The review of researches about the influence of paleoclimate (a century level temperatures chart on the surface of the Earth) on thermal history of deep source rocks and its influance of its generation potential is provided. Influence of the Mesozoic-Cenozoic climate on a geothermal regime of the Bazhenov Formation source rocks of south-east Western Siberia (Novosibirsk region) is estimated. The paleoclimate assessment on the basis of paleotemperature modeling verification results and identification by geotemperature criterion of paleospot of the Bazhenov oil generation in sedimentary sections of three deep wells which have been drilled in Bazhenov Formation on the Verkh-Tarsk area is carried out. The reconstruction of the thermal history of source rocks excluding paleoclimate won't be coordinated with "maximum paleotermometry" - vitrinite reflectance data and construct petroleum potential section. The local century course is recommended to be considered when determining of hydrocarbon resources by a volume and genetic method of the Tomsk, Novosibirsk and Omsk areas. Local century level temperatures chart of Earth's temperatures of the terrestrial surface, used at construction and reconstruction for the Southern Siberian paleoclimate zone, significantly contribute to ameliorate the oil resources prognose.

Keywords: paleoclimate, paleotemperature modeling, source rock, Bazhenov Formation, inferred resources, South-East of Western Siberia.
