P003 Micro-scale Modeling of Poroelastic Reflection – Theory vs Numerical Simulation R. Ciz* (Freie Universitaet Berlin) E.H. Saenger (ETH and Spectraseis Zurich) & B. Gurevich (Curtin University and CSIRO Petroleum Perth) SUMMARY Numerical rock physics is an emerging tool in the analysis of elastic wave propagation on micro-scale. The viscoelastic extension of the displacement-stress rotated staggered finite-difference (VRSG FD) grid technique is applied to the numerical modeling of poroelastic phenomena. Specifically the simulations of the reflection from the poroelastic interface are performed on micro-scale. The effect of the Biot’s slow wave on the reflected fast compressional wave is investigated in
