P188 FD MODELLING OF VISCOELASTIC WAVES IN MEDIA WITH ORTHOROMBIC ANISOTROPY B. O. RUUD and S. HESTHOLM Centre for Integrated Petroleum Research University of Bergen Allégt. 41 N-5007 Bergen Norway Summary 1 Fractures in rocks can lead to considerable anisotropy in effective medium properties. Fluid flow induced by elastic waves in fractured rocks can also lead to high seismic attenuation. As a means for seismic modelling in such media we have extended existing isotropic viscoelastic finite difference (FD) methods to orthorombic media. The relevant theory is summarized and results for an explosion source in a simple two layer model are
