Connection between geotectonic zoning of the territory and its oil and gas potential is shown on example of the actual drilling data of Dnieper-Donets Rift. First of all, the zones of connection of different geotectonic elements are the most promising, which is confirmed by their modern geodynamic activity. In this article, such transition zones are called seam rift zones (SRZ) for combining compression (seam) and stretching (rift) conditions. SRZs are distinguished by a wide range of aerospace, morphometric, geological and geophysical data.

Modern integrated interpretation of borehole and seismic data allows solving a wide range of problems based on the construction of reliable conceptual geological models of the studied areas. The total correlation of seismic horizons allows us to consider the studied section in all its details with the maximum use of seismic information and to ensure its objective comparison with well data. This approach is especially important for the purposeful study of the prospects for oil and gas potential, both in structural traps and non-structural traps, on the one hand, and the construction of objective geostatic models, on the other

The Transcarpathian foredeep of Ukraine is a geological unit within the Carpathian folded structure, presented by Neogene molasses, which cover Pre-Neogene folded base. Five deposits of combustible gas were discovered within the foredeep – Russko-Komarivske, Stanivske and Korolevskoye within the Mukachevo depression and Solotvino and Dibrovske fields within the Solotvino depression. Despite the fact that most domestic researchers adhere to the view of gas migration along deep tectonic faults into the sedimentary cover of the Transcarpathian foredeep, it is important to analyze the basin for favourable conditions for the generation of natural gases within the sedimentary cover. Samples of core material, selected from 57 intervals of different age complexes of rocks from Transcarpathian wells for quantitative estimation of total organic carbon in rock, were analyzed in the department of sedimentary strata of IGGCM NASU. The results of the studies indicate the presence of rocks with low as well as good and even very good oil and gas potential for total organic carbon content, which are overwhelmingly related to the deposits of Pre-Neogene folded base. In general, a wide range of TOC content is established by the analysis. Rocks with TOC content of more than 1% are found both in rocks of the Pre-Neogene base (w. № 22-, 23-Solotvino, 1-Bushtinska, 1-Borodivsko-Novosilska), and in the molar thickness of the Neogene (St. No. 1-Velyko-Dobronska, 8-Tyachivska), which indicates sufficient content to generate hydrocarbons. Further research aimed at determining the oil and gas potential will allow to determine the priority directions of oil and gas exploration within the Transcarpathian foredeep.

Complex interpretation of seismic and parametric drilling data is performed. The data for interpretation are obtained within the conjunction zone of the Kureyka syncline and the Anabar anteclise. As a result of complex interpretation the structural maps on the bottom of Vendian and the top of the Kuonamka formation are constructed. Map of the Vendian terrigenous complex was constructed. High prospects of oil and gas potential of the lower-middle Cambrian sediments are shown. Based on the analysis of logging data, core description and detailed correlation of time sections, the litho-acoustic models were compiled for two profiles crossing the barrier-reef system, and two-dimensional synthetic time sections were calculated. Obtained results confirm the correctness of the ideas about the internal structure of the Vendian-Cambrian complexes.

Research subject. The Yamal Peninsula is of interest due to the fact that the concentration of hydrocarbon deposits per unit area is more than 100 times higher than the “world average”, which is confirmed by the reserves of the largest oil and gas fields already discovered. At the same time, the knowledge of the deep horizons of the earth’s crust and mantle within the Yamal and adjacent areas is clearly insufficient in comparison with more southern regions.Methods. In this work, the method of seismic tomography was used, which makes it possible to identify anomalies in the velocities of seismic waves directly related to the heat flow density and geodynamic activity of the subsurface.Conclusons. Apparently, the Western Yamal positive thermal anomaly indicates a region of a high geodynamic activity permeable for deep fluid-gas streams. The location of Yamal on a slightly raised shoulder of this anomalous region has determined the high oil and gas potential of this peninsula. Other regions situated in the vicinity of the discovered thermal anomaly may present significant research interest.
