Pore structure model for elastic wave velocities in fluid-saturated sandstones
 During hydrostatic compression conducted within the elastic regime, P and S-wave velocities measured on porous rock samples generally increase with pressure and reach asymptotic values at high pressures. The increase in velocities can be attributed to the gradual closure of compliant cracks, in which case the high-pressure velocities reflect only the influence of the stiff, non-closable pores. A procedure is presented to extract the complete pore aspect ratio distribution from the pressure...[Show more]
