seismic methods


The Cross-Hole technique is part (with the Down-Hole technique) of the borehole seismic surveys. The main difference between them is the location of the geophones and the seismic source. In the Cross-Hole technique the seismic source it´s on one borehole and the geophones are located in another one adjacent. As a result, the seismic waves velocities (VP and VS) can be obtained, which can be used to compute the main elastic moduli (Poisson’s ratio, Young`s modulus, Shear Modulus and Bulk Modulus).
