The oil and gas industry is a major consumer of advanced chemical technologies, and Polyacrylamide (PAM) is among the most versatile and impactful. Its unique properties make it indispensable for a range of applications, from improving oil extraction efficiency to optimizing the performance of drilling fluids. As a leading manufacturer and supplier, we provide specialized PAM grades tailored for the demanding conditions of the oilfield.

PAM's utility in the oilfield stems from its ability to modify fluid properties significantly. Its high molecular weight and controllable charge allow it to act as a viscosifier, friction reducer, and flocculant, all crucial for efficient and cost-effective oil and gas exploration and production.

Enhanced Oil Recovery (EOR)

One of the most significant applications of PAM in the oilfield is in Enhanced Oil Recovery (EOR) processes, particularly polymer flooding. In conventional waterflooding, a significant amount of oil often remains trapped in the reservoir pores. By injecting polymer solutions, the viscosity of the injected water is increased. This improves the sweep efficiency, pushing more oil towards the production wells and significantly boosting recovery rates. Anionic PAM, particularly partially hydrolyzed polyacrylamide (HPAM), is commonly used due to its excellent stability in reservoir conditions and its ability to provide the required viscosity.

Friction Reduction in Hydraulic Fracturing

In high-volume hydraulic fracturing (HVHF), PAM is widely used as a friction reducer. During the pumping of fracturing fluids, high shear rates and turbulent flow can lead to significant frictional pressure losses, requiring more energy and increasing operational costs. PAM molecules, when injected into the fluid, align and dampen these turbulent eddies, dramatically reducing friction. This allows for higher pumping rates and shallower wellbore pressures, making the fracturing process more efficient and economical. Anionic PAM is typically favored for its performance in freshwater systems.

Drilling Fluid Additives

PAM also serves as a vital additive in drilling fluids. It functions as a viscosifier, a shale inhibitor, and a flocculant for solids control. Its ability to increase fluid viscosity helps suspend drill cuttings and carry them to the surface. As a shale inhibitor, it prevents clay hydration and swelling, which can cause wellbore instability. In terms of solids control, PAM helps flocculate fine drill solids, improving their removal by solids control equipment, thus maintaining the drilling fluid's rheological properties and performance.

Selection and Sourcing for the Oilfield

The harsh conditions in oilfield applications—including high temperatures, high salinity, high shear rates, and specific reservoir chemistries—demand specialized PAM products. Factors like molecular weight, degree of hydrolysis, and tolerance to divalent cations are critical for optimal performance. As a dedicated manufacturer, we understand these requirements and offer tailored solutions, including salt-tolerant and thermally stable PAM grades.
