Opis:: This article describes the design of photo catalyst reactor for oil removing from produced water. Real produced water containing a combination of organic compounds was treated with zinc oxide nanoparticles. In this study, ultraviolet radiations were used to find the efficiency of removing the oil content from the water produced that brought from the Al-Ahdab oilfield in kut/ Iraq by advanced oxidation process (AOP) using (ZnO/UV) in batch system and continuous system. In batch system were studied the effect of zinc oxide concentration (nanoparticles), time of irradiation, and pH. The highest removal rate of oil from the produced water (100%) was obtained during the following optimal conditions: ZnO NPs as catalyst = 55 mg/L, pH =3, at the time of irradiation of 90 minutes in batch experiments. In the continuous system, the effects of flowrate, number of UV-A lamp and time of reaction were studied, the results obtained were the efficiency of decomposition decreases with increasing the flow rate of solution in reactor, the maximum removal efficiency of the process (ZnO/UV) was 80% at 20 mL/min and irradiation time 120 min. In general, zinc oxide is beneficial through its high oil adsorption capacity in addition, It lowers the amount of oil in the produced water.

Opis:: The problem of effective technology for heavy oil recovery nowadays has a great importance, because of worsening geological conditions of the developed deposits, decreasing recovery factor, increasing the part of heavy oil. For the future sustainable development of oil producing industry the involved technologies must require energy effectiveness and ecological safety. The paper proves the enhanced oil recovery methods necessity for heavy oil deposits, highlighted thermal technologies as the most effective. But traditional thermal treatment technologies is a source of air pollutant emission, such as CO, NO etc. The calculation of emissions for traditional steam generator is provided. Besides, the paper shows the effectiveness of electrical enhanced oil recovery methods. The advantages of associated gas as a fuel for cogeneration plants is shown. The main approaches to implementation of carbon dioxide sequestration technologies in the oil and gas industry of Russia are defined. Conceptual view of СО₂-EOR technologies potential within the context of sustainable development of oil and gas industry are presented. On the basis of the conducted research a number of scientific research and practical areas of the CCS technology development are revealed.

Tytuł:: Improvement of Efficiency of Steam-Thermal Treatment of High-Viscous Oil Formations Using Downhole Electric Steam Generators

Opis:: The presented work investigates a method for developing hard-to-recover hydrocarbon reserves based on a downhole electrothermal steam generator, which is distinguished by energy efficiency, resource conservation and environmental safety. The paper presents an overview of downhole electro-thermal equipment that improves the quality of thermal treatment of the bottom-hole zone of high-viscous oil formations by separating steam in an electric steam generator and increasing its dryness, wherein thermal energy in the oil-formation medium affects all its components and completely changes ties and filtration conditions. This is expressed in a decrease in the viscosity of oil, its increased mobility, weakening of structural-mechanical properties, improvement of the conditions for capillary imbibition, and, as a result, an increase in the displacement factor and the final oil recovery. A simulation of the reservoir temperature field was performed by setting the heat flow in the ANSYS software package to understand the thermal processes in the steam generator and to more accurately determine the necessary heating parameters for a given water flow rate. The temperature field of the reservoir simulation after the heat treatment of the bottom-hole zone was conducted in the software package Femlab 3.5. The proposed simulation models can help in the development of the physical model and further research. This technology is environmentally friendly and does not emit emissions into the atmosphere.

Tytuł:: Prospects of CCS Projects Implementation in Russia: Environmental Protection and Economic Opportunities

Opis:: The urgency of environmental protection is determined by its intensive change because of human impact, which, among other things, accompanied by an increasing of carbon dioxide (CO₂) emissions. One of the ways to reduce the emission is Carbon Capture and Storage (CCS) technologies. To date, developed countries have successfully implemented a number of CCS demonstration projects. Their main purpose is to study the effectiveness of CO₂ storage. Russia is one of the world’s largest producers of CO₂ emissions. However, CO₂ capture and storage issues are not studied by Russian enterprises due to the absence of environmental taxes. The experience of developed countries shows that CO₂ storage projects, in addition to the reduction of anthropogenic impact, can be commercially effective not only by reducing the tax burden. This review presents the analysis of international experience in the field of CO₂ capture and storage. Given the immaturity of technology and lack of the necessary volume of statistical data, it was an attempt to determine the minimum conditions, which permit the implementation of CCS projects in Russian oil fields. On the basis of the Russian development forecast and the fuel balance structure the volumes of CO₂ emissions in the 2016–2030 years were calculated. According to significant difference in opinions about the feasibility of CCS implementation in Russia, this review presents the main arguments for and against such projects. Evaluation of the potential effectiveness of CCS projects to enhance oil recovery factor showed that in spite of the absence of CO₂ emissions taxes, such projects could be commercially effective in Russia due to the increase in oil recovery.

Opis:: The objective of this paper is to define the main approaches to the implementation of carbon dioxide sequestration technologies in the oil and gas industry in Russia, and also to identify ecological, economic and social issues of their usage. Promotion of the technology of carbon dioxide (CO₂) sequestration by means of capturing and injecting it into underground reservoirs is a promising mechanism of reducing carbon dioxide concentration. Carbon capture and storage (CCS) technologies might be used to enhance oil recovery (EOR-CO₂) and production by means of oil extraction and decreasing oil viscosity. Conceptual view of the potential of EOR-СО₂ technologies within the context of oil and gas industry sustainable development are presented. Incentives of the CCS projects implementation are identified. On the basis of the conducted research a number of scientific research and practical areas of the CCS technology development are presented.
