The Cambrian Domanikoid deposits of the Kuonamskaya Formation and its age and facies analogs, which are widespread in the Siberian Platform, in terms of their enrichment in sapropelic OM, are on a par with such well-known strata as the Bazhenovskaya Formation in Western Siberia or the Domanik of the Russian Platform. The similarity of the lithological composition, enrichment in bituminous matter, makes it possible to consider them as a possible source of unconventional hydrocarbon raw materials. For the territory of Western Yakutia, the predictive assessment of these deposits is given, blocks characterized by a certain structure, depth of its submergence, and temperature regime of the Kuonamskaya Formation are identified. The territory of distribution of the Kuonamskaya deposits promising for the identification of «shale» oil is divided into blocks with the estimation of undiscovered oil resources by D2 category. Proposals are given on the directions of geological exploration aimed at identifying the commercial oil content of the Kuonamskaya deposits.

Keywords: Domanikoid deposits, Kuonamskaya Formation, oil content, deep wells, prospecting and evaluation works.
