Abstract :
A new method based on the predicting of phase difference (PPM) is developed to extract phase slowness from multi-channel dispersive waves. This method is verified by synthesized multipole array waveforms and field data measured by a multipole array acoustic logging tool (MPAL). The results show that this method is fast and stable for dispersion analysis.
