Assessment of the economic efficiency of the use of foaming surfactants in oil and gas fields

Currently, there is a decrease in the share of conventional oil reserves, which requires the application of new technologies for the efficient development of fields. The problem of low extraction coefficients of oil from oil and gas condensate fields, particularly with thin oil rims, is due to the rapid formation of water and gas cones. The aim of this study is to evaluate the effectiveness of using foaming surfactants (surfactants) to improve oil recovery. Various foaming surfactants were used to create foam barriers, and an economic analysis of costs and expected profits from increased production was conducted. The calculation of critical flow rates, barrier water influx, and optimal locations for injection wells was considered. The results showed that oil rims are complex objects with low recovery coefficients. However, the implementation of high-tech solutions, such as the use of surfactants, can significantly enhance development efficiency. The economic analysis confirmed the feasibility of using foaming surfactants, demonstrating that their application may lead to increased profitability. The conclusion emphasizes the importance of integrating modern technologies into the process of developing hard-to-recover reserves for more sustainable and efficient oil production.
