摘要

Recent advances in the oil and gas industry are increasingly embracing the revolutionary potential of nanotechnology, viewed through both environmental and economic lenses. Nanoparticles (NPs) have continuously been analysed and applied in many oil-field applications for the past decade. Of all nanomaterials that have been essential research in applied science and engineering, Zinc oxide nanoparticles (ZnO NPs) have received remarkable consideration due to their extraordinary UV-filtering properties, photochemical and antifouling characteristics, high catalytic and antimicrobial activities, thermal stability, rigidity, semiconductivity, piezoelectricity, low toxicity, biodegradability, and biocompatibility. As an amphoteric oxide, ZnO can survive in highly acidic or basic environments; hence, it is helpful in extremely harsh oil-field environments. While many researchers are diligently exploring the impact of various nanotechnologies and nanoparticles on oil and gas operations, there is a pressing need for extensive research into the innovative ecological usefulness of ZnO NPs in oil-field operations owing to their unique traits. This paper comprehensively reviews cutting-edge applications of ZnO NPs as oil-field chemicals, especially in exploration, drilling, production, and wastewater management. Results from previous reports reviewed herein showed that ZnO NPs are excellent drilling-fluid additives, improving rheological properties and wettability of drilling fluids; good corrosion inhibitors for steel; waxy (heavy) crude-oil flow-property improvers; and a perfect enhanced-oil-recovery agent through their actions in inducing wettability change, decreasing viscosity ratios, stabilizing foams or emulsions, and reducing interfacial tension. Lastly, they were proven to be very useful in the treatment of petroleum-refinery wastewater: they exhibited great ability in improving polysulfone membranes for membrane filtration, demonstrated excellent photocatalytic properties, and also showed strong adsorbent ability toward the prevalent heavy metals in petroleum-refinery wastewater. Studies also revealed that incorporating other metal or polymer composites with ZnO NPs enhances their efficacy and uniqueness.
