Abstract

Although polymer flooding is an efficient chemical enhanced oil recovery (CEOR) method, the poor thermal and salinity stability of commonly used partially hydrolysed polyacrylamide (HPAM) hinders its implementation in reservoirs with extremely high-temperature and high-salinity (HTHS) conditions. Hence, the synthesis of environmentally sustainable polymers able to maintain stability under harsh reservoir conditions is of significant research interest for enhanced oil recovery (EOR) applications.
