ABSTRACT:
Seismic traces are singularly acquired, digitally converted, normalized according to mean and amplitude, visually displayed for qualitative evaluation, and recorded in conjunction with relevant environmental (acquisition) details. Related pairs of data with differential vertical offsets so recorded are digitally bandpassed according to user specification, limits of dominant waveforms determined with respect to time, crosscorrelated to determine time offset, and average waveform velocity estimated over the depth increment under study, based on the determined time offset and the estimated waveform travel path distance difference.
