FULL WAVEFORM SONIC (FWS)
Full Waveform Sonic (FWS) is a geophysical measurement of sound properties in open-hole, fluid filled formations. Designed specifically for mining and geotechnical applications, acoustic energy is transmitted through borehole fluid into the surrounding rock from the piezoelectric transducer. The acoustic signals are then sensed by the receivers, digitized and transmitted to the surface electronics. Acoustic waveforms can be viewed and processed for amplitude and travel time ( velocity) information.
