The analysis of an actual material for the purpose of oil-and-gas content of oversalt and subsalt complex southwest part of Caspian Depression, according to results according to prospecting works. Features of distribution of oil and gas in nadsolevy and a subsalt complex were considered. This work was directed on formation of complex oil and gas geological model subsalt and oversalt complex to southwest part of Caspian Depression. The revealed regularities of oil-and-gas content indicate difficult nature of formation of oil and gas. Modern representations indicate incompleteness of formation of oil and gas. In the subsalt Paleozoic the variety of traps of the structural, lithology and combined types is predicted. Study of the subsalt Paleozoic of the considered region is characteristic now for a under search stage of researches (Western Kazakhstan, the Sarpinsky megadeflection, etc.) and an initial stage of search works (The Astrakhan carbonate massif, Karasalskaya bank and the Lobodinsky shaft). It causes big geological risk at rather low economic.
