“…A practical example shows a reduction in the overshoot time. Compared to previously proposed methods [10,23,29,[73][74][75][76][77][78][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139], the time spent on equalizing the reservoir pressure is reduced by 15%. It is important to note not only the great theoretical significance of the research conducted, but also its real practical application.…”

The most important source of human life support is water. During the development of mineral water fields, unsustainable patterns of production and consumption have been observed, which could lead to environmental damage and the deterioration of mineral water quality and sources. In this work, a procedure for determining the modified link’s parameters, replacing the static and dynamic indicators of the hydrodynamic process, is proposed. Recording the parameters at the different filtration coefficients along the spatial coordinates allows the environmental safety of aquifers to be increased and the pressure of the reservoir to be stabilized. The presented approach allows the accuracy of the process used to control the reservoir’s pressure to be increased.

“…The construction of this unit will help to achieve the following results: an increase in the production of diesel fuel of the fifth ecological class by 1 million tons, the production of components of motor gasoline by 340 thousand tons per year and liquefied gases by 57 thousand tons. The complex will also include units for the production of hydrogen and elemental sulphur [38][39][40]. In the future, the products produced will be in demand in the Altai Territory, and it is also possible to sell the goods abroad due to its proximity with, for example, China, Kazakhstan and Mongolia.…”

Evaluating the Downstream Development Strategy of Oil Companies: The Case of Rosneft

et al. 2022

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.

This study presents a mathematical model to evaluate the performance of gas pipelines during hydrogen injection in a gas pipeline-compressor station. The developed model presents the calculation of methane–hydrogen mixture (CH4/H2) transportation through the compressor station, where the compensation of pressure drops in the mass and energy balance takes place. Simultaneously, in the operation of the centrifugal blower system of gas compressor stations, the emissions of CO2 are considered, considering the mixing of gas media and the compression of CH4/H2. This mathematical model is realized for the pipeline transportation of hydrogen, at which the principle of mixture expansion occurs. The aim is to solve the problem of CO2 emissions at compressor stations. The optimization procedure has been formulated using a system of nonlinear algebraic equalities. The research focuses on the adaptation of existing gas transportation systems to CH4/H2 transportation and the impact of environmental risks on the operation of compressor station equipment. In this case, it is possible to determine the quantitative amount of hydrogen that can be added to natural gas. By solving the problem of finding the inner point of sets using the system of nonlinear algebraic equalities, it is possible to obtain the control parameters for safety control of technological modes of CH4/H2 mixture transportation. The study findings reveal that the consumption of gas charger and hydrogen was 50.67 and 0.184 kg/s, respectively, and the estimated efficiency resulting from the modified turbine design was 75.1 percent. These results indicate that the equipment operates more efficiently when hydrogen is being transported. The numerical analytical results indicated in this study hold practical significance for design applications. It will assist in identifying and evaluating the restrictions that may develop during the technological, operational, and design stages of decision-making.
