Accurate Modeling of Fractured Reservoir Not Using Equivalent Medium Theory

The presence of heterogeneities (like fractures) in a reservoir can be analysed by the mean of equivalent medium and anisotropy but also with the scattered energy generated. In this paper we show that this scattered energy is quite important on a large scale model were the upscaling used for fracture description is very limited (grid cell size is .5m). Finite Differences (based on a new scheme) and Born Modelling have been used to produce synthetic seismograms.
