The triassic oil and gas complex is a potential object for the growth of the resource base of Western Siberia

The paper considers the results of analysis of information on the distribution of the Triassic deposits on the Western Siberia territory. It was established that the Triassic deposits are at different stages of catagenesis. Analysis of sediments distribution allowed defining that the highest potential for oil content is at the central and southern parts, and for gas at the northern area. It is assumed that the deep-seated Triassic deposits at the north of Western Siberia may be considered as a new potential gas-bearing object.
