Surfactant mixture in partially hydrolyzed polyacrylamide polymer for enhanced oil recovery

Chemical EOR has won significant interest in the oil and gas industry over decades. The use of nanoparticles, alkaline, foam and most importantly polymers and surfactants, have been widely explored. Surfactants have achieved great interest because it can reduce IFT and subsequently improve oil recov...
