1. A method for downhole waveform tracking and sonic labeling (classification), said method comprising:

  • a) logging waveform arrival data at a plurality of depths k;

    b) mapping the continuity of the data tracks as a function of slowness or time over depth;

    c) building a probability model of the likely classification of the tracks based on said mapping;

    d) evaluating the probability model with Bayesian analysis to determine the most likely classifications of the tracks.
