Abstract
The mapped heights of gas in traps and depths of occurrence of the traps in the northern and arctic regions of West Siberia have been analyzed. On the basis of this analysis, conclusions were made about the main factors controlling the formation and localization of the giant Urengoi-Yamburg gas-bearing zone. A similar anomalous gas-bearing zone with largest reserves in the Cenomanian deposits is predicted to exist in the Kara Sea (the south-southwestern Yamal oil- and gas-bearing area).
