Geological development of the region caused forming of mineral deposits, characteristic of platform areas. oil, gas, condensate determining the social and economic development of the region are among the most important its minerals. Now in the region more than ten fields of UV are revealed, part of them is in development. The revealed fields lie in a wide interval of depth (700-4100 m) within various structural and tectonic zones. There are favorable prerequisites of opening of new fields in various areas and complexes. The main prospects of oil-and-gas content both the most large-scale and largest deposits are dated for subsalt Paleozoic (coal) deposits. They lie down at big depths and are in tough the termobaric conditions. Their searches and investigations are connected with great difficulties and material costs. As the main object local structures for which practically all identifications of fields of UV and oil and gas manifestation in a nadsolevy complex are dated are considered. Typification of salt structures (traps) depending on their provision on the morphostructural elements of salt structures is added. The most perspective structural traps in regions of absence salt tectogeneses are determined. The allocated sites of carrying out the search reconnoitered works in various regions of the considered territory.
