Semeniuk V. Determination of prospecting features of oil and gas content of the Boltysh Impact Structure according to geological-structural and thermo-atmo-hydrological-geochemical data.

The dissertation is on the determination of the prospecting features of oil and gas content in impact structures according to geological-structural and thermo-atmo-hydrological-geochemical data on the example of the Boltysh Impact Structure. The paper deals with the peculiarities of the distribution of gas in the underground air, the influence of tectonic disturbances and fracture zones over the impact structure on oil and gas content is determined. In the course of the dissertation work, the results of research and production works on the study of the geological structure and the estimation of oil and gas content of the Boltysh Impact Structure were analyzed, which made it possible to estimate the volume of work done and allowed to select the objects of research scientifically and to predict the oil and gas content of the research area by the complex of structural-thermo-atmo-hydrological-geochemical studies (STAHGS). During the research, patterns were identified in the manifestation of ring structure and search signs of oil and gas potential. Of particular note is the analysis of the distribution of geological-structural and thermo-atmospheric-hydrological-geochemical parameters within the ring structure. For the first time, forecasting and exploratory signs of oil and gas potential were identified for the STAHGS complex of the Boltysh Structure. Based on the research results, recommendations are given for the use of geological-structural and thermo-atmospheric-hydrological-geochemical data to determine areas prospective for hydrocarbon production. Key words: astrobleme, impact structure, hydrocarbons, zones of high permeability, prospecting shows of oil and gas content of crystalline basement, structural-neotectonic interpretation, atmogeochemical indicators, emanational, gasometric, hydrological and hydrogeological surveys.
