Association of oil-hydrogen and salt accumulation from the position of the technology of structural-thermo-atmo-geological-geochemical studies
Abstract
The logistics of structural-thermo-atmo-geological-geochemical technology is justified, which consists of a comprehensive approach to substantiating the regularities of spatial-temporal functioning of oil-salt fluid transport systems, creating geological fluid dynamic models, optimizing the search for oil, gas, and hydrogen deposits, gas hydrates at both shallow and significant depths, using a systematic methodology for building stratigraphic models and diagrams. The system of geological methods has been analyzed: litho-biostratigraphic, paleosedimentological, tectonic, morphostructural, geodynamic, geophysical, seismic, and others. A complex of thermoatmo-geochemical studies has been applied to determine the criteria for predictive mapping of promising areas and assess the prospects for hydrocarbons. Oil-salt nodes with giant oil and gas potential and salinity of sedimentary basins on Earth have been analyzed. Using the STAGGD methodology, the spatial-temporal distribution of oil and gas formations in the junction zone of the East European platform and the Tethyan riftogenic belt, Western (Carpathians), Southern (Forecarpathians, Black Sea, Crimea, Azov-Black Sea basin), and Eastern (Dnieper-Donets depression) oil and gas regions of Ukraine has been characterized. Detailed analysis of the regularities of spatial-temporal distribution of terrigenous-carbonate, terrigenous-clayey, terrigenous-limestone formations, salt dome structures, conditions for diapir formation in Phanerozoic cyclical oil-salt formation complexes has been carried out using lithological stratigraphic, geophysical, seismic, atmospheric, thermal, geochemical methods. Special attention has been paid to a detailed analysis of the geological structure and conditions of oil-salt accumulation in the Carpathian oil-gas-salt region as one of the largest oil-salt nodes of the Earth's riftogenic belt. Information on the placement of potential underground hydrogen storage within salt formations is provided.
