High-quality managerial decision-making is crucial for improving the resource efficiency of production companies in the context of digitalization. Currently, the use of modern methods and tools to manage the consumption and supply of resources of companies should consider the principles of a circular economy. This study focused on the development of a mechanism to manage resource efficiency in the fuel and energy sector. It used the methodological tools developed by the authors, including a comprehensive integral assessment of resource efficiency and a practice-oriented research methodology adapted for fuel and energy enterprises. Having analyzed the existing state of resource consumption, the authors discovered a disparity of indicators, methods and means in the applied assessment of the accounting, control and expenditure of energy resources. Using the analytic hierarchy process as a foundation, the authors applied a technique for identifying inefficient production processes at the fuel and energy enterprises level as a case study. With the proposed technique, the main areas of the inefficient use of resources were identified. They include the organization of accounting, control and rationing of resource consumption, supplying the resources to production, and measures to improve resource conservation. These areas were ranked by importance and priority. The calculations determined the most resource-intensive process—“Operation of equipment and technologies”. On this basis, the authors developed a methodology for resource efficiency management, including a number of digital technologies and tools. As a result of testing the developed mechanism in an oil and gas company based on the principles of a circular economy, the authors found reserves of the inefficient use of energy resources and searched for the best option for the development of an oil and gas company. Moreover, the proposed approach enabled the authors to determine the balanced growth of the company’s resource efficiency, develop managerial decisions for the its long-term development, and conduct its environmental and economic assessment.

The article proposes a methodological approach to creating a project-management strategy for energy conservation and energy efficiency in the sectors of the gas industry, which reflects the peculiarities of the industry in the contemporary institutional environment, evaluates a set of alternative scenarios and investment projects of the subject of geopolitical factors, uncertainty and probabilistic characteristic of expected economic, environmental, and social effects.

The complex modern trends in the growth of the consumption of raw hydrocarbon materials around the world, and as a consequence their accelerated depletion, have forced oil and gas industry enterprises to identify progressive resource-saving methods and technologies. Such methods could enable the environmental and technological effects of production processes to be achieved under conditions of sustainable economic development and with a policy of balanced consumption and resource provision. This research is devoted to the improvement of the scientific and methodological foundations and the development of predictive and analytical tools for assessing the efficiency of resource use in gas industry enterprises. With the application of the proposed instruments, we carry out simulation modeling of the efficiency of natural gas production, processing and pipeline transportation companies. In the course of a comparative analysis of the efficiency indicators for Russian gas companies, a resource-efficient variant of their development is selected and the most promising business projects are identified. Three branch companies of the Russian gas industry are accepted as the objects of the research in this study. As a result of the conducted approbation process, it is revealed that the existing practice of assessing consumption and resource provision in companies in the industry, as well as the use of methods and approaches to resource conservation, does not have a single and complex character. The methodology proposed by the authors makes it possible to approach industry companies with the same set of indicators, systematize and calculate them, identify existing unused reserves for resource conservation and identify promising resource-efficient projects.

Subject. Monitoring and predicting the trajectories of the development of regions on the basis of the Leontief balance model. Objectives. Development of the balance tables estimating schemes for the south of the Tyumen Oblast according to statistical data of typical economic indicators. Methods. Two options for solving the problem of estimating balance tables are considered. In the first variant the reference matrix of direct costs is adjusted to the statistical data of the system of national accounts for the Tyumen Oblast. The second variant is to use the industry cost structure for Russia to customize the regional table. Results. In the first approximation, the structure of aggregation of industries into subsystems was chosen in accordance with the development strategy of the Tyumen Oblast until 2030. The obtained images of the tables correspond to the balance ratios and productivity conditions of the Leontief matrix. Conclusions. The results of adjusting the input-output model for the south of the Tyumen Oblast according to the available statistical data in general demonstrate the efficiency of the presented methods for assessing direct cost matrices. The choice of the structure of aggregation of indicators in accordance with the development strategy of the region allows to compare the predicted and model trajectories of economic development for characteristic groups of industries.

The article deals with various technologies for the oil rims preparation of Zapolyarnoye oil and gas condensate field. The following circuits were considered for the selection of the technology of preparation of extracted fluid: low-temperature separation (STC); low-temperature condensation (LTC); a low-temperature rectification (NTR); low-temperature absorption (LTA); membrane technology (Mt). Diagrams of these processes were collected and tested in the system HYSYS process simulation. Efficiency analysis of hydrocarbon raw materials preparation on the basis of functions, selection of components and narrow fractions.
