Study of mapping features of preconditions for formation of hydrocarbon deposits on the continental slope of the Western Black Sea basin

The integral thermo-atmogeochemical structural investigations (TAGSI) have been carried out at the continental slope of Western Black Sea Depression for first time. technique TAGSI as non-traditional and cost-effective exploration technology is originally developed Institute Geological Sciences. It consists phased geo-structural researches analysis fault tectonics, morphological neotectonic interpretation space images, thermal atmo-geochemical surveying, lab measurements processing data acquired to build thematic map using GIS technologies. Field acquisition stage includes thermometric, emanation gas surveying (Rn/Tn, He, CO2, H2, free hydrocarbons) in petroleum-prone onshore areas bottom sediments (up 2 m below surface) thermometry, Rn-metering content near-bottom layer offshore.To conduct there was a special instrument with some modifications designed work offshore respectively. This tested different regions Ukraine over known oil fields. results are considered paper. geostructural analysis, atmogeochemical survey near-­bottom water (radon, helium, carbon dioxide, hydrogen, hydrocarbons), thermic lithogeochemical examination enable outline petroleum-promising areas. Morphological, structural, tectonic, stratigraphic features slope’s structure characterized. has found that potential petroleum-bearing structures occur region, which genetically similar productive Mesozoic Cenozoic stratons northwestern shelf other Crimean – Caucasian Region. studies show it purposeful use local forecast promising targets early search stages, rational location drillholes, prospecting recovery hydrocarbons.
