The article discusses ways to increase the oil recovery factor in already developed fields, special attention is paid to the methods of enhanced oil recovery. The comparative structure of oil production in Russia in the medium term is given. The experience of oil and gas companies in the application of enhanced oil recovery in the fields is analyzed and the dynamics of the growth in the use of various enhanced oil recovery in Russia is estimated. With an increase in the number of operations in the fields, the requirements for the selection of candidates inevitably increase, therefore, the work focuses on hydrodynamic modeling of physical and chemical modeling, highlights the features and disadvantages of existing simulators. The main dependences for adequate modeling during polymer flooding are given. The calculation with different concentration of polymer solution is presented, which significantly affects the water cut and further reduction of operating costs for the preparation of the produced fluid. The possibility of creating a specialized hydrodynamic simulator for low-volume chemical enhanced oil recovery is considered, since mainly simulators are applicable for chemical waterflooding and the impact is on the formation as a whole.

The efficiency of different physical and chemical technologies used in various areas and Romashkinskoye New-Elkhovskoye oil fields was researched. The result was a conclusion that at high water-cut objects, restriction of movement of water in highly permeable leached zones of a productive layer is one of the main conditions for increasing the efficiency of not only flooding, but also the use of physical and chemical methods based on improving of oil extraction factor.

Associated gas of coal and minor oil deposits emitting into the atmosphere is considered to be valuable energy resource requiring proper utilization both from the economic and environmental viewpoints. It is proposed to develop mobile gas-hydrate plants to utilize associated gas of mines and minor oil and gas deposits. Hydrogenerating technology to collect and utilize coalmine methane immediately at the degassing wells of coal mines and oil extraction platform has been developed. Thermobaric parameters along with physical and chemical effect upon hydrate-formation process have been substantiated and selected. Certain degree of mechanical impact as well as magnetic field and ultrasound influence upon the process of hydrate formation has been proved. The technology will make it possible to obtain end product within the degassing area for its further transportation to consumers at long distances.

Traditional modern chemical technology methods for solution and liquid mixture component separation are based on the difference between physical and chemical parameters of components being separated (boiling point, solubility). The methods use the phenomenon of phase change. Thus to install the equipment for the processes is quite complicated and power-consuming.As the world population grows we face new problems,i.e. the shortage of drinking water. Different methods are applied for getting drinking water such as distillation and freezing out. Half of all the desalinated water is got by distillation. To solve the arisen problems by using the traditional methods of chemical technology is becoming more and more complicated. Methods of membrane separation have turned out to be promising in this respect.

The article elaborates on the topic about abrupt catagenetical alterations in sedimentary rocks and postulates the topicality and problematics of the study during exploration of new and already existing oil and gas deposits. The goal of the research is the identification of compacted zone which was formed under secondary physical and chemical processes within 110–120 temperature interval (including possible paleotemperature effect). To get the most qualitative/comprehensive results, integrated analysis of lithology, petrophysical characteristics of cored intervals in the slide sections and geological information has been done by the authors. Essential part of the article is devoted to the methodology, study description and interpretation of outcome results. Four gas condensate fields were chosen based on their similarity. They have similar tectonic, structural, generation and accumulation conditions and all of them are located in the axial and pre-axial zone of the central part of Dnieper-Donets basin. After well log data processing and precise microscopy study of slide sections, the authors concluded that 110–120 temperature surfaces, which frame compacted and altered zone (identified by the Ukrainian Research Institute of Gas), have to be shifted according to new research findings. Practical value of this work is to identify compacted and decompacted zones at a great depth, which can be an indirect indicator of traps existence for hydrocarbons and possible manifestations of abnormal pressures.
