We investigate the effects of permeability, frequency, and fluid distribution on the viscoelastic behavior of rock. The viscoelastic response of rock to seismic waves depends on the relative motion of pore fluid with respect to the solid phase. Fluid motion depends, in part, on the internal wave‐induced pore pressure distribution that relates to the pore micro‐structure of rock and the scales of saturation. We consider wave‐induced squirt fluid flow at two scales: (1) local microscopic flow at… Expand
Elastic wave velocities in partially saturated rocks: Saturation hysteresis
An effective medium approach (differential self-consistent scheme) has been used to calculate elastic wave velocities in rocks containing spherical pores and ellipsoidal cracks with two fluid phases.Expand

Summary The effect of single-phase fluid saturation on the seismic bulk modulus of a rock is well understood; however, the behavior becomes more complex when multiple fluids are present. SeveralExpand
Bounds on low‐frequency seismic velocities in partially saturated rocks
The most common technique for estimating seismic velocities in rocks with mixed pore fluid saturations is to use Gassmann’s relations with an effective fluid whose density and compressibility areExpand

TLDR
The results suggest that a high permeability network of sediments or fractures in a lower permeability host rock may have a distinct separable attenuation signature, even if the overall volume of high permeable material is low. Expand
Impact of flow-simulation parameters on saturation scales and seismic velocity
Scales of fluid saturation below seismic resolution introduce uncertainties in the interpretation of seismic velocity. A “coarse‐scale” or “patchy” distribution always has a higher effective seismicExpand

Elastic modeling of seismic wave propagation in partially saturated rocks
Summary The effect of single-phase fluid saturation on a rock’s bulk modulus is well understood using Gassmann’s equation. However when multiple fluids are involved the behaviour is not as wellExpand
