Seismic wave attenuation and dispersion resulting from wave-induced flow in porous rocks—A review
One major cause of elastic wave attenuation in heterogeneous porous media is wave-
induced flow of the pore fluid between heterogeneities of various scales. It is believed that …

An overview of laboratory apparatuses to measure seismic attenuation in reservoir rocks
Intrinsic wave attenuation at seismic frequencies is strongly dependent on rock permeability,
fluid properties, and saturation. However, in order to use attenuation as an attribute to extract …
