Formation of Oil and Gas Reservoirs in the Great Depths of the South Caspian Depression

The aim of this article is the identification and characterization of complex factors acting simultaneously on forming large sized reservoirs in the deep South Caspian Basin, as well as the development of a model based on a combination of synchronous natural processes of the formation of hydrocarbon deposits. The article analyses reasons for high layer pressures in the hydrocarbon fields of the South Caspian Depression (SCD), impacting factors. The tectonic factor and density-barometric model can become the main criterion for selection of priority projects for exploration and site selection for drilling wells. Obtained results allow conducting effective studies of the exploration and development of oil and gas condensate fields in the SCD area.
