Enhanced oil recovery from sandstone reservoir using cationic hyperbranched polyamidoamine dendrimer surfactant flooding under real reservoir conditions

Abstract This study investigates the application of a synthesized cationic hyperbranched polyamidoamine (PAMAM) dendrimer surfactant (G2-C12) as a novel chemical agent for enhanced oil recovery (EOR) in sandstone reservoirs under realistic high-salinity and high-temperature conditions. The dendrimer...
