For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.

The most common polymer for EOR projects is partially hydrolyzed polyacrylamide (HPAM). Since 1970s, continuous efforts have been spent on understanding the factors that influence the viscosity behavior of HPAM. It was discovered that shearing, heat, divalent ions and monovalent ions all have negative impacts on polymer viscosity.
