P-wave S-Wave Velocity PS Logging
SUSPENSION PS Logger and Sidewell PS Logging
PS Logging is widely used to measure seismic Velocity with three axial geophones generated by the source which was lowered into borehole via armored suspension cable. It is used to acquire high resolution P and S-wave data from borehole to 60m and 120m deep
There are 3 type borehole geophone can be chose (three axial geophones ) with below specification:
