Abstract
Reconstructions of paleo-sedimentary environments in the North-Eastern Black Sea were intended to achieve three main objectives: to forecast the geographical range and depositional environments of potential oil/gas source rocks, reservoirs, and seals; to study sedimentation environments in the areas of fields - analogs for the purpose of quantitative assessment of prospective targets’ potential in the Black Sea Basin, to prepare a necessary part of input data for three-dimensional basin modeling and prediction of oil and gas occurrence offshore. The research results indicate that, reasoning from sedimentation environments, Middle Jurassic, Lower and Upper Cretaceous, and Maikopian clayish deposits accumulated in the deep-water environments of the outer shelf and continental slopes of age-appropriate paleobasins, may have oil and gas source rock properties. Reservoirs may be represented by Upper Jurassic shelf carbonate deposits, Lower Cretaceous clayish carbonate deposits, Upper Cretaceous carbonate deposits, Maikopian and Middle-Upper Miocene coastal or deep-water ( turbidite ) terrigenous deposits. Terrigenous and terrigenous-carbonate deposits of different horizons in the sedimentary section may serve as cap rocks.
