WebThe crosshole geophysical technique allows the velocities of the primary and secondary waves, P and S, to be obtained along direct paths between two points. Each point located at the same depth inside a different borehole. In one of the borehole the energy source (emitter borehole) is located and in the other the geophone (receiver borehole). WebBorehole Methods. The seismic crosshole method is used determine the shear (S) and compressional (P) wave velocities at two or three adjacent borehole locations. The crosshole method works on the basis of measuring the transit time of P and S-waves generated in one borehole to geophones located at the same depths in one or two nearby …
