Polyacrylamide (PAM) solutions are extensively used as chemical additives or Processing aids in the manufacturing of paper and paperboard products. In addition, they have been widely used in enhanced oil recovery. In our paper, an experimental work has been carried out to provide a complete and comprehensive study of the rheological properties of PAM solutions using Brookfield viscometer DV-II. The concentrations of PAM in the tested solutions ranged by weight from 1000 to 5000 ppm. The findings resulted in several conclusions regarding the rheological properties of PAM solutions. They have shown a strong shear thinning behavior for all concentrations. Rheological characteristics of aqueous PAM solutions with shear rate ranged between 1.29 s-l and 64.5 s-1 are investigated. A new proposed correlation for the viscosity of PAM solution as a function of shear rate and concentration has been suggested. The proposed correlation was found to be good fitting with the experimental data.
