Assessment Results

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.

The evolutionary-genetic method, whereby modern sedimentary basins are interpreted as end-products of a long geological evolution of a system of conjugate palaeo-basins, enables the assessment of the petroleum potential of the Western sector of the Russian Arctic. Modern basins in this region contain relics of palaeo-basins of a certain tectonotype formed in varying geodynamic regimes. Petroleum potential estimates of the Western Arctic vary broadly—from 34.7 to more than 100 billion tons of oil equivalent with the share of liquid hydrocarbons from 5.3 to 13.4 billion tons of oil equivalent. At each stage of the development of palaeo-basins, favourable geological, geochemical and thermobaric conditions have emerged and determined the processes of oil and gas formation, migration, accumulation, and subsequent redistribution between different complexes. The most recent stage of basin formation is of crucial importance for the modern distribution of hydrocarbon accumulations. The primary evolutionary-genetic sequence associated with the oil and gas formation regime of a certain type is crucial for the assessment of petroleum potential. Tectonic schemes of individual crustal layers of the Western sector of the Russian Arctic have been compiled based on the interpretation of several seismic data sets. These schemes are accompanied by cross-sections of the Earth’s crust alongside reference geophysical profiles (geo-traverses). A tectonic scheme of the consolidated basement shows the location and nature of tectonic boundaries of cratons and platform plates with Grenvillian basement as well as Baikalian, Caledonian, Hercynian, and Early Cimmerian fold areas. Four groups of sedimentary basins are distinguished on the tectonic scheme of the platform cover according to the age of its formation: (1) Riphean-Mesozoic on the Early Precambrian basement; (2) Paleozoic-Cenozoic on the Baikalian and Grenvillian basements; (3) Late Paleozoic-Cenozoic on the Caledonian basement; (4) Mesozoic-Cenozoic, overlying a consolidated basement of different ages. Fragments of reference sections along geo-traverses illustrate features of the deep structure of the main geo-structures of the Arctic shelf and continental regions of polar Russia.

The qualitative and quantitative assessment of ground waters protectability based on the regional specific charac-teristics of the lithology and thickness of impermeable deposits of the zone of aeration and overlying deposits, a ratio of confined and ground water levels, the soils and clay rocks absorptivity. The article gives the author's vision of ground waters natural protectability. It presents a quantitative estimation by three most well-known methods. Based on the calculations made a map of protectability of fresh ground waters in the Atlym-Novomikhailovsk complex for Nizhnevartovsk district was constructed.

In the conditions of price reduction in the world energy market, the issue of determining the priorities of the economic development of hydrocarbons in the Arctic Region of the Russian Federation (RF) becomes highly relevant. The article is aimed at developing an optimal model for the spatial organization of energy resources in the Arctic Region. The expert elicitation procedure was used to determine the efficiency indicators for the economic development of the oil-and-gas-bearing areas in the Arctic Region and clusterization of these areas was carried out in terms of economic efficiency. Based on the factor analysis, the degree of influence of efficiency indicators on the economic development of the oil and gas bearing areas of the region was determined and, an integrated performance indicator of economic development for oil-and-gas-bearing areas for each cluster was calculated with regard to the factor loadings. A 3-D model was developed for the organization of economic development of oil and gas in the Arctic Region. The 3-D model became the basis for determining the priorities for territorial exploration, development and production of hydrocarbons in terms of their economic efficiency, taking into account the trends in the development of the world energy market and break-even fields. A set of recommendations was developed to improve the efficiency of the spatial organization of economic development of oil and gas in the Arctic Region. The implementation of the proposed measures can contribute to the development of the oil and gas industry in the region, its socio-economic development and the long-term sustainability of Russia's energy security.

Resources Development

The Yamal oil and gas province (OGP) is strategically important for the Russian gas industry. In the coming decade, gas production in Yamal is expected to grow to 180–200 billion cubic meters per year. The main goal of the article is to solve a scientific problem consisting in the study of the spatial organization of the development of gas resources, determination of the rational structure of reproduction of natural gas reserves in the Yamal oil-gas-bearing region in the context of the modernization of the Arctic gas industry complex. The article assessed the gas resources of Yamal, revealed trends in the economic development of natural gas fields, presented the characteristics of investment projects based on the fields being developed. An analysis was carried out that made it possible to differentiate the deposits by the degree of their prospects, and a strategy for expanding the hydrocarbon potential of Yamal was determined. It was revealed that the main areas of production in the Yamal oil-gas-bearing region are associated with the development of deposits with a high level of Cenomanian deposits. Such deposits are characterized by a higher increase in the capitalization and profitability of investment projects in real time compared to fields located in the northern and far eastern seas, including on the shelf of the Kara Sea. It was concluded that the strategy for the reproduction of hydrocarbon potential will be aimed at conducting prospecting and exploration in order to transfer forecast resources to industrial reserves of natural gas. The study applies a general scientific methodology providing for systemic and comprehensive approaches to justify the spatial organisation of gas resources development in the Yamal oil and gas bearing region. A significant body of factual material on the state of free gas and condensate reserves in Yamal has been analyzed. The results of the research were obtained with the use of comparative-analytical, statistical methods of economic analysis.
