Abstract

Accurate numerical modeling tools are of practical importance for understanding of seismic wave propagation in reservoir rocks. 2D finite-difference (FD) poroelastic code is used for simulation of acoustic wave propagation through water saturated medium with regular distributed circular gas inclusions. The results of the numerical simulations are validated with the newly derived theoretical solution for the same geometry of patches. Finally, the numerical results for a media with randomly distributed patches are used to verify the interpretation of the results of a laboratory experiment in which saturation and compressional velocity are simultaneously measured in a sandstone sample.
