Efficiency estimation of nanotechnologies applied in constructed wells to accelerate field development

The modern stage of development of the oil industry in Russia is characterized by the necessity to develop intensively small and medium-sized oil fields containing the reserves related to the category of hardrecoverable but associated with the regions with developed industrial infrastructure. Limited input of them in development in previous years was due to the lack of innovative technologies that could significantly reduce the cost of extracted products and to reach the level of economic profitability. The creation and use of new technologies, including nanosystems, reasonable application of them, the government's different types of preferences when developing such facilities allow us to consider them as substantial reserve of oil production. One of the most important things that improve technical and economic performance of the development of low-producing deposits with hardrecoverable reserves is the intensification of reserves recovery, from the very beginning of the operation of the facilities. The availability of wide range of technologies for primary and secondary formation exposing in well construction completion process, methods of influence on the bottom-hole zone, the use of various well designs require proper comparative evaluation of the effectiveness of these activities in different geologic conditions to justify their effective use and reduce risks of ineffective decision making. For field situation in Western Siberia a study of dynamics of bottom-hole area purification degree change and productivity factor was conducted according to the data obtained from operation of producing wells. The paper describes the dependencies and models underlying the various algorithms to evaluate the effectiveness of formation exposing and impact on well bottom-hole zone with the purpose to intensify the process of oil extraction, to reduce the cost of extracted products and profitability increase when setting fields with hard to recover reserves into operation and further development of them. The obtained results, methods and algorithms make it possible to increase efficiency of evaluation of nanotechnologies application outcome including application of nanosystems in well construction completion process. This is the basis for searching and proving technological solutions aimed at extension of resource base deposits that are within the borders of economic feasibility.
