The authors analyze the Kashirskian carbonate sediments in the Kuakbashskaya area in terms of their oil potential. The paper discusses the reservoir properties of the Kashirskian carbonate sediments, results of well-logging re-interpretation, correlation between well logging and field surveys data. Challenges related to defining of reservoir-beds and their saturation with formation fluids are highlighted. The complexity of the Kashirskian cross-section implies its further detailed study to discover hydrocarbon accumulations.
