Figure F14. Summary of logs recorded by the Formation MicroScanner (FMS)-sonic tool string, Hole U1394B. Hole size is measured by the two orthogonal calipers of the FMS (C1 and C2). Gamma ray recorded during the FMS-sonic run (FMS) is compared to gamma ray recorded by the triple combo run (TC). The high waveform coherence, in red in the velocity tracks, is a measure of the reliability of the slowness/time coherence algorithm used to derive compressional (VP) and shear (VS) wave velocities from the monopole and lower dipole sonic waveforms, respectively.
