AB: A recently developed elastic fluid-flow model accounting for the physical phenomena associated with frequency-dependent anomalous reflectivity at low seismic frequencies is discussed. Besides theoretical calculations, observations from field and laboratory data indicate that the reflectivity is strongly related to the reservoir flow properties. An asymptotic scaling of the frequency-dependent component of the reflection coefficient with respect to the frequency of the signal and the reservoir fluid mobility has been obtained. This scaling incorporates the reservoir fluid mobility. The porous medium tortuosity factor from Biot's equations has been linked to the relaxation time in dynamic Darcy's law.
