Summary In the pursuit of carbon neutrality and mitigation dioxide (CO2) emissions, researchers have been exploring various approaches to integrate capture, utilization, storage (CCUS) with enhanced oil recovery (EOR) techniques. CO2 injection has identified as a promising method reduce crude viscosity enhance its mobility within reservoir. However, high can lead gas fingering, causing channeling reducing sweep efficiency. While foam considered improve conformance during flooding, longevity is negatively affected by harsh reservoir conditions. Polymers, which could be used stabilizers, are limited pressures CO2-induced reduction, hindering their widespread industrial application. Nanofluids, colloidal suspensions nanoparticles in base fluid, emerged potential solution for petroleum industry applications, including wettability alteration, interfacial tension (IFT) efficiency improvement. Functionalized intensifying interactions oil, particularly through adsorption, promises more desirable CO2-EOR.
