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.
