Travel time stacking is a new method for processing and displaying the data from full waveform sonic logs. This technique is much faster than the conventional method of threshold detection followed by correlation (Willis and Tokosz 1983). By stacking the wavetrains from multiple receiver tools along lines of constant travel time, travel time stacking provides the log analyst with a concise and easy-to-use picture of the formation acoustic properties. The travel time stacking method is fast enough to provide an automatic, on-site display of compressional, shear and Stoneley-wave travel times along with a clear picture of data quality and processing reliability.
