Abstract

Summary

We present a numerical study of seismic wave propagation in fluid-filled fractured-porous media. We consider models of fractured media with two typical scales. The first one is the scale of a single fracture, the second one is the scale of the percolating fracture clusters. We generated the models with different percolation length, suggested and approach to characterize the geometrical properties of the clusters and then performed simulation of seismic wave propagation. According to the results of the simulation, we observe strong dependence of seismic attenuation on the length of the percolating clusters due to both the fracture-to-background wave-induced fluid flows and due to the scattering. Whereas fracture-to-fracture flows are not distinguishable at acoustic frequency band.
