Numerical Simulation of Seismic Wave Propagation in Attenuative and Heterogeneous Media

Bernard Adero

Abstract: In this study, we present a forward numerical simulation approach to investigate seismic wave propagation in attenuative and heterogeneous geological media. Using a finite difference method to solve two-dimensional viscoelastic wave equations, the research evaluates the effects of attenuation on wave amplitude and dispersion. By comparing lossy and non-lossy models, the study highlights how attenuation alters seismic waveforms and how compensation techniques can restore energy loss. Numerical tests in both homogeneous and heterogeneous media, including a modified Barnett Shale model, demonstrate the model's ability to replicate realistic seismic scenarios. This suggests that the proposed approach is a valuable tool for improving seismic interpretation, particularly in contexts where wave attenuation complicates imaging processes.
