Forecast oil content of sakmarian sediments in the east side of Tatarstan Republic according to study core matherial of bio-testing wells
The trend of annually increasing oil production in the Volga-Ural oil and gas province requires increasing the mineral resource base by opening new fields or entering into development of hard-to-recover (unconventional) hydrocarbon reserves. One of this alternative sources of hydrocarbons is Permian bitumen, which is concentrated in the ufimian, kazanian and lower permian sediments in the south-east of Tatarstan. Prospects for the discovery of small bituminous deposits are also available in the eastern part of Tatarstan, where positive forecasts for hydrocarbon raw materials for the deposits were obtained according to lithological, tectonic criteria and the results of drilling test wells.
