Abstract

Abstract: The rheological behavior of ASP ( Alkaline -Polymer - Surfactant ) solutions flowing through porous media was investigated with core - flood
tests. The results indicate that the ASP solutions in porous media exhibit rheological characteristics with shear thinning at low shear rate and shear thickening a high shear rate. The critical shear rate decreases with increased concentration of polymer and with de-creased concentrations of both alkaline and surfac-tant.
