| Abstract: |
| In the present study, we synthesized γ-Al2O3 nanostructures with spherical, rod-shaped, and plate-like morphologies and characterized them using the X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) analyses. The XRD results showed that that the synthesized samples had a gamma structure with no impurity. Also, FESEM images revealed that these morphologies have been synthesized at neutral, acidic, and alkaline conditions, respectively. A sustained nanofluid with an aqueous base was produced using these nanoparticles. To evaluate the performance of gamma-alumina nanostructures on the heavy oil recovery, some viscosity tests followed by initial and enhanced recovery tests at the simulated porous media with the temperature of 80℃ were performed. Adding this aqua-based nanofluid containing γ-Al2O3 nanoparticles to heavy oil and was found effective in reducing the heavy oil viscosity. According to the results of the viscosity tests conducted in this work, it was identified that nanoparticle with plate-like morphology at a concentration of 0.25 wt.% show the largest reduction in the viscosity of heavy oil sample from 1099 cp to 698 cp (a 36% reduction); leading to a 4% increase in enhanced oil recovery. |
