| Shiranish Formation petroleum potential of the Euphrates basin (eastern Syria) | |
| The results of a comprehensive study of the Shiranish Formation in the Euphrates Basin in eastern Syria are presented. The Shiranish Formation is an Upper Cretaceous oil and gas source rock with significant potential for hydrocarbon generation and migration. Its widespread occurrence, significant thickness, and high total organic carbon content combined with a high degree of kerogen maturity make it a key element of the region's petroleum systems. In addition, it is considered an unconventional source of hydrocarbons. The study is based on a large amount of factual material, including the results of geological, geophysical, lithological, and geochemical researches. Data on geophysical well logging, microscopic description of thin sections, and geochemical parameters obtained using the Rock-Eval method are presented, on the basis of which a basin model of the studied region is constructed. To identify areas with the highest potential for free hydrocarbons in the Shiranish Formation, the volumes of oil remaining in the source rock were quantified. To solve this problem, a residual oil map was created - an important tool integrating various data and modelling methods. This map identifies the most promising areas with significant volumes of hydrocarbons, which serve as an important benchmark for targeted exploration and development of resources. Keywords: Upper Cretaceous oil and gas source rock, unconventional reservoir, Rock-Eval, well logging, basin modelling, Shiranish Formation, Euphrates basin, eastern Syria. |

| 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. |

| Statistical analysis of capacity filtration properties of the Yu3-4 reservoir units of Tyumen Formation (Uvat region) | |
| A detailed study of the Yu3-4 reservoir units is due to the significant prospects of their petroleum potential in the Uvat region, as well as the complexity of the petrographically structure, which leads to the problem of high variability of the filtration capacity of reservoir rocks. To solve it, reliable information is required on the composition and properties of the constituent rocks, which can be obtained by statistical analysis of the parameters of the core filtration capacity parameters. The structure and conditions of formation of the Yu3-4 reservoir units of the Tyumen Formation belonging to Uvat petroleum bearing region Western Siberia were studied. The main features of changes in the reservoir properties of the studied sequences are considered. An analysis of the relationship of the available data on capacity filtration properties was carried out, the main indicators of descriptive statistics were calculated and histograms of distribution by wells were constructed. Keywords: Tyumen Formation, Yu3-4 reservoir units, capacity filtration properties, Uvat petroleum bearing region, Western Siberia. |
