Ontogenesis of hydrocarbons in the mesozoic sedimentary basin and the pre-jurassic rock complex located in the south-eastern part of the Western Siberia
Studying of parametric wells sections drilled in Tomsk region in recent years, namely, Vostochno-Pajduginskaya No.1 (VP-1), Yuzhno-Pyzhinskaya No.1 (YuP-1), Vostok-1 (V-1), Vostok-3 (V-3), with the assistance of the existing data on the territory’s geology, geochemical characteristic of the dispersed organic matter (DOM) and the patterns of oil and gas windows distribution, allows identifying Pre-Jurassic rock complex as the main source and the new promising object of prospecting for hydrocarbon accumulation located in the south-eastern part of the Western Siberia.
