The research is based on the materials of the largest oil and gas companies in Russia and China, whose total production in each country exceeds 86%. The authors used indicators that are available to the world statistics and relate to the system of sustainable financial growth in Russia and China from 1996 to 2016. The aim of the article is to study the impact of investments in personnel social welfare, energy efficiency and environmental protection on sustainable financial growth of the oil and gas industry. The research objectives are to develop a theory of sustainable financial growth in the oil and gas industry, as well as its assessment and forecasting tools. The authors use the methods of statistical analysis of financial, social, energy and environmental coefficients, and mathematical modeling. They propose a new methodology for calculating the index of the financial sustainable growth system. The authors substantiate the composition and the structure of the sustainable financial growth system of oil and gas companies in Russia and China, as well as the composition of the economic processes that influence or predetermine this growth. The relationship between the subsystem indicators were analyzed in the article. The article substantiates the index of the sustainable financial growth system of oil and gas companies in Russia and China. The authors developed a model for calculating the index of the sustainable financial growth system in the AnyLogic program. The results of the study showed that the factors of the “energy efficiency” and “social subsystem” subsystems affect financial sustainable growth in Russian oil and gas companies, but the financial subsystem is least dependent on the “environment” subsystem. The situation in Chinese oil and gas companies is the opposite: the financial sustainable growth is mostly affected by the factors of the “environment” and “energy efficiency” subsystems. The financial subsystem is least connected with the subsystem of personnel social welfare. Nevertheless, the study proves that in the oil and gas companies in both countries, nonfinancial indicators (each country has its own block) have a positive effect on the financial sustainable growth. According to the authors, the main conclusion is to consider social, energy and environmental indicators that have the strongest influence on the financial sustainable growth in the company’s financial statements. The developed AnyLogic model can be used to predict the index of the sustainable growth system and its management. The results of the study are recommended for the oil and gas corporations of China.

Achieving synergies from high-tech industries in combination with environmental technologies of innovative subsurface use is possible only on the path to the formation of a qualitatively new approach to creation of energy-efficient technologies including assistive technologies. The lack of adaptability of turbomachines providing industrial safety by more than 15% increases the cost of production of mining and oil and gas complexes of the Russian Federation, reducing their competitiveness due to their low energy efficiency. An equation is derived in the article for calculating the circulation of a circular lattice of aero-gas-dynamic profiles as a function of the energy parameters of the sources and vortex chambers drains associated with the energy efficiency of turbomachines. The dominant influence of jet control over the flow profiles of impeller blades is proved due to the energy characteristics of sources and drains, which are associated with the parameters of the mine network. Improving the methodology for the aerodynamic calculation of circular lattice of aerodynamic profiles and the development of radial aerodynamic schemes with increased adaptability made it possible to derive an absolutely unique vector for the future development of fan construction, fundamentally based on nature-like technologies for energy conversion and transfer. The possibility of a significant increase in aerodynamic loading, adaptability and efficiency of mine turbomachines, made according to radial aerodynamic schemes with vortex chambers built into the blades of the impeller, which perform the functions of adaptive inkjet circulation control devices, is proved. According to the results of the research, the VRVP-8 radial-vortex fan was created, which has 55% greater energy efficiency in relation to fans of the VME VV type. Currently, turbomachines are being developed based on nature-like technologies in relation to the oil and gas industry.

The developments of domestic and foreign specialists in the field of improving the energy efficiency of mobile diesel compressor stations of the oil and gas industry is studied. The disadvantages of existing mobile diesel compressor stations in terms of their energy efficiency are identified. Theoretical studies of energy efficiency directions and designs of existing mobile diesel compressor stations have been carried out. It has been studied that for efficient operation of a compressor station it is rational to increase the load of compressors and organize the operation of equipment in energy-efficient modes. Ways to improve the energy efficiency of mobile diesel compressor stations with various options are proposed. It has been established that the optimal way to increase energy efficiency is to reduce the gas temperature to lower temperatures, in comparison with the existing gas cooling systems of compressor stations. It is found that with an increase in the degree of pressure, the savings in gas compression for a compressor with a promising scheme for intermediate gas cooling also increase. An indicator diagram of compressor stations with various cooling schemes has been built. The scheme of the existing system of multi-stage gas cooling of mobile diesel compressor stations is investigated. An improved energy-efficient cooling system for compressed gas by using the heat of compression of gases is proposed. The conclusion about the existence of a reserve to reduce the energy costs of compression due to the use of a coolant-cooler with a temperature significantly lower than the ambient temperature is presented. The description of the working processes of mobile diesel compressor stations according to the existing and perspective schemes is made.

Energy efficiency and emission control has traditionally been a priority area in refining and petrochemical industries. In the last 15–20 years these issues has increasingly been focused in the upstream oil and gas industry. Emission taxes and commitment from the industry has led to significant improvements. Energy consumption and emission to air, especially CO2 and NOx has been reduced by typically between 10 to 30% by relatively simple and cost-effective methods. In parallel, change in design practise for new plants has contributed to similar reductions. This paper outlines the analysis and methods used and the results achieved.
