GeoVista - Full Waveform Sonic Probes

Geovista sonic probes are used to measure sonic velocities as well as the associated sonic waveforms. These data can be used for formation characterisation as well as. The Geovista sonic sondes consist of a ceramic-piezoelectric transmitter and two or four receivers. The larger 60 mm diameter sonde is particularly suited for deployment in large water wells. The slimmer. 50 mm diameter sonde is suitable for the smaller diameter mineral exploration and geotechnical boreholes. For both sondes, the transmitter-receiver combinations allow for the measurement of formation acoustic wave velocities and wave amplitude. The compressional (P) wave arrivals are easily identifiable from GV Full Waveform Sonic data. However, the shear (S) wave arrivals can be identified only under certain suitable borehole and formation conditions.
