Geophysicists have devoted great efforts to the problem of determining fluid saturation from seismic measurements, with some notable successes. It is commonly believed that fluid information is to be found in the P-wave data, with shear waves being insensitive to fluid, and indeed almost all successful fluid-detection methodologies have been based on analysis of the P-wave.
