"Experimental Investigation of the Effect of Different Process Variables on the Viscosity of Sulfonated Polyacrylamide Copolymers," Journal of Petroleum Exploration and Production Technology, Vol. 7, pp. 87-101. Description: Results of an Experiment relating Viscosity (mPa s) to Polymer Concentration (100, 1000, 2500, 3500, 5000 ppm) and Shear Rate (10, 31.6228, 100.776, 316.228, 1000 1/sec) Authors fit as 2-Way ANOVA (1 rep/cell). Appears it could be run as regression on log scale (particularly Xs) Variables SampleID PolymerConc ShearRate Viscosity
