The object of our research is the Tyumen formation of the West Siberian basin. Near 300 core samples were studied by a complex of lithological and organic petrology methods to reconstruct the depositional environments. Three types of different hydrodynamic regimes have been recognized for the Tyumen lithofacies accumulation. Studies of organic matter have shown that the Tyumen formation is not so much oil-bearing, and it may be promising for generation of gas from coal and coal rocks, and to a lesser extent of oil. Such new reservoirs can be identified within the alluvial and shallow marine
