|Geophysical and lithological-geochemical requirements of oil and gas industry of the deep and shelf basins of the Russian Eastern Arctic|
|In the Aptian-Cenozoic study of each of the sedimentary basins in the eastern Arctic, five identically dated seismic-stratigraphic complexes have been identified reflecting the relationship of the rift systems of the eastern Arctic shelves and the deep-water basins of the Central Arctic region. Lithological composition and thickness of deposits, types and thermal maturity of organic matter were reconstructed. The reconstruction is based on data from seismic profiling, underwater drilling, and study of bottom sediment samples, seismic velocity analysis and assessment of oil and gas prospects of the neighboring Arctic shelf.
At the present stage, generation and accumulation capabilities are characteristic mainly of the Upper Cretaceous and Cenozoic fluidodynamic systems of the sedimentary cover. The Paleozoic-Mesozoic rocks of the acoustic basement (in the absence of catagenetic unconformity at its boundary) serve as a secondary source of hydrocarbons entering the fractures of the fault zones into the sedimentary cover of the basins. The shelf North Chukchi and the shelf-slope of the Fore-Eastern Siberian basins are the most promising in the oil and gas bearing respect, the productivity of which is predicted in a wide range, basins which also extends to great depths.
Large oil and gas and gas accumulations can be discovered on the slopes and horst elevations of the basins. The relatively shallow occurrence of Lower Mesozoic and Upper Paleozoic formations on the southern slope of the North Chukchi Basin makes this region particularly attractive as oil and gas prospect. In the deep-water basins belonging to the high-latitude Arctic, potentially oil-and-gas bearing targets are assumed in areas adjacent to the major basement uplifts, which separates the large basins from the small basins of the foot of the slopes of the Lomonosov and Mendeleev Ridges.
Keywords: seismostratigraphic sections, oil and gas reservoirs, catagenetic maturity of organic matter, fluid dynamic systems, centre of oil and gas formation, potentially oil and gas bearing targets, Russian Eastern Arctic.

|Forecast of petroleum potential of Laptev Sea shelf|
|The features of structure and petroleum potential of Laptev Sea shelf are analyzed. The forecast of age and lithological composition of the sedimentary cover is presented, oil and gas source strata, catagenetic zoning of organic matter and promising oil and gas objects of major structural zones are characterized. Except gas, a prominent role of oil is assumed as part of hydrocarbons. Oil generation in the coastal part is caused by the presence of high-quality oil source strata of the Riphean-Phanerozoic cover extending to the shelf of the Siberian craton. Oil and oil-gas deposits can also be present at the rest of the shelf, as in rift Cenozoic sediments are assumed not only gas source but also oil-and-gas source strata of deltaic and avant-deltaic origin, located in the main oil generation zone.
Keywords: shelf structure, sedimentary complexes, oil and gas source strata, katagenesis of organic matter, oil and gas potential, Laptev Sea shelf.

|Petroleum basins of the South Atlantic: development stages, structure and hydrocarbon potential|
|Sedimentary basins of the continental margins of the central part of West Africa and Southeast Brazil formed by the common scenario on the background of the disclosure of the southern segment of the Atlantic Ocean. The similarity of basins represented in structural styles, composition of lithologic and stratigraphic filling, high quality of petroleum source strata, biomarker composition of oils, similar stratigraphic range of petroleum potential horizon and hydrocarbon resources. The differences related to local features of halo-kinesis, different time of progradations and erosions, especially active during final stage of basins development. At the same time many Mesozoic structures and faults reactivated, the number of anticlinal traps increased, the conditions of oil and gas formation and accumulation, which also covered the continental slope, improved significantly.
Keywords: structural style, petroleum potential horizon, petroleum source strata, biomarker composition of oils, halo-kinesis, progradation, South Atlantic.
