The oil and gas industry is constantly seeking innovative methods to maximize hydrocarbon recovery from mature fields. Enhanced Oil Recovery (EOR) techniques are crucial for this, and among the most effective chemical EOR methods is polymer flooding, where polyacrylamide (PAM) plays a central role. As a specialized chemical manufacturer and supplier, we provide high-performance PAM designed to meet the rigorous demands of the petroleum sector.

Polyacrylamide's effectiveness in EOR stems from its unique rheological properties, primarily its ability to significantly increase the viscosity of injection water. In traditional water flooding, water injected into the reservoir can bypass oil due to unfavorable mobility ratios – meaning the water flows more easily through the porous rock than the oil does. This leads to inefficient sweep of the oil-bearing formations.

By dissolving polyacrylamide in the injection water, the viscosity of the water is dramatically increased. This viscous water front then has a mobility ratio closer to that of the oil, leading to a more effective sweep of the reservoir. The PAM-laden water pushes the oil more uniformly towards production wells, recovering trapped oil that would otherwise be left behind. This process is often referred to as polymer flooding or viscosity modification.

Key benefits of using polyacrylamide in EOR include:

  • Improved Sweep Efficiency: By controlling the mobility ratio, PAM ensures more effective displacement of oil from the reservoir rock.
  • Reduced Water Channeling: PAM helps to reduce the tendency for injected water to channel through high-permeability streaks, ensuring more uniform sweep.
  • Enhanced Oil Recovery (EOR): Ultimately, this leads to a significant increase in the amount of oil recovered from a reservoir.
  • Versatility: Different grades of PAM, such as partially hydrolyzed polyacrylamide (PHPA), are tailored for specific reservoir conditions (temperature, salinity, shear rates) to optimize performance and stability.

The selection of the appropriate polyacrylamide grade for EOR is critical and depends on several reservoir parameters, including temperature, shear rate, salinity, and the rock's mineralogy. High-temperature or high-salinity environments may require specialized grades of PAM or modified polymers to maintain their viscosity-enhancing properties and prevent degradation. Our company offers a range of EOR-grade polyacrylamides and can assist with product selection based on detailed reservoir data.
