At present a large number of fields in the Noybrsk region (West Siberian basin) are developed and characterized by decreasing of oil production. This fact often remains unexplored part of the section presented by the Achimov formation, which associated with the local areas of rapid sedimentation in submarine fans and associated channels. Local geological bodies in the Achimov formation can't be delineate without 3D seismic data. It is necessary to consider that local reservoirs are describes as the "thin layers". For their researching special algorithms are applied. The result of the study is a generalized regional map of the seismic anomalies which shows the presence of geological bodies (submarine fans and channels) inside the Achimov formation. The presented results were verified by drilling at several oil-fields in the Noyabrsk region, allowing it to be used for planning of exploration drilling of Achimov intervals. The scale of research is the main difference from previous investigations.
