Penetration of a low mobility polymer slug into a reservoir is limited in part by the adsorption of the polymer onto the rock surfaces or entrapment of the polymer in restricted flow channels. However, the behavior of partially hydrolyzed polyacrylamide can depend on both the nature and extent of hydrolysis of the polymer molecule. Laboratory investigations of the viscosity and adsorption characteristics of polyacrylamide hydrolyzed to varying degrees with potassium hydroxide are reported. Sand-pack flow tests indicate that the adsorption of polyacrylamide in porous media decreases with increasing hydrolysis. Resistance factor curves display the effects of viscosity and polymer retention on mobility reduction properties. Information outlined in this study is helpful in showing specific differences in hydrolyzed polyacrylamides that are a function of the degree of hydrolysis and are important in selecting the right polymer for a particular field application.
