New features of polymer rheology in porous media were observed when hydrolyzed polyacrylamide (HPAM) solutions were flowed through sandstone, gravel packs, and glass bead packs at high rates. Independent measurement of elongational viscosity (eta,/sub e/) with a ductless siphon technique demonstrates that the enhanced resistance seen at high flow rates is not directly proportional to eta/sub e/. Furthermore, permeability trends in resistance factor and mechanical degradation when plotted against strain rate are discussed. When these results are translated to field flow rates and geometries they indicate that HPAM solutions can be injected at reasonable injection pressures with minimal viscosity losses provided that perforated completions are designed with either sufficient perforation density or perforation size.
