Generalization of regional seismic results within the Central Tunguska prospective petroleum region

Abstract

The results of regional geological exploration at the expense of the federal budget on the territory of the Central Tunguska prospective petroleum region located in the Republic of Sakha (Yakutia) over the past 17 years are analyzed. To date, the territory of the Yakut part of the Central Tunguska PPR is closed by modern regional geological exploration by 77.9 %, which allows us to speak about the completion of the regional stage of geological exploration here. It was shown that Vendian terrigenous deposits and Vendian carbonate, subsalt deposits of the Lower Cambrian, as well as carbonates of intersalt deposits of the Cambrian have the greatest prospects for oil and gas potential. Riphean deposits have a limited distribution. Based on the results of these works, promising objects for prospecting work were identified.
