SUMMARY Seismic waves are typically assumed to propagate fast enough through a porous rock saturated with multiple fluid phases such that the interaction between the fluids can be considered adiabatic, or thermodynamically unrelaxed. However, at low

Seismic wave attenuation due to fluid pressure diffusion at the mesoscopic scale: an experimental and numerical study

Autor: Beatriz Quintal, Samuel Chapman, Jan V. M. Borgomano, Jérôme Fortin, Sally M. Benson

Monitoring of the subsurface with seismic methods can be improved by better understanding the attenuation of seismic waves due to fluid pressure diffusion (FPD). In porous rocks saturated with multiple fluid phases the attenuation of seismic waves by
