The article provides an analytical review of the results of direct geochemical studies of the Vilyui syneclise, one of the promising areas for oil and gas in the east of the Siberian Platform. The work objective is to demonstrate the high ef ciency of direct geochemical sampling for the search for oil and gas deposits in the conditions of a terrigenous section of the studied territory. It is shown that pro le contrast anomalies were identi ed above productive structures. At the same time, a general increase of light hydrocarbon (LH) components from the anks to its center and the con nedness of the most noticeable microconcentrations of heavy hydrocarbons (HH) to the periclinal sections of productive structures have been established. This phenomenon, apparently, indicates the predominant effect of ltration migration through various weakened zones from the source of hydrocarbons (deposits). The results of our own reconnaissance work carried out in 2016 on the southern pericline of the Middle-Vilyui gas condensate deposit are presented. The veri cation work was carried out to evaluate the effectiveness of the equipment and research methods. Relatively high values of benzene and toluene were recorded above the zones of occurrence of deposits T1-IIа and T1-III. It is assumed that the maximum values of B/T can be con ned to the zones of oil accumulations. Based on the conducted geochemical samplings and historical experience, it is concluded that in combination with other geological and geophysical methods, direct geochemical studies will increase the reliability of forecasting the prospects of oil and gas potential of poorly studied territories. A recommendation has been made for the use of geochemical samplings in adjacent territories with a similar geological section.

The northern slope of the Yakut uplift covers the North Aldan oil and gas bearing region and partially the Pre-Verkhoyansk and Vilyui oil and gas bearing regions. The potential oil and gas content of the Northern slope of the Yakut uplift is associated with a wide stratigraphic range of promising sediment complexes (Vendian-Cambrian, Permian-Triassic and Jurassic-Cretaceous). All these complexes have confirmed oil or gas occurrences of varying intensity. Terrigenous-carbonate formations of the Vendian-Cambrian complex are the most promising deposits in terms of oil and gas potential, confined to the lower part of the upper sub-suite of the Yudom formation of the Vendian. A relatively effective fluid seals for the Vendian hydrocarbons can be the variegated formation of the Lower Cambrian, composed of dense mudded-off carbonate rocks. The prospects of Permian-Triassic and Jurassic-Cretaceous sediment complexes will be determined by the absence or presence of zonal and local fluid seals, including non-traditional permafrost hydrate. Thus, several oil and gas complexes of different origin and with different types of fluid seals are identified in the section. A brief overview of the promising oil and gas complexes of the Northern slope of the Yakut uplift emphasizes the need for priority geological exploration for oil and gas. Clarification of geological structure of the studied area will make it possible to identify the most promising zones and sites for planning and organzing exploration work. The work was carried out with financial support within the framework of the State Assignment of the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1 using scientific equipment of the Center for Collective Use of the Federal research center "Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences" within the framework of grant No. 13.TsKP.21.0016.
