Cambrian barrier reef systems of Siberian platform: petroleum potential in light of new geological and geophysical data

The authors discuss exploration history, geological features, and factors of oil and gas occurrence in the Cambrian barrier reef systems of the Siberian Platform. Basing on geological exploration results of recent years, geological structure of reef systems and adjacent facies zones is updated, the expected types of hydrocarbon traps are identified, and delineated oil and gas resources are assessed. The conclusion is drawn that geological exploration should continue, including the need for stratigraphic drilling both within the barrier reef system and within the basin part of the section
