The oil and gas industry constantly seeks innovative solutions to maximize hydrocarbon extraction and optimize operational efficiency. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced polymer technologies, with Polyacrylamide (PAM), especially Anionic Polyacrylamide (APAM), playing a pivotal role. This article explores the critical applications of PAM in oilfield operations, focusing on its contributions to Enhanced Oil Recovery (EOR) and hydraulic fracturing.

In the realm of Enhanced Oil Recovery (EOR), maintaining reservoir pressure and improving the sweep efficiency of injected fluids are paramount. Polymer flooding, a key EOR technique, utilizes high molecular weight polymers like APAM to increase the viscosity of the injected water. This increased viscosity reduces the mobility ratio between water and oil, allowing the water to displace more oil from the reservoir rock and push it towards the production wells. APAM's robust molecular structure ensures it can withstand the harsh downhole conditions, including elevated temperatures and salinities, thereby providing sustained viscosity enhancement and boosting ultimate oil recovery rates. The effectiveness of anionic polyacrylamide polymer flocculant in this application is well-documented, offering a cost-effective method to unlock additional reserves.

Hydraulic fracturing, another vital process in unconventional oil and gas extraction, relies heavily on the properties of specific chemical additives. APAM is widely used as a friction reducer in fracturing fluids. During the high-pressure pumping of fracturing fluids downhole and through the formation, significant frictional pressure losses occur, requiring more energy and potentially damaging equipment. APAM molecules, when dissolved in water, align with the flow, smoothing out turbulent eddies and substantially reducing this frictional drag. This allows for higher pumping rates with lower pressure, enabling deeper and more effective fracturing of the reservoir rock, which is crucial for unlocking tight gas and oil formations. The ability to tailor APAM's molecular weight and charge density makes it adaptable to various fracturing fluid formulations and reservoir conditions.

Beyond these primary applications, PAM also finds use in drilling fluids, acting as a viscosity modifier and fluid loss control agent. It helps stabilize the borehole, prevent formation damage, and ensure the efficient removal of drill cuttings. The performance benefits of using APAM in oilfield operations are clear: increased oil recovery, improved fracturing efficiency, reduced operational costs due to lower energy consumption, and enhanced well productivity.
