Application of the sequence-stratigraphy method has allowed to trace the principal stages in development of the Middle Ordovician – Silurian sedimentation within the Pechora-Barents sedimentary megabasin. There were established, on this base, some regularities in distribution of reservoirs and seals in the geologic section of the Low-Middle Paleozoic.
Sequence stratigraphic method allowed us to divide the Middle Ordovician-Lower Devonian oil-and-gas bearing complex of the Timan-Pechora province into 10 sedimentary sequences of 3rd order, lasting from 4 to 10 million years. The lithofacial zones location predicted on the basis of the sequential stratigraphic method and analysis of their reservoir potential allows us to determine the distribution patterns of reservoir, screen and oil-bearing strata in the section and perform their mapping. Application of the given technique has allowed to allocate the area with probable concentration of hydrocarbon raw materials in the organogenic structures of the middle Ordovician and lower Devonian in the Timan-Pechoro-Barents Sea paleobasin. The uniqueness of the development is related to the prediction of zones with reservoir properties on the Arctic shelf of Russia, where giant deposits of oil, gas and gas condensate have been discovered, which allows us to model the process of trap formation and limit the exploration areas in the near future on the northern borders of the country.
