Geological and Geochemical History of the Formation of the Composition of Oil from the Pokur Formation of the Russkoye Oil Field in the West Siberian Oil and Gas Basin
摘要
Abstract
The composition and properties of oil from the Aptian–Cenomanian deposit of the Russkoye gas and oil field in the West Siberian oil and gas basin have been studied. It is shown that the composition and properties of the oil may indicate its mixed genesis. The molecular composition of the oil suggests that the oil has undergone secondary biodegradation processes, which is in good agreement with the geological history of this part of the basin. A scenario for the formation of the Aptian–Cenomanian oil deposit of the Russkoye field is proposed.
