P327 Simulation of Wave Propagation in Poroelastic Structures Using a Modified Finite-Difference Scheme F. Krzikalla (University of Karlsruhe) & T.M. Mueller* (University of Karlsruhe) SUMMARY Hydrocarbon reservoir rocks are composite materials with gas or liquid phases filling the pore space between the solid grains. A neat understanding of wave propagation within such structures is important for the interpretation of seismic surveys in petroleum exploration. In this paper we present a velocity-stress finite-differences (FD) scheme to simulate waves within poroelastic media. The mathematical background is provided by Biot’s theory of between particle motion stress and pore pressure by means of two
