Object of research - Miocene deposits of the Transcarpathian depression; subject of research – gas bearingness of Miocene deposits of the Transcarpathian depression; goal object: science-based prognosis of gas-bearing of Miocene deposits of the Transcarpathian depression; targets: classification, analysis and summing-up of new and interpretation of earlier geological and geophysical data, the selection of structural floors in profile of investigated area and characteristics of space-age relations and structural correlation between them, reconstruction of conditions and stages of neogenic sediment in Transcarpathian paleobasin, description of facies types of Miocene strata, determine their distribution, the selection of gas-bearing complexes included in Neogene formation of Transcarpathian depression with strata describing, which have the properties of reservoir rocks and fluidlimit stop, the selection of objects to search for gas in the Transcarpathian depression on the basis of complex analysis of criteria for prediction of hydrocarbon deposits, making of map of thickness and grittiness of gas-bearing complexes of complexes Neogene deposits of depression, construction of structural maps of pre-Neogene base of depression, creating maps of prognosis of gas-bearing of Miocene deposits of the Transcarpathian depression, to identify the most perspective (with a view to gas deposits searching) area;. methods: structural-tectonic, lithologic-facies, paleostructural, the method of comparative analogy, complexing, analysis and systematization of geological and geophysical information, literature processing. The practical significance of the results. Presented research work will contribute to separation areas, perspective to identify local structures in which to expect the opening of small (up to 10 billion m3 of gas) and medium (10 to 100 billion m3) gas deposits. In case of shallow deposits and the relatively small cost for their development, they could provide hydrocarbons to local objects - some towns, districts or region. Scientific novelty of the results: Rupel-Eherskyi and Carpathian Grushiv and Tereshulsk Suites gas perspective complexes have been marked in Miocene deposits of the Transcarpathian depression, maps of thicknesses and grittiness of deposits of Grushiv and Tereshulsk Suites have been done for the first time; specified limit of distribution of Badenian, Sarmatian and Pont-panonskyh formations of Neogene deposits of Transcarpathian depression have been defined; the main criteria of gas bearingness of Neogene sediments have been described; new directions for geological exploration and brilling search within depression have been proposed, the map of gas bearing perspectives of Miocene deposits of the Transcarpathian depression has been done and the most perspective areas for gas searching have been outlined; spheres of using: geology of oil and gas.
