Seismic wave attenuation and dispersion due to wave-induced fluid flow in rocks with strong permeability fluctuations
(Acoustical Society of America Institute of Physics, 2013-06)
Oscillatory fluid movements in heterogeneous porous rocks induced by seismic waves cause dissipation of wave field energy. The resulting seismic signature depends not only on the rock compressibility distribution, but also ...
An energy-based approach to estimate seismic attenuation due to wave-induced fluid flow in heterogeneous poroelastic media
(Wiley Blackwell Publishing, Inc, 2016-11)
Wave-induced fluid flow (WIFF) due to the presence of mesoscopic heterogeneities is considered as one of the main seismic attenuation mechanisms in the shallower parts of the Earth's crust. For this reason, several models ...
Wave attenuation in partially saturated porous rocks - New observations and interpretations across scales
(Society of Exploration Geophysicists, 2014-06)
Seismic waves propagating in porous rocks saturated with two immiscible fluids can be strongly attenuated. Predicting saturation effects on seismic responses requires a sound understanding of attenuation and velocity ...
Angular and Frequency-Dependent Wave Velocity and Attenuation in Fractured Porous Media
(Birkhauser Verlag Ag, 2013-11)
Wave-induced fluid flow generates a dominant attenuation mechanism in porous media. It consists of energy loss due to P-wave conversion to Biot (diffusive) modes at mesoscopic-scale inhomogeneities. Fractured poroelastic ...
