Downhole Shear Wave Velocity Services
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 can be used to evaluate the compression wave and shear wave velocities of the subsurface soils versus depth. ...
