The composition of biomarkers and aromatic hydrocarbons of Late Devonian oils of the Timan–Pechora Basin has been studied. It shows that the organic matter of oil-generating deposits is at the close stages of thermal maturity, which are within the early and middle stages of the oil window. Five groups of oils have been recognized, three of which were generated by organic matter of Domanik deposits and the other two formed from organic matter of another source. Most of the studied oil samples contain derivates of isorenieratene indicating that the organic matter of oil source rocks formed in the photic-zone anoxia of the paleobasin.
