Partially hydrolyzed polyacrylamide apparent viscosity in porous media enhancement by silica dioxide nanoparticles under high temperature and high salinity

Polymer flooding effectiveness is hindered by high temperature and high salinity due to polymer degradation. Researchers proposed the addition of nanoparticles to improve polymer stability to withstand reservoir conditions. Therefore, extensive rheological study and flooding test of partially hydrol...
