This study explores the physicochemical mechanisms involved in oil displacement by aqueous solutions containing nanoagents. It delves into these critical issues and reveals the primary pathways for innovative solutions. The use of nanoparticles in oil recovery processes can significantly enhance the characteristics of the injected fluid. These enhancements include improvements in viscosity and density and reductions in surface tension. Additionally, nanoparticles can help optimise emulsification, leading to more effective oil recovery overall. During nanoflooding, the properties of the rock matrix change, particularly its wettability and heat transfer coefficient, both of which improve. The physicochemical mechanisms of oil displacement by nanoagents are discussed, along with the influence of the adsorption process on displacement efficiency.
