Martinez, D R

The method is described of correcting distorted seismic data obtained by applying seismic energy to the earth's surface and recording a wave trace representative of the resultant reflected seismic energy comprises the steps of: (a) recording a signal representing the ground force produced by the application of the energy wherein the ground force signal is derived from mass and acceleration parameters of an acoustic source used to produce the seismic energy; (b) correlating the ground force signal with a preselected signal pulse and correlating the reflected seismic wave trace with the preselected signal pulse in order to provide time compressed versions of the ground force signal and the reflected seismic wave trace respectively; (c) processing the time compressed ground force signal by means of a preselected technique and processing the reflected seismic wave trace by means of the preselected technique in order to remove distortion therefrom; (d) deriving a correcting filter representing an inverse function of the processed ground force signal; and (e) convolving the correcting filter with the processed reflected seismic wave trace in order to provide a corrected seismic output.
