ABSTRACT:
This specification discloses a system and method for processing deconvolved seismic traces to compensate for phase distortion introduced in deconvolving the traces. The method provides for automatically processing the traces in an automatic data processing machine. A filter is generated from the signal pulse of the seismic energy applied to the earth in obtaining the seismic traces and this filter is applied to the deconvolved seismic traces to phase correct the traces.
