Lithology of vendian terrigenous reservoirs of the south of the Siberian Craton
Vendian aluminosiliciclastic deposits of the southern Siberian Craton is the most prospective stratigraphic level for oil and gas exploration in Eastern Siberia. Lithological factor significantly contributed to the formation of these high-capacity reservoirs. Most of the hydrocarbons are confined to the Upper Vendian petroliferous complex, in particular to the Parfenovskiy productive horizon and its analogs. Deep drilling in central regions of the Angara–Lena Step (ALS) and in the northeastern Nepa–Botuoba Anteclise (NBA) elucidated the composition and structure of these collectors [1].
