Development of an environmentally friendly composition based on biodegradable surfactants and silicon oxide nanoparticles for enhancing oil recovery Vladimir A. Zhigarev, Elena I. Lesik, Mikhail A. Kuptsov Bulletin of the Tomsk Polytechnic University Geo Assets Engineering, 2026 Relevance. Enhanced oil recovery methods have attracted considerable attention worldwide due to the significant reduction in available oil resources. However, there are many problems and limitations, such as high costs, low sweep efficiency and possible formation damage, that hinder the improvement of these methods. The article discusses issues related to increasing the efficiency of oil displacement. Aim. Development of an environmentally friendly composition based on biodegradable surfactants and silicon oxide nanoparticles to enhance oil recovery. Methods. Experimental studies, statistical methods. Results and conclusions. The article considers the efficiency of using "green" surfactants for flooding formations of Eastern Siberian fields. The authors have tested and improved the methodology for assessing the efficiency of oil-washing ability of surfactants. Based on the results of the work, the authors determined and assessed the characteristics of the considered non-ionic surfactants in terms of increasing oil recovery. When using solutions of the considered surfactants as a displacement agent, it was possible to achieve oil recovery indices higher than when using formation water. This proves the feasibility of using "green" surfactants to increase oil recovery. Analysis of the research results showed that modification of surfactant solutions with nanoparticles allows in some cases further increasing the oil displacement coefficient. The addition of nanoparticles to TWEEN-80 and Polysorbate-20 solutions led to a significant increase in the oil displacement coefficient compared to the original solutions. In particular, it was shown that the addition of 10 nm silicon oxide nanoparticles to a 0.5% concentration of TWEEN-80 solution increases the oil displacement coefficient by 12.5% compared to formation water, and by 9.4% compared to a TWEEN solution without nanoadditives.

A Systematic Computational Study of Oil Displacement Processes in Terrigenous and Cavernous-Fractured Porous Media Using Surfactant Solutions Dmitriy Guzei, Maksim Pryazhnikov, Sofia Ivanova, Vladimir Zhigarev, Andrey Minakov Modelling, 2025 This paper presents the results of a numerical simulation of oil displacement from models of terrigenous and cavernous-fractured media using solutions of the anionic surfactant (sodium laureth sulfate). The surfactant concentration was varied from 0 to 0.1 wt.%. The simulations employed a mathematical model for the flow of immiscible liquids based on the VOF method. The model incorporated experimentally measured interfacial tension coefficients and wettability parameters for the surfactant solutions. The results demonstrate that increasing the surfactant concentration enhances the oil displacement coefficient: by 15% for the terrigenous model and by 19% for the cavernous-fractured model compared to water flooding (at 0 wt.% surfactant), achieving a maximum at a concentration of 0.1 wt.%. The influence of potential mechanisms leading to the improved oil displacement coefficient during surfactant solution injection was investigated. It was established that at a fixed displacement rate, the addition of the surfactant causes a local increase in the generalized capillary number by a factor of approximately 3.7. This is identified as the primary mechanism for the observed enhancement of the oil displacement coefficient in this case. The data obtained in this study can be used for further improvement of surfactant flooding technologies for enhanced oil recovery.
Comprehensive Study of the Efficiency of Low-Concentration Nanoemulsions with Diesel Fuel for Enhanced Oil Recovery Andrey Minakov, Vladimir Zhigarev, Angelica Skorobogatova, Dmitriy Guzei, Andrey Pryazhnikov, et al. Colloids and Interfaces, 2025 This article presents the results of experimental studies examining the effectiveness of low-concentration nanoemulsions for enhanced oil recovery (EOR). The maximum volume concentration of diesel fuel in the emulsions did not exceed 1% by volume. The volume concentration of the emulsifier ranged from 0.05% to 0.4%. A method for preparing stable nanoemulsions was developed. The colloidal stability, viscosity, interfacial tension, wettability, and capillary imbibition rate of low-concentration nanoemulsions were studied. Filtration experiments were conducted to study oil displacement on microfluidic chips simulating a porous medium and core samples. This is the first systematic study of the properties of nanoemulsions containing diesel fuel. It was demonstrated that the developed emulsions have high potential for EOR. It was shown that increasing the emulsifier concentration reduces the contact angle from 35 to 16 degrees and halves the surface tension coefficient. Experiments studying the capillary imbibition of oil-saturated cores with nanoemulsions also confirmed their ability to reduce interfacial tension and improve rock wettability. Oil displacement efficiency during capillary imbibition increases by 22%. Filter tests on microfluidic chips and core samples confirmed the high efficiency of the developed nanoemulsions. Increasing the emulsifier concentration in the emulsion to 0.4% increases the displacement efficiency from 32% for water displacement to 57% for nanoemulsion displacement. Core tests showed that additional injection of nanoemulsions significantly increases the oil displacement efficiency by 10–14%, depending on the emulsifier concentration in the nanoemulsion. It was also established that the use of an aqueous solution of an emulsifier without a hydrocarbon phase does not provide such a significant increase in the displacement coefficient as in the emulsion composition.
