A massive seismic database, which includes 1000km of CDP profiles, well logs and deep drilling, from 30 boreholes and the Ostaninskoye and North Ostaninskoye fields located in the southeast of West Siberia was analyzed in this paper. The analysis allows a conclusion that the Callovian-Kimmeridgian section within study area has a stratified structure and the productive sandy beds, being commonly identified as a single bed Yu13-4 , are non-isochronous within the Ostaninskoye and North Ostaninskoye fields and may thus constitute independent oil and gas traps.
