Finite-difference modeling of 3D seismic wave propagation in high-contrast media

Preston, Leiph A.; Aldridge, David F.; Symons, Neill P.

Stable and accurate numerical modeling of seismic wave propagation in the vicinity of high-contrast interfaces is achieved with straightforward modifications to the conventional, rectangular-staggered-grid, finite-difference (FD) method. Improvements in material parameter averaging and spatial differencing of wavefield variables yield high-quality synthetic seismic data.
