Abstract
A well logging tool employing at least one transmitter and at least one receiver is incrementally advanced through a borehole. A plurality of recorded well log traces from successive ones of the incremental depth points for a single transmitter-receiver pair are correlated to identify a moveout trend for the recorded waveforms about the measured arrival time of the waveform on the center trace of such plurality of traces. A second correlation of the center trace of the plurality of traces with the next successive depth trace is carried out in accordance with the identified moveout trend to determine the arrival time of the acoustic waveform on such next successive depth trace with respect to the measured arrival time of the center trace.
