pdf The oil geology and geochemistry of Sorokin swell Permian and Carboniferous fields (Timan-Pechora petroleum province)
The results of geochemical studies concerning oils from Permian and Carboniferous fields of the Sorokin swell of the Varandey-Adzva structural zone of the Timan-Pechora petroleum province are presented. The reservoirs represented by carbonate of Carboniferous and Lower Permian age are characterized by good and medium reservoir properties - the type of reservoirs is mainly fractured- and secondary- pore. Based on our data, it was found that the oils were formed in the parent carbonate-clay strata with a significant contribution of algal source organic matter. It is likely that the Visean-age oil is generated by Silurian-Lower Devonian strata. The thermal maturity of the oils corresponds to the MK2 gradation of the transformation of the rocks organic matter.

Keywords: oil field, Paleozoic strata, reservoir properties, oil geochemistry, Varandey-Adzva structural zone, Timan-Pechora petroleum province.
