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.

We have assessed the hydrocarbon reserves, including oil, in the waters of the Arctic seas of the Russian Federation. We have considered current projects for extraction of hydrocarbons in the Pechora Sea at the Prirazlomnoye field. We have carried out comprehensive analysis of environmental issues related to operation of oil exploration facilities, describing the prospects for development of offshore hydrocarbon fields on the continental shelf of the Pechora Sea. The valuable ecosystem components of the Pechora sea have been characterized. We have discussed the set of measures developed for reducing environmental risks: organizing a three-tier automated system for oil spill response in any situation, including emergency; using the “zero discharge” approach, in which all human and industrial waste is collected in special closed containers transported to the shore for disposal; vessels of the auxiliary fleet are equipped with the appropriate equipment enabling them to be directly eliminate emergency oil spills; annual oil spill response (OSR) exercises are held; since the terminal is located in a permafrost region, the oil storage tanks were built with double walls (the tank-in-tank principle), which virtually eliminates the risks of oil spills. We have formulated recommendations for maintaining sustainable environmental status of the continental shelf of the Pechora Sea.
