Full factorial analysis with ANOVA and physiochemical investigation of ZnO/Al2O3 with pure bore at low salinity to improve oil recovery

The nanotechnology possesses vast application for enhanced oil recovery and that has increased significantly on a global scale, and nanofluid has been broadly employed in reservoirs to boost the hydrocarbons recovery. An laboratorial examination was conducted with salinity (NaCl 2.5 wt%) to observe the adding together that zinc oxide (ZnO) and aluminum oxide (Al₂O₃) with nanofluid formed by pure bore may provide to enhance the oil recovery. To fully understand the nanofluid, a laboratory analysis was conducted utilizing FTIR, EDX and XRD of ZnO and Al₂O₃. To gain insight into structure, the nanofluid microstructure was examined. Under laboratory settings, the effects of pure bore concentration (0.30–0.50 wt%) and Al₂O₃ and ZnO concentrations (0.05–0.40 wt%) in brine solution (NaCl 2.5 wt%) were examined. SEM, EDX, FTIR and XRD were used to examine the value addition with Al₂O₃ and ZnO bring to the nanofluid. The analytical inquiry aided in the analysis of the nanofluid’s microstructure. Additionally, the effect of salt on viscosity was explored. The optimum/critical concentrations of pure bore 0.40 wt% and Al₂O₃ 0.30 wt% were reached at salinity conditions (NaCl 2.5 wt%). Statistical analysis with ANOVA analysis and full factorial design were used to validate the results, and it was revealed that the nanofluid prepared employing pure bore (0.40 wt%) and ZnO (0.30 wt%) with salinity NaCl (2.5 wt%) is stable and useful for enhancing oil production as contrast to nanofluid that was prepared with Al₂O₃ (0.30 wt%) under same polymer and saline concentration.
