“…Physical synthesis of nanoparticles requires a lot of energy, and the yield is low; chemical methods need less energy in the process of synthesizing nanoparticles, and the formed particles are homogeneous and have a high shape accuracy. However, the use of various hazardous chemicals can seriously pollute the environment due to their carcinogenicity, genotoxicity, and cytotoxicity. − The biological methods utilize biomaterials-mediated, end-capped, encapsulated, or microbial self-produced nanoparticles . Similarly, the biological synthesis of nanoparticles is an economical, efficient, and ecofriendly strategy. , The synthesized nanoparticles do not contain toxic chemical pollutants, and the time required for nanoparticle biosynthesis is much less in contrast to some of the other physicochemical approaches for synthesis .…”

Nanoparticles (NPs) have attracted great attention in the tertiary oil recovery process due to their unique properties. As an economical and efficient green synthesis method, biosynthesized nanoparticles have the advantages of low toxicity, fast preparation, and high yield. In this study, with the theme of biotechnology, for the first time, the bio-nanoparticles reduced by iron-reducing bacteria were compounded with the biosurfactant produced by Bacillus to form a stable bio-nano flooding system, revealing the oil flooding mechanism and enhanced oil recovery (EOR) potential of the bio-nano flooding system. The interfacial properties of the bio-nano-oil displacement system were studied by interfacial tension and wettability change experiments. The enhanced oil recovery potential of the bio-nano-oil displacement agent was measured by microscopic oil displacement experiments and core flooding experiments. The bio-nano-oil displacement system with different nanoparticle concentrations can form a stable dispersion system. The oil–water interfacial tension and contact angle decreased with the increase in concentration of the bio-nano flooding system, which also has a high salt tolerance. Microscopic oil displacement experiments proved the efficient oil displacement of the bio-nano-oil displacement system and revealed its main oil displacement mechanism. The effects of concentration and temperature on the recovery of the nano-biological flooding system were investigated by core displacement experiments. The results showed that the recovery rate increased from 4.53 to 15.26% with the increase of the concentration of the system. The optimum experimental temperature was 60 °C, and the maximum recovery rate was 15.63%.
