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.

pdf Organic matter formation conditions and content of the Lower Carboniferous strata in the north of the Timan-Pechora petroleum province
We analyzed the thickness and petroleum bearing properties of Tournaisian-Visean strata in the north of the Kolva megaswell in the Timan-Pechora petroleum province. Geochemical studies of the organic matter allowed clarifying its type of organic composition composition and its degree of thermal maturity.
We determined that the initial organic matter had been accumulated under similar marine and coastal-marine conditions and consequently organic matter composition was somewhat different. By now, the degree of thermal organic matter transformation corresponds to the beginning of the "oil window" phase, which suggests presente the formation of oil accumulation in this section.

Keywords: organic matter, "oil window", Tournaisian-Visean, petroleum bearing properties, Timan-Pechora petroleum province.

pdf Geochemical characteristics of Gamburtsev shaft oils
The composition of cyclic and acyclic hydrocarbon biomarkers, aromatic hydrocarbons and dibenzothiophenes of the oils of the Gamburtsev shaft was investigated. The hydrocarbon composition of the oils of the three studied fields – Cherpayu, Khasyrey and Nyadeyu is almost identical; these oils share a common source of organic matter. Based on the complex of the obtained data, it was found that the oils were produced by carbonate-clay source rocks with a significant contribution of the algal initial organic matter. It is likely that the oils are syngenetic to the host Silurian-Lower Devonian. The thermal maturity of the oils corresponds to the oil window peak.

Keywords: Silurian - Lower Devonian, oil biomarkers, aromatic hydrocarbons, oil dibenzothiophenes, Gamburtsev shaft.

pdf  Silurian and Lower Devonian petroleum source rocks of the Chernov Ridge (Timan-Pechora Basin, Russia)
The article presents the results of geochemical research of Silurian and Lower Devonian sequences on the Chernov ridge. The main part of the section is represented by petroleum source rocks with (TOC concentrations of 0,1–0,5%). Petroleum source rocks with increased contents of organic matter (> 0,5%) belong to clay-carbonate intervals in Silurian part of the section and layers of bituminous dolomites in the Lower Devonian. The hydrocarbon composition of the saturated fraction of bitumen in the Silurian-Lower Devonian deposits show a sapropel organic matter, probably of a different genetic types – plankton and marin algae. The isotopic composition of organic carbon (?13С, ‰) of bitumen part (30,1–32,6‰) and kerogen component (30,9–31,1‰) confirms the sapropel genesis of organic matter. The level of catagenetic transformation, estimated by the conodont colour alteration index, indicates that the Silurian-Lower Devonian deposits are in the main zone of oil generation (subdivision of the catagenesis MK1-2). The process of hydrocarbon generation is confirmed by the presence of bitumen throughout the section of the Silurian and Lower Devonian sequences.

Keywords: Silurian and Lower Devonian sequences, source rock, organic matter, bitumen, isotopic composition of organic carbon, Chernov ridge, Timan-Pechora Basin.

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.

pdf Voysk solid bitumen field
We presented the results of detailed lithological and geochemical researches of the Voysk solid bitumen field of the Timan-Pechora Province, localized in Lower Visean sandstones of deltaic genesis. We considered the bitumens to the class of asphaltites by their elemental and group composition. By the methods of gas chromatography and chromato-mass spectrometry we confirmed that the bitumens had undergone intensive bacterial degradation. We studied the isotopic composition of carbon of both the bitumens and their individual fractions.

Keywords: natural bitumen, hydrocarbons-biomarkers, Lower Visean, carbon isotopy, Voysk bitumen field, Timan-Pechora Province.

pdf  Composition and organic matter character of mudstones in the Lower Carboniferous of the Pechora basin
Lower Carboniferous terrigenous rocks include sandstones and aleurolite-argillaceous rocks transformed to different stages of katagenesis. We studied the sections from the outcrops in the Subpolar and Northern Urals, as well as from the wells of the Pre-Urals Foredeep. We revealed similarities and differences in mineral composition of the argillites and related organic matter, which is a very important observation concerning the prospective evaluation for further petroleum exploration in the Timan-Pechora Province.

Keywords: organic matter, mudstone, clastic sediments, post-sedimentation change, reservoir properties, Subpolar and Northern Urals, the Timan-Pechora petroleum Province.
