FAQ Frequently asked questions Display options. Usually measured in microseconds per foot. First used for seismic-velocity information, it is now used chiefly for estimating porosity and lithology by the empirical Wyllie time-average equation. After filtering, the residual sonic section shows the refracted modes and the leaky modes Fig.
