New data obtained over the period of 2014–2019 as a result of geological exploration on the Taymyr Peninsula both by subsoil users and in the programmes of the Federal subsoil use agency, provide the justification for a substantial expansion of the highly promising areas in the western part of the Yenisey-Khatanga regional trough and delineation of the individual Payyakhskaya oil accumulation zone. Using the example of the Payyakhskoye field, the features of geological structure of accumulations, fields and promising targets of the Payyakhskaya zone are considered, criteria for the predicting sand bodies oil content of the Achimovskiy type in the composition of the Lower Cretaceous Shuratovskaya Formation are outlined, it made possible to clarify the resource potential of the research area and to ensure a significant increase in oil resources.

Keywords: Yenisey-Khatanga regional trough, Yenisey-Khatanga petroleum region, Payyakhskaya oil accumulation zone, Payyakhskoe field, Neocomian clinoform structure, Shuratovskaya Formation, Achimovskaya stratum.
