    Abstract Image

    Enhancing the crude oil recovery rate is essential for the efficient and sustainable extraction of residual oil from geological formations. Biologically mediated nickel oxide nanoparticles (NiO NPs) exhibit unique catalytic properties, thermal stability, and interface regulation capabilities, indicating significant potential for improving residual oil recovery. This work emphasizes the green biosynthesis of NiO NPs and their application in oil extraction. It systematically evaluates biosynthesis methods mediated by plants, bacteria, and algae while exploring the effects of biomass and precursor concentrations, as well as reaction and calcination conditions, on the size, morphology, and performance of the resulting products. Furthermore, this paper elucidates the synergistic impact of NiO nanoparticles on enhancing oil recovery mechanisms by modifying wettability, reducing interfacial tension, and catalyzing the viscosity reduction of heavy oil. It also assesses the advancements in research regarding the combined utilization of NiO nanoparticles with traditional techniques, such as heavy oil thermal recovery, chemical flooding, and gas injection. Lastly, the review evaluates the challenges associated with employing NiO nanoparticles in enhanced oil recovery (EOR), encompassing issues like nanoparticle stability, environmental hazards, operational complexities, and cost-effectiveness, among others, while also looking ahead to future research. This review is geared toward fostering the ecofriendly and extensive adoption of NiO nanoparticles and furnishing theoretical groundwork and technical direction for the sustainable advancement of residual oil extraction from formations.
