Increasing the profitability of field operation based on optimization of technical and economic indicators

Objective. Improving the profitability of exploitation of brownfields based on technical-economic values optimization takes on great importance at present time. The relevance of these works is connected not only with the technological and economic component, but also to a large extent social, since it is important to maintain and develop the production infrastructure near such fields, which are already located in developed and often densely populated areas of the country.

A promising direction for increasing profitability of exploitation of brownfields is further application, improvement and updating of existing methodological approaches and technologies of physicochemical and hydrodynamic EORs, aimed to stabilization of oil production, decrease in the rate of well production watering, recoverable reserves increment, decrease OPEX.

Materials and methods. The results of assessing the dynamics and degree of oil reserves recovery, calculations of the recoverable reserves increment, technological and economic effect from the implementation of various technologies of physicochemical and hydrodynamic EORs were used.

Results. The article shows the need to improve and update the existing methodological approaches to the application of physicochemical and hydrodynamic EORs technologies as one of the important areas for the development of the fuel and energy industry in the medium term. At the same time, scientific support for EOR projects stands out among the key areas, the purpose of which is a high-quality selection of well treatment area and technologies, evaluation of the effectiveness of technologies and determination of the optimal volumes of injection of chemical components, correct business planning and monthly distribution of the effect, achievement of the technological and economic potential of the main and additional programs physical-chemical and hydrodynamic EOR, decrease unit OPEX.

Conclusion. The individuality of the geologic and physical reservoir characteristics / separate reservoir areas and wells does not allow achieving consistently high results through the use of one universal EOR technology. High technological efficiency and duration of the effect, and, as a result, the profitability index is achieved by targeted treatment using individual compositions of chemicals, treatment designs and technologies for specific conditions of the reservoir / area, taking into account the existing problems, the current field development status and interaction with surrounding wells within a single oil-field exploitation system of a productive layer. Such an approach, based on the principles of treatment of reservoir on systems approach, is one of the ways of rational field development.
