Abstract

Nano-fluid enhanced oil recovery (EOR) is explored as a method to improve oil extraction using nanoparticles. These fluids alter reservoir wettability, reduce interfacial tension, and plug high-permeability zones, enhancing oil recovery. Various nanoparticles, including silica, magnetic, aluminum oxide, cerium oxide, graphene oxide, and titanium dioxide, are investigated for their efficacy in different reservoir conditions. Optimization of nanoparticle properties, concentration, and injection strategies is crucial for maximizing oil recovery and avoiding formation damage. Synergistic effects with other EOR techniques are also highlighted
