Middle-Devonian oil and gas reservoirs in the south of the Buzuluk depression: Their structural peculiarities, depositional environments, and oil-and-gas potential

The greater part of the total initial resources of the Buzuluk depression are located in the MiddleDevonian complex in the southern area. An integrated analysis of the results of macro- and microscopic core studies along with the interpretation of seismic and well-logging data resulted in the development of depositional reservoir models for Middle-Devonian sediments. The models allow one to predict the occurrence of natural reservoirs that are capable of containing oil and gas accumulations.
