| Summary: | This research investigates the influence of various concentrations of BaTiO<sub>3</sub> nanofluid on adsorption energy and improved oil recovery. BaTiO<sub>3</sub> nanoparticles were successfully synthesized using a Sol-gel approach at temperatures of 400 °C, 500 °C, 800 °C, and 1000 °C and characterized for their structural and morphological properties and interfacial tension (IFT)/Wettability measurement. The study focuses on using ferroelectric nanofluid in combination with an electromagnetic field to enhance oil recovery mechanisms. Three concentrations of BaTiO<sub>3</sub> nanofluid were prepared, and their effects on pressure and recovery factors were examined. The results demonstrate that BaTiO<sub>3</sub> nanofluids increase the reservoir fluid’s ionic conductivity, leading to environmental polarization. Applying BaTiO<sub>3</sub> nanofluid on glass bead samples resulted in a significant 42.15% increase in the recovery factor at a 0.3% concentration in various measurements, including interfacial tension, core-flooding, and wettability. The nanofluid caused a reduction in interfacial tension and a shift in wettability from oil-wet to water-wet. The higher adsorption energy of the nanofluid corresponded to more significant oil recovery. The optimal concentration for maximum adsorption energy (−2.566331 × 10<sup>4</sup>) and oil recovery (22.5%) was 0.3wt%. At 0.1% concentration, the IFT value was 0.023 mN/m, at 0.3% concentration the IFT was 0.017 mN/m and at 0.5% concentration IFT value was 0.032 mN/m. The contact angle of the brine with the oil was 89.39% compared to the contact angle of 0.1%, 0.3%, and 0.5% which were 64.25%, 10.57%, and 44.63%, respectively. It was revealed from the result that 0.3% of nanofluid decreased the contact angle from 89.39% to 10.57 at a 0.3% concentration of BaTiO<sub>3</sub> nanofluid. This shows that the wettability of the rock surface changed from oil-wet to water-wet with the novel application of BaTiO<sub>3</sub> nanoparticles. This improvement in recovery can be attributed to the modification of wettability and reduction of interfacial tension. |
