Improved methods of identifying promising local objects in old oil and gas areas (on the example of the West Kuban trough)

The article analyzes the modern state of knowledge of the conditions of formation of oil and gas reservoirs in the West Kuban Trough. It is necessary to recognize the discrepancy between the theoretical concepts of the generation of hydrocarbon deposits and the results obtained in this area. On the basis of the above information, it is suggested that the formation of a specific accumulation of HC should be influenced by such factors as an individual lead channel, which is absent in other layers of the same trap. As such channels, listric faults can occur, in which an injection of hydrocarbons occurs during the discharge of tangential stresses. With the purpose of improving the methodology for identifying promising local sites in old oil and gas bearing areas, it is proposed to carry out complex studies by remote, hydrogeological, seismic and geochemical methods. A conclusion is drawn on the high search potential of the Miocene complex of the West Kuban Trough with the indication of the most promising areas
