Abstract
The article presents the results of petroleum potential quantitative forecast of the Toarcian, Pliensbachian and Hettangian-Sinemurian regional reservoirs of Lower Jurassic deep-buried deposits within Yenisei-Khatanga and adjacent territories of the Gydan petroleum regions based on models of structure and reconstructed conditions of formation for each of the noted reservoirs and their components – permeable complexes and fluid seals, developed earlier by the authors of this article. Tectonic, lithological-facies and geochemical criteria for assessing the oil-and-gas bearing prospects of reservoirs are described. The methodology and the petroleum potential quantitative assessment results for regional reservoirs with attached maps of petroleum potential of each reservoir are considered. The structure of hydrocarbon resources (HC) is given: the distribution of initial total hydrocarbon resources by phase composition, regional reservoirs and oil and gas-bearing areas.
