The modern theory of scattering allows quantifying the energy scattered off heterogeneities. Numerical modelling is the only way to investigate the scattered component. We explore wave propagation in media containing clusters of small scatterers using finite-difference modelling with local space-time grid refinement. With this method, snapshot images and synthetic seismograms of multi-offset reflections have been generated for a typical seismicgeological model of the Yurubchen-Tokhoma oilfield. Object-oriented migration applied to the synthetic data has allowed weighted superposition of images of the regular and singular objects. Thus, it becomes possible to use scattered energy as a new seismic attribute and to determine its relation with the concentration of small-scale voids in reservoirs.
