Viscosity of partially hydrolyzed polyacrylamide under

Polymer flooding is the most successful chemical method to enhance oil recovery. This technique has achieved large-scale field application in China. Polymer flooding is also being tested in several heavy oil fields. For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery.

Rheological Properties of Partially Hydrolyzed

This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO 2) nanoparticles (NPs).Novel aqueous HPAM-based SiO 2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times.
