The relevance of the technical and economic evaluation of options for the optimization of electrification projects of hydrocarbon production facilities is due to the growing need for the development of new fields in undeveloped and hard-to-reach territories. Development of new fields requires the construction of large amounts of infrastructure energy facilities, new solutions to improve energy efficiency, reducing capital intensity of projects, solutions to improve the efficiency of resource use in the circular economy, and the use of renewable energy sources (RES). Analysis of the technological directions of electrification of hydrocarbon production facilities proves that the low level of application of RES for energy supply purposes is due to the lack of experimental data on the implementation of this kind of project. This study considers features of technological solutions, practical recommendations, and the main limitations of the application of a hybrid automated system based on RES for the electrification of gas production facilities located in poorly-developed territories. A comparative technical and economic analysis of electrification options using autonomous RES and construction of a power transmission line (PTL) to a remote section of an oil and gas condensate field located in the Arctic zone was carried out. In order to justify the implementation of the electrification project with the use of RES sources, the climatic potential of the region was assessed, and the calculation of energy supply needs and a comparison of alternatives on the basis of specific total capital and operating costs were provided. Assessment of the specific indicator of costs for the proposed variant of the autonomous energy complex based on wind generation indicated savings of RUB 2.24 per kilowatt-hour of energy used. The results of the study can be used in project planning and evaluation of proposed technological solutions based on the rational choice of energy sources and optimization of cost indicators for the construction and operation of energy supply systems.

The latest technologies for climate change mitigation are carbon capture and storage (CCS). Some countries are developing CCS projects, and they are currently at different stages of deployment. Despite the signing of international agreements on climate change mitigation, Russia’s efforts to develop and implement CCS technologies are quite limited. Therefore, it is vital that people are aware of the importance of carbon dioxide capture, utilization, and storage. The purpose of this article is to produce guidelines and toolkits to form a system of measures aimed at raising awareness of the Russian society on carbon dioxide capture and storage technologies. The paper discusses the key findings of several recent studies on the topic, e.g., a study focusing on the level of environmental consciousness among St. Petersburg students; a content analysis of the Russian school textbooks; a study of environmental groups in Russian social media; and an experimental study on creating eco-comics and posters as educational tools for promoting environmental awareness. A multi-level system of educational activities is proposed, including events for preschoolers, schoolchildren, students, and adults.

The relevance of this study is due to the low rate of development of the downstream sectors of Russian oil companies. Against a background of the sale of significant volumes of oil and gas raw materials, Russia lags behind world leaders in the production and consumption of petrochemical and chemical products, with their share in the gross domestic product of the country being only 1.1%. Connected to this is the issue of substantiating strategies of development for the downstream sectors of Russian oil companies, which requires detailed research. In this light, it is necessary to take into account current trends in the worldwide demand on petroleum products and also the opportunities and competitive advantages of Russian oil and gas companies in the creation and development of refineries with a consideration of modern technological, environmental, social and market criteria. The paper tests hypotheses about modernisation as a process of increasing efficiency in the development of the industry as a whole. The results of the study show that the planned pace of development in the industry by means of modernisation proves to be insufficient and requires additional investments in innovative development and new construction. The value of the research lies in the modelling of modernisation strategy options by the example of a large oil company, the estimation of results by the criteria of world average indices of technological efficiency of production and the analysis of these results by state indicators of branch development. The theoretical significance of the research lies in the possibility of using this research approach as an analogue.

In the face of today’s global challenges, oil and gas companies must define long-term priorities and opportunities in implementing complex Arctic offshore projects, taking into account environmental, economic, technological and social aspects. In this regard, ensuring strategic sustainability is the basis for long-term development. The aim of the study is to analyze existing approaches to the concept of “strategic sustainability” of an offshore Arctic oil and gas project and to develop a methodological approach to assessing the strategic sustainability of offshore oil and gas projects. In the theoretical part of the study, the approaches to defining strategic sustainability were reviewed, and their classification was completed, and the most appropriate definition of strategic sustainability for an offshore oil and gas project was chosen. The method of hierarchy analysis was used for strategic sustainability assessment. Specific criteria have been proposed to reflect the technical, geological, investment, social and environmental characteristics important to the offshore oil and gas project. The strategic sustainability of 5 offshore oil and gas projects was analyzed using an expert survey as part of the hierarchy analysis method. Recommendations were made on the development of an offshore project management system to facilitate the emergence of new criteria and improve the quality of the strategic sustainability assessment of offshore projects in the Arctic.

This paper discusses the results of the study of educational effectiveness at the tertiary level. It contains an overview of the research considering the quality and effectiveness of higher education development, the issues of creating criteria for their assessment and measurement. The four groups of factors (“Man”, “Milieu”, “Material”, “Method”) for evaluating educational effectiveness were determined, totally including 65 points. The results of the students’ surveys revealed the most significant factors as well as the least crucial ones influencing educational effectiveness in higher educational institutions. The total number of respondents was 279. It was found that the subgroup of factors “Teacher’s competence” is the most important from the viewpoint of the respondents, while the subgroup “Infrastructure facilities” is the least valuable one. The priority measures list was given, the implementation of which will make it possible to increase educational effectiveness in higher educational institutions. Methods such as Ishikawa diagram building, brainstorming and the survey of students were used for achieving the objectives of this research.
