| Patterns of geological structure and petroleum potential prospects of the Paleozoic carbonate strata of the Bolshe-Synia depression | |
| In order to identify spatial patterns of distribution of hydrocarbon generation centers and possible accumulations of oil and gas in the sedimentary cover of the Bolshe-Synia depression of the Pre-Ural regional trough (Timan-Pechora petroleum province), basin modeling of oil and gas formation and accumulation processes was carried out. The paper uses a structural model and an array of geological and geophysical characteristics of the basin, created as part of regional seismic surveys completed in 2022, and based on a comprehensive interpretation of the results of geological, geophysical and geochemical studies of the area. Basin modeling was used to reconstruct the change in the degree of catagenesis of organic matter and the realization of the potential for hydrocarbon generation by the parent strata during their subsidence movenment, which made it possible to make recommendations on the most promising areas of exploration for oil and gas in the Bolshe-Synia depression. Keywords: oil and gas potential, Paleozoic carbonate strata, basin modeling, Bolshe-Synia depression, Pre-Ural trough, Timan-Pechora petroleum province. |

| Oil and gas accumulation zones and the priority directions of renewal of oil reserves in the carbonate complexes, Varandey-Adzvinsky aulacogen | |
| On the basis of paleotectonic and thermobaric researches, prospective oil and gas accumulation zones are characterized, the revealed oil and gas accumulation zones are specified. They are estimated by the filtration-capacity properties of reservoir rocks, the initial production rates of wells, the types of reservoir rocks and traps. The priority directions of exploration works for oil and gas, their kinds and volumes in the Middle Ordovician-Lower Devonian and Upper Visean-Lower Permian oil-gas complexes within the onshore and Pechora Sea shelf of the Varandey-Adzvinsky aulacogen are substantiated.
Key words: Varandey-Adzvinsky aulacogen, Pechora Sea shelf, carbonate complexes, oil and gas accumulation zones, types of reservoir rocks, types of traps. |
