The oil and gas industry relies heavily on specialized chemicals to optimize extraction and production processes. Among these, polyacrylamide (PAM) stands out as a highly effective polymer utilized in two key areas: Enhanced Oil Recovery (EOR) and friction reduction in hydraulic fracturing fluids. As a dedicated manufacturer and supplier of high-performance polyacrylamide, we provide critical insights into its application and benefits for oilfield operations.

Polyacrylamide in Enhanced Oil Recovery (EOR)

In EOR, PAM is primarily used as a viscosity modifier. When injected into oil reservoirs, PAM increases the viscosity of the injection fluid (water or brine). This improved viscosity helps to sweep trapped oil more effectively from the porous rock formations towards production wells. By enhancing the sweep efficiency, PAM plays a vital role in increasing the overall recovery of oil from mature fields. Key considerations for EOR applications include:

  • High Molecular Weight: EOR applications typically demand very high molecular weight PAM (often exceeding 10 million Da) to achieve the necessary viscosity increase.
  • Thermal and Chemical Stability: PAM used in EOR must withstand the high temperatures and salinity found in many reservoirs. Selecting polymers with good stability is crucial for long-term effectiveness.
  • Resistance to Shearing: The polymer must maintain its structure under the shear forces encountered during injection to provide sustained viscosity.

As a trusted polyacrylamide manufacturer, we offer specialized EOR-grade PAM that meets these demanding requirements. Understanding the reservoir conditions allows us to recommend the most suitable product when you buy polyacrylamide for your EOR projects.

Polyacrylamide as a Friction Reducer

In hydraulic fracturing, the rapid pumping of large volumes of fluid requires efficient energy usage. PAM polymers act as highly effective friction reducers, significantly lowering the pressure drop and pumping energy required. This is achieved by altering the turbulent flow characteristics within the pipelines and fractures, making the fluid flow smoother. This application is critical for the economic viability of unconventional resource development.

Factors influencing PAM selection for friction reduction include:

  • Molecular Weight and Charge: While high molecular weight is beneficial, the optimal charge type (anionic or cationic) can depend on water salinity and compatibility with other fracturing fluid components. Anionic PAM is often preferred in lower salinity freshwater systems.
  • Concentration: Effective friction reduction is typically achieved at very low concentrations (ppm levels).
  • Shear Stability: The polymer must maintain its efficacy under high shear rates encountered during pumping.
