We consider the formation history of high-amplitude anticlinal trap structures for unique Cenomanian gas pools using the example of the Medvezh'e field. Analysis shows that the Turonian-Cenozoic was the most crucial stage of formation of the world's largest gas-bearing province in northern West Siberia. This stage was marked by (1) the formation of large anticlinal traps-petroleum-promising objects; (2) the highest intensity of gas formation, which caused the filling of these traps; and (3) the formation of the Kuznetsov seal, which shields the giant Cenomanian gas pools
