The 3.5 million sq. kilometers Western Siberian basin is one of the world's important petroleum producing provinces, contributing approximately 10% of the world's hydrocarbon production. The Mesozoic/Cenozoic basin-fill consists of continental and marine clastic sequences that have an aggregate thickness of 1.5 km to over 12 km. The basin-fill complex overlies a mosaic of Paleozoic and Precambrian sedimentary, metamorphic, and igneous rocks which were consolidated during the late Paleozoic.

The hydrocarbon resources of the West Siberian petroleum province rank second in the world to those of the Arabian Gulf petroleum province. Several of the gas and gas/condensate fields of West Siberia are in the "super-giant" class and are ranked in the "Top Ten" of the world's largest accumulations. Numerous oil accumulations in the basin can be classified as "giant" oil fields.

The hydrocarbon resources of West Siberia are contained in over 2000 separate pools that occur in over 350 oil/gas fields. The pools occur in clastic and carbonate rocks of Paleozoic, Jurassic, and Cretaceous age. The distribution of these hydrocarbon resources in time and space will be illustrated.
