Gassmann-consistency of velocity-porosity transforms

Abstract

Rock physics results have shown that the effective elastic moduli, and thus the seismic velocity of rock, depend on the porosity, lithology, and pore fluid. Laboratory experimentation has resulted in several deterministic porosity-velocity transforms or models for siliciclastic rocks. The development of these models led to the interpretation of petrophysical properties, porosity in particular, from seismic velocity data.
