Authors: A.P. Rozhkov (Gazpromneft-Noyabrskneftegaz OJSC), D.E. Zagranovskaya, A.S. Chinarov (Gazpromneft NTC LLC)

Features of the geological structure of pre-Jurassic formations of Sporyshevskaya area and sedimentary cover are given. Three seismic complexes are identified. Their characteristic is given. The ranking of wells of main fields in Western Siberia by the accumulated oil recovery is carried out. The prospectivity of development of marine Devonian-Lower Carbonian sediments of the barrier reef facies is established.
