Abstract
Borehole acoustic data need to be processed to determine the formation waves’ velocity. Here we present some of the most commonly used methods to extract the different modes and to determine the formation velocities. In the early history of acoustic logging, where there were a few receivers in the array, the arrival times were used for velocity determination. With digital recording and expanded arrays, elaborate methods were developed.
