  • Telluric noise cancellation in induced polarization prospecting
    Patent number: 4339720
    Abstract: Apparatus and method for generating a record of telluric noise which is substantially free of induced polarization signals and is suitable for removal of noise components from induced polarization signal records. The apparatus includes a single pair of telluric noise sensing electrodes positioned in alignment with, but substantially beyond the ends of, a somewhat conventional induced polarization electrode spread. The method includes recording of telluric noise occurring at the time of detection of induced polarization signals and the subtraction of a fraction of the telluric noise record from the induced polarization signal records.
