In northern West Siberia, a zone of petroleum accumulation has been identified, embracing the Nadym-Pur, Pur-Tazovskiy, Gydanovsk, and Yamal' petroliferous regions. A characteristic feature of this zone is the development of a thick (up to 2000 m) Cretaceous complex, with which the bulk of the gas and gas-condensate resources of West Siberia is associated. The origin of the gas-condensate deposits, discovered over a wide range from Upper Cretaceous (Cenomanian) to Jurassic, with differing hydrocarbon composition and amount of condensate, has been inadequately investigated, but nevertheless it has great significance in predicting the phase state of the hydrocarbons in the deposits and the reliability of estimating the reserves. The paper discusses the origin of these gas condensates from petroleum and coal deposits. 5 references.
