Patent ID: 7672193

Claim:
A method of processing acoustic waveform data relating to a subterranean formation, comprising: taking acoustic waveform measurements at one or more depths of a borehole traversing a subterranean formation; on a processor extracting a portion of the acoustic measurements based on predetermined parameters for selecting reflected arrival waves in the acoustic measurements, the extracting comprising processing the waveform measurements for a slowness vs. time (ST) plane, generating a processing window around a portion of the processed waveform measurements in the slowness vs. time (ST) plane based on the predetermined parameters, and extracting the processed waveform measurements in the processing window; on a processor generating time projection of the extracted acoustic measurements versus borehole depth, the generating comprising projecting the extracted acoustic measurements to arrival time domain of the slowness vs. time (ST) plane; and generating an indication or imaging of acoustic reflectors in the formation based on the time projected acoustic measurements.
