The current state of the oil and gas industry of Ukraine and the possibility of increasing the hydrocarbon base due to the introduction of fields with compacted reservoirs, which contain significant gas resources. Some methods of intensification of wells that are used in Ukraine, such as hydraulic fracturing and the GasGun method, are considered. Their main shortcomings are given: unforeseen situations of depressurization of the water horizon, use of large volumes of water, utilization of process water, incomplete release of rupture fluid from the reservoir, swelling and hydration of clay components of the reservoir, impossibility of use at extremely high temperatures and pressures. The world modern technologies based on the action of inert gases in hydrocarbon production are covered. Studies on the application of anhydrous rock breaks and intensification methods using inert gases are analyzed. The application of the method of pneumatic compaction of coal seams in Ukraine with the use of flue gases for the release of methane and degassing of coal mines is presented. Modern studies on the use of liquid nitrogen and liquefied carbon dioxide as fracturing agents with rocks with low filtration–capacity properties are presented. The main advantages of using nitrogen, liquefied and supercritical carbon dioxide as reservoir decompression agents are presented. It is proposed to study the method of pneumatic compaction on different samples of rocks in the laboratory using various agents and surfactants, select the appropriate reagents and develop technology for pneumatic rupture of hydrocarbon reservoirs as a cheap and environmentally friendly alternative to existing methods.

Экономической составляющей нашей страны была и остается топливно-энергетическая промышленность, в частности нефтегазовая отрасль промышленности. Снижение объемов добычи жидких углеводородов из-за истощения огромного количества эксплуатируемых скважин заставляет искать пути решения возникающих проблем. Одним из решений такого рода проблем видится увеличение числа эксплуатации нефтегазовых скважин, которые сталкиваются с проблемами из-за высокого содержания в составе вредных компонентов, в частности сероводорода. Ведущие нефтяные компании имеют свое видение решения этих проблем. Исследования ученых в этой области предлагают свои решения подобного рода вопросов. Одним из таких предложений является разработка технологии утилизации сероводорода путем окисления газов кислородом воздуха на твердых катализаторах. В статье предлагается метод выделения серы из высококонцентрированного сероводородсодержащего газа в кипящем слое катализатора. Авторами проведены испытания предлагаемого метода на опытной установке и даны рекомендации по проведению такого рода исследований. The economic component of our country has been and remains the fuel and energy industry, in particular the oil and gas industry. The decline in liquid hydrocarbon production, due to the depletion of a huge number of exploited wells, makes us look for ways to solve the problems that arise. One of the solutions to this kind of problems seems to be an increase in the number of oil and gas wells that encounter problems due to the high content of harmful components, in particular hydrogen sulfide. Leading oil campaigns have their own vision for solving these problems. Researches of scientists in this area offer their solutions to this kind of issues. One of such proposals is the development of technology for the utilization of hydrogen sulfide by oxidizing gases with atmospheric oxygen on solid catalysts. The article proposes a method for the separation of sulfur from highly concentrated hydrogen sulfide-containing gas in a fluidized bed of catalyst. The authors tested the proposed method in a pilot plant and made recommendations for conducting this kind of research.

Carbon dioxide (CO2) corrosion is one of the most dangerous types of destruction of metal products in the oil and gas industry. The field steel pipelines and tubing run the highest risk. Laboratory tests are carried out to assess the resistance of steels to carbon dioxide corrosion. However, unified requirements for certain test parameters are currently absent in the regulatory documentation. We present the results of studying the effect of the parameters of laboratory tests on the assessment of the resistance of steels to CO2 corrosion. It is shown that change in the parameters of CO2 concentration, chemical composition of the water/brine system, the buffer properties and pH, the roughness of the sample surface, etc., even in the framework of the same laboratory technique, can lead in different test results. The main contribution to the repeatability and reproducibility of test results is made by the concentration of CO2, pH of the water/brine system, and surface roughness of the samples. The results obtained can be used in developing recommendations for the choice of test parameters to ensure a satisfactory convergence of the results gained in different laboratories, as well as in elaborating of a unified method for assessing the resistance of steels to carbon dioxide corrosion.

Paper analyzes the prospects of biofuels second and third generation in the structure of the global energy balance, demonstrates a sharp decline in oil and gas revenues in the Russian budget, describes advantages and disadvantages of biodiesel and bioethanol production. The connection between the growth of Russia’s export potential in terms of hydrocarbon products processing with EU standards implementation has been proved. The problems of the realization of programs on the oxygenate technologies development in the Union State of Russia-Belarus were revealed. The capacity of the market of 3-4 generations fuel with using non-food raw materials and various types of biomass was estimated. Was proved that at a high level of growth in business value and profitability of production there are incentives to organize deep processing in Russia’s hydrocarbon production. It is proved that the oil and gas industry in a creative economy should increase its science intensity and depth of raw materials processing, including ones in related industries.
