ABSTRACT:
A method of producing a display of acoustic velocity characteristics of individual strata in a geologic section includes propagating broad-band acoustic energy into the earth, detecting reflected energy from multiple strata at an array of receiving stations, recording the received signals, normalizing the signals representing the energy received from each strata interface for losses due to the strata above that interface to restore the signal levels and to derive a sequence of loss factors, filtering the low frequency signals from the resulting signals, adding to the resulting filtered signals a set of gross velocity profile signals and displaying the results.
