East Siberia is one of the very promising areas for oil and gas explorations, but recovery and development of new deposits face essential troubles due to extremely complicated geological environment. For the first of all these troubles are connected with low self-descriptiveness of images computed with the help of regular migration procedures, both post- and prestack. In order to improve their quality and to increase resolving ability we propose and develop so called object-oriented technology of seismic processing. Its main advantage is ability to handle together reflected and scattered/diffracted waves both individually and in combination. This provides detailed knowledge of different features of the target geological objects – reflected waves describe their regular constituents (interfaces), while scattered/diffracted ones are responsible for fine properties like distribution of cracks/fractures/cavities.
