The article analyzes modern state of knowledge of the conditions of formation of oil and gas reservoirs in Miocene complex of the West Kuban trough. The conclusion about the irrelevance of theoretical representations of the formation of hydrocarbon deposits with the latest research in this area. Based on the above information, it is suggested that the formation of a specific individual accumulation must be genetically linked to the presence of an individual supply channel which is absent in other layers of the same traps. As such channels can be listric faults, which in the discharge of tangential stresses occurs injection of hydrocarbons.With the aim of increasing the reliability of the local forecast of oil and gas is proposed to use the integration of results of remote, hydrogeological, seismic and geochemical studies. The conclusion about high search potential of the Miocene complex West Kuban trough, indicating the most promising areas.
