Figure F47. Stacked sonic waveforms. Examples of the problem encountered by the P-wave labeling algorithm in "slow" sediments where the formation velocity approaches those of the drilling mud (left and center) and good picking in a more consolidated formation (right). The black solid lines represent the results of the wave labeling algorithm.
