  • HPAM Hydrolyzed Polyacrylamide for Bahrain

    Biodegradation of hydrolyzed polyacrylamide by the Hydrolyzed polyacrylamide (HPAM) is widely used to EOR in many oilfields, and it is generally accepted as a nontoxic polymer. However, under certain physical or chemical conditions, it may degrade and produce acrylamide (AM), which exhibits toxicity to nervous system and damages human health seriously (Rayburn and Friedman, 2010).
