In the global pursuit of maximizing hydrocarbon extraction from mature oil fields, Enhanced Oil Recovery (EOR) techniques are paramount. Among the most established and cost-effective EOR methods is polymer flooding, where water-soluble polymers like polyacrylamide (PAM) are injected into the reservoir to improve sweep efficiency. As a leading manufacturer and supplier of specialty organic chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides high-performance polyacrylamide specifically designed for the demanding conditions of EOR operations.

Understanding Polymer Flooding with Polyacrylamide

The fundamental principle behind polymer flooding is to increase the viscosity of the injected water. In conventional waterflooding, lower-viscosity water tends to bypass oil in the reservoir, leading to poor sweep efficiency. By injecting polyacrylamide solutions, the viscosity of the injected water is significantly increased. This viscous water then pushes the oil more effectively towards production wells, mobilizing residual oil that would otherwise remain trapped in the reservoir rock pores.

Key Benefits of Using Polyacrylamide in EOR

Polyacrylamide offers several critical advantages for EOR projects:

  • Improved Sweep Efficiency: The primary benefit is the increased mobility ratio, leading to better displacement of oil from the porous media.
  • Reduced Water Channeling: PAM solutions can selectively reduce permeability in high-permeability zones, preventing injected water from channeling directly to production wells and ensuring more uniform oil displacement.
  • Shear Stability: For EOR applications, the polyacrylamide must maintain its molecular integrity and viscosity-enhancing properties even under the high shear forces encountered during injection and flow through reservoir rock. We offer specialized polyacrylamide grades with excellent shear stability.
  • Salinity and Temperature Tolerance: Reservoir conditions often involve high salinity and elevated temperatures. Our EOR-grade polyacrylamides are engineered to perform optimally under these challenging conditions, ensuring consistent viscosity.

Selecting Polyacrylamide for Oilfield Applications

When considering polyacrylamide for your EOR projects, it is essential to select products with specifications suitable for reservoir conditions. This includes molecular weight, degree of hydrolysis, and specific formulations designed for oilfield use. We offer a range of polyacrylamide products, including partially hydrolyzed polyacrylamide (PHPA), which is widely used in EOR. If you are looking to buy polyacrylamide for oil recovery, understanding the reservoir characteristics will help us recommend the most effective product.
