Abstract
A method for analyzing received wave signal data in an acoustic logging system that includes a logging tool adapted to be moved through a borehole in the earth and comprising a transmitter section and receiver section, wherein the transmitter section produces sonic waves at periodic intervals which are received as wave signal data by the receiver section. The method comprises the steps of processing the received wave signal data using Fourier Transform procedures, filtering the processed data using a Heisenberg filter procedure, using a Hilbert transform to refine the filtered data, and using the refined data to provide a phase velocity analysis.
