Description
Summary:The results of geochemical studies of four oils samples from Paleozoic deposits of the Labagan field of the Timan-Pechora oil and gas province are presented. It is shown that the organic matter, which generated the oil of the Lower Devonian and Tournaisian deposits of the Labagan field, is sapropelic, its accumulation occurred in a marine sub-reducing environment. The oils of the Artinskian and Ufimian deposits are substantially biodegraded. Type of collectors is fissure-porous, secondary-porous. Carbonate reservoirs of the Devonian, Carboniferous and Permian (Artinian) age are characterized by good and medium reservoir properties. Terrigenous reservoirs of the Ufimian deposit have good reservoir properties.
