  • Maximizing Oil Recovery with Polyacrylamide: The Key to Efficient Polymer Flooding in EOR

    Polyacrylamide has become a game-changer in the oil and gas industry, particularly in enhancing oil recovery (EOR) through polymer flooding. EOR techniques are vital for maximizing production from mature or low-yielding reservoirs, and polyacrylamide is at the heart of one of the most effective methods for improving oil extraction rates. But how does this versatile polymer contribute to the effici...

  • The Role of Polyacrylamide Ionic Strength in Papermaking Efficiency

    Polyacrylamide (PAM) is widely recognized for its critical role in improving the papermaking process, particularly as a retention agent, filter aid, and leveling agent. However, one of the most significant factors affecting its performance is its ionic strength, which can drastically influence how polyacrylamide interacts with pulp fibers and enhances the retention of fines. This interaction is no...
