus that utilizes the harmonics and sub harmonics waves induced into the earth by the electric power grid. The amplitude-frequency data are converted to amplitude-depth data and further converted to a differential curve. The resulting differential curve is compared to known patterns of the interested geological features, such as hydrocarbon reservoir, to identify whether the features exist and at what depth such geological features lie.
    Type: Grant
    Filed: May 28, 2003
    Date of Patent: July 24, 2007
    Inventors: W. Barry Weaver, Roy K. Warren
  • Electric power grid induced geophysical prospecting method and apparatus
    Patent number: 7227362
    Abstract: An underground prospecting method and apparatus that utilizes the harmonics and fractional harmonic waves induced into the earth by the electric power grid. The data are converted to amplitude-depth and phase-depth data. The resulting data may be plotted and are compared to known patterns of the interested underground features, such as hydrocarbon, water, minerals and cavities, to identify whether the features exist and at what depth such underground features lie.

  • Soil moisture tube extraction device
    Patent number: 5072981
    Abstract: A versatile device is provided for securely gripping the outer surface of a cylindrical object and pulling it against a resistant force comprising a sleeve that fits around the cylindrical object and engages its outer surface with gripping jaws when a pulling force is applied. The extractor enables efficient and economical extraction of soil access tubes without tube damage. The device can be operated either with large power equipment or with a manual jack.
