Abstract
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.
Materials and methods
Theoretical – lithological-facies maps of the sakmarian deposits on the Tatarstan Republic. Practical – maps with the results of drilling bio-testing wells. Object of research – exploration areas on the territory of the eastern slope of the South Tatar arch.
Keywords
super-viscous oils, carbonate reservoir, sakmarian deposits, bio-testing wells, secondary mineralogy
