The present work is devoted to consideration of the geological structure and petroleum potential of Promyslova-Poldnevskiy area of the Caspian basin. The article provides a brief historical background on geological prospecting, geophysical surveys and drilling carried out in this area. Topics tectonic evolution and petroleum potential is considered in more detail as they are the most important aspects of the search and exploration deposits of hydrocarbons. The charts and maps of the study area can visually assess these aspects. Based on the available data within the shaft Karpinski allocated smaller tectonic elements, resulting disjunctive and plicative movements. The research territory is located within one system, in the Jurassic sediments within the Caspian and North Caucasus Mangyshlak provinces. In the Jurassic sediments are productive sandy-silt sediments Bajocian and aalenskij ages. Briefly described lithologic-stratigraphic structure of the major oil and gas complexes. When active deployment exploration in prospective areas (field geophysical, geotechnical, environmental surveys, and exploratory drilling) required an in-depth summary of the results of the operations, and the creation of geological linking them with previously performed studies on sea and adjoining land for the purpose of scientific study and further effective placement of the geological works.
