In terms of commerciality, the primary objective of exploration activities in the region is a prospecting for oil pools associated with stratigraphic and hybrid traps widely occurring in the clinoform sequence. New data were obtained in 2014–2020 as a result of exploration activities carried out both by subsoil users and within the framework of state programs. These data make possible the considerable enlargement of high-promising territories and identification of independent oil accumulation zones in the clinoform sequence of the Yenisei-Khatanga regional trough. The authors discuss architecture of the clinoform sequence, define the criteria to identify oil saturation zones and certain oil-promising objects, which made it possible to provide substantial growth of oil resources.
