As a rule all oil fields in East Siberia are confined to local heterogeneous lithologic substitution. These areas usually possess higher level of fracturing and besides of reflected waves generate scattered ones with rather high amplitude. Both regularly reflected and diffracted/scattered waves should be used in order to get the proper seismic image of reservoirs structure: reflected waves fix its position while scattered waves are responsible for its internal structure. So, one needs in adaptable seismic imaging procedure to describe the reservoir. This procedure should be able to be tuned to image either regular interface or, vice versa, to destroy their image in order to be focused on imaging of scattering object. Below we present such procedure on the base of Focusing Transformations.
