pdf Petroleum geology and geochemistry of Labagan oil field (Timan-Pechora Petroleum Province)
The results of geochemical investigations of the Tournaisian and Artinskian sequences of the Labagan oil field (Timan-Pechora Petroleum Province) are presented. The reservoirs are represented by carbonate rocks of Carboniferous and Permian age, are characterized by good average reservoir properties; the type of reservoirs is crack-pore and second-pore. The oil from the Tournaisian Labagan oil field was generated by sapropelic organic matter, the accumulation of which took place in marine restrictive conditions. The oil of the Artinskian sections has been substantially biodegraded and the reconstruction of their genesis requires additional research.

Keywords: Carboniferous rocks, Lower Permian sequences, n-alkanes, isoprenoids, Labagan oil field, Timan-Pechora Petroleum Province.
