Wave Propagation in Porous Elastoplastic Rocks: Implication for Seismic Attenuation.
We develop and study a 1D model for the acoustic wave propagation with two-phase physics and irreversible elastoplastic deformations in the rock matrix. We address the effect of the P-wave energy attenuation due to pore-scale plastic yielding in pre-stressed sedimentary rocks. The numerical examples are presented for drained rocks that capture major physical aspects of the process. We anticipate that our model can be used for monitoring of fluid flow in natural and artificial reservoirs using seismic data as well as it can be useful for earthquake engineering.
