Abstract

Continuous mapping of velocity dispersion can provide important information on rock physical properties, and thus is desirable. Here we present a method to continuously measure velocity dispersion using full-waveform multi-channel sonic logging data. This method involves techniques of band-pass filtering, beam forming, and cross-correlation of matrices. Using this method, velocity dispersion profiles of P and Stonely waves are obtained using the field sonic data from 5L-38 Mallik gas hydrate research well. The results match very well with the local geological settings. This further proves the robustness of this method, and demonstrates that continuous mapping of P wave velocity dispersion is potentially a promising tool for reservoir characterization.
