Abstract

Summary

In this work, we numerically simulate seismic wave propagation in realistic fractured media to investigate characteristic scattering patterns. The linear slip model is used to describe the displacement discontinuity across the fracture. An integral approach, based on an element-level of discretization, is implemented to simulate elastic wave propagation. We used two typical incident angles, 0 and 90 degrees, to investigate their effects on scattering patterns, quantified by their scattering indices. The results show significant variations in wave scattering with different incident angles. More specifically, scattering indices are symmetric for both incident angles. However, the scattering index for the 90-degree incident angle displays a much more spatially distributed pattern than does the index for 0 degrees.
