Effect of Polyacrylamide with ZnO Nano Aqueous Solution on the Chemical Flooding Method with Enhanced Oil Recovery (EOR) – An Experimental and Modelling Study

This work studied the effect of polyacrylamide (PAM) with ZnO nanoparticles (NPs) solution on the recovery of crude oil in tertiary stage. Shear viscosity due to shear rate and salt concentration, also shear stress with different shear rates were tested. Core flooding test used to check the ratio of oil produced from Core as porous media. Ansys-Fluent 16.1 by program based on finite volume with the help of experimental data was used to visualize the interphase between injected fluid and oil in porous media. The results show that the shear viscosity decreases and shear stress increases with the ZnO NPs increasing. Non-Newtonian flow and shear thinning phenomena dominate the viscosity curve. 1000ppm PAM with 0.005%ZnO/brine water give 80.32%oil production, low interfacial tension and uniform interaction in Oil Volume. Fraction between injected solution and displacement fluid form Core by Ansys.
