The global demand for energy necessitates efficient extraction of oil and gas resources. Enhanced Oil Recovery (EOR) techniques are crucial for maximizing yield from existing reservoirs, and Polyacrylamide (PAM) plays a pivotal role in these advanced methods. NINGBO INNO PHARMCHEM CO., LTD. is at the forefront of supplying high-quality PAM, understanding its significant impact on the petroleum industry.

Within the petroleum sector, PAM in the petroleum industry is recognized for its dual functionality. Firstly, it acts as a highly effective thickener for drilling fluids. These fluids are essential for lubricating drill bits, removing rock cuttings, and stabilizing the borehole walls. By increasing the viscosity of the drilling fluid, PAM ensures that cuttings are efficiently transported to the surface, preventing accumulation and maintaining drilling stability. This contributes to safer and more productive drilling operations.

Secondly, and perhaps more critically for long-term production, PAM serves as a key component in polymer flooding, a common EOR technique. In this process, PAM is injected into the reservoir in a water solution. Its high molecular weight and viscosity significantly increase the viscosity of the injected water. This leads to several beneficial outcomes:

  • Improved Sweep Efficiency: The higher viscosity of the polymer solution allows it to push oil more effectively through the reservoir's porous rock formations, reaching areas that might be bypassed by lower-viscosity water. This is often referred to as improving the sweep efficiency of the oil displacement process.
  • Reduced Water Fingering: In reservoirs where water is injected, it can sometimes channel through the most permeable zones, bypassing much of the oil (a phenomenon known as water fingering). The increased viscosity provided by PAM suppresses this fingering, ensuring more uniform contact with the oil.
  • Enhanced Oil Recovery: By improving sweep efficiency and mitigating water fingering, polymer flooding with PAM can significantly increase the overall recovery of oil from a reservoir, often recovering an additional 5-20% of the original oil in place.

NINGBO INNO PHARMCHEM CO., LTD. supplies various grades of PAM tailored for specific reservoir conditions, including different molecular weights and ionic charges, to optimize performance. Understanding the rheological properties and shear stability of PAM is critical for successful implementation in EOR projects. The selection of the right polyacrylamide for oilfield applications ensures cost-effectiveness and maximizes the return on investment.

The efficacy of PAM in enhancing oil recovery is well-documented, making it a go-to chemical for operators seeking to maximize their production assets. As the industry continues to seek more efficient extraction methods, the role of Polyacrylamide will remain indispensable. NINGBO INNO PHARMCHEM CO., LTD. is committed to providing the innovative chemical solutions that drive success in the demanding energy sector.
