Geology and geochemistry of Riphean-Vendian petroleum system (the Northern part of the Volga-Ural Basin)

Abstract

Riphean-Vendian Petroleum system of Volga-Ural Basin (Northern part, Kama-Belsky aulakogen) main elements are described. Reservoirs and properties of them (porosity and permeability), source rocks are characterized geochemically by results of pyrolysis, extraction, gas chromatography. To understand the conditions of Volga-Ural Proterozoic petroleum system formation were analyzed lots of publications and collected huge dataset (regional geological data, seismic, well data, geochemical data and so on). Were made maps of Riphean-Vendian tectonics and location in North part of Volga-Ural Basin. The main characteristics important for petroleum system formation and oil and gas prospects estimation were indicated.
