Keywords: semblance, dispersive wave analysis, acoustic logging
Аnnotation: A computer implementation of the method of dispersive semblance for multi-element wave acoustic logging is proposed. The correction matrix for dispersion is constructed in (f-p)-domain using sets of dispersion curves of the flexural wave or Stoneley wave. The matrix is applied in computing scheme of the conventional semblance method in (tau-p)-domain (the Matlab script is given in electronic appendix).
