Synthesis, properties and application of modern chemical reagents for increasing oil production
M.M. Asadov Dr. in Ch. Sc. - SRI “Geotechnological Problems of Oil, Gas, and Chemistry”Extraction of residual oil from low-permeability reservoirs remains a significant technical challenge, while conventional enhanced oil recovery (EOR) methods often demonstrate limited efficiency. One of the key strategies to increase oil recovery is the development and implementation of advanced chemical agents designed to improve displacement efficiency. Recent advances in nanotechnology have stimulated growing interest in nanofluids, nanogels and nanocomposites as next-generation EOR agents.
Nanofluids and hybrid nanosystems, such as SAIL–Al₂O₃ + PVP, have shown promising performance in interfacial tension reduction, wettability alteration and improvement of microscopic displacement efficiency. However, issues related to aggregation, stability loss and reduced compatibility with reservoir conditions restrict their large-scale implementation. Continued research is therefore required to identify optimal nanofluid formulations and injection strategies.
Based on the analysis of recent years’ experiences, for example, in γ-Al₂O₃-based nanofluids and nanocomposites, analyzes their stability, physicochemical behavior in reservoir environments and mechanisms of enhanced residual oil displacement. The results highlight the importance of considering the evolution of physicochemical properties under reservoir conditions and optimizing composition to achieve reliable EOR performance.
