SUPPORTING INFORMATION for Rheology of polyacrylamide-based fluids and its impact on proppant transport in hydraulic fractures

Rheological data for the solutions prepared by gentle mixing at 200 rps; Mean size, mean density and particle size distributions of the 16/20 and 30/50 ForeProp ceramic proppants; Particle settling velocity and experimental-to-calculated settling velocity ratio against concentration of polyacrylamide in linear scale; Numerical simulations of particle settling in polyacrylamide-based fluids; Accuracy of the proppant settling model, based on "smart" Stokes law
