Downhole Shear Wave Velocity Services

by Ninyo & Moore     based in San Diego, CALIFORNIA (USA)

This method is a variation of the seismic refraction method employing a downhole tri-axial geophone and a surface energy source or a downhole source. The energy propagates from the source to the downhole tri-axial geophone and can be recorded as compression and/or shear waves. This method provides detailed layer velocity information and the data ...
