The oil and gas industry continuously seeks methods to maximize hydrocarbon extraction from existing reservoirs. Enhanced Oil Recovery (EOR) techniques are vital for this, and Polyacrylamide (PAM) is a cornerstone chemical in many EOR processes. As a leading Polyacrylamide manufacturer in China, we supply high-grade PAM crucial for improving oil production efficiency and reservoir management.

Polyacrylamide's Function in Enhanced Oil Recovery (EOR):

PAM's effectiveness in EOR stems from its ability to modify fluid properties within the reservoir. Its primary functions include:

• Viscosity Modifier: When injected into the reservoir, PAM increases the viscosity of the injected water. This improved viscosity helps to sweep more oil towards the production wells, displacing oil that would otherwise be left behind by conventional water flooding. The high molecular weight of PAM is key to achieving this viscosity enhancement.
• Friction Reducer: During hydraulic fracturing operations, PAM is added to fracturing fluids to reduce friction between the fluid and the pipeline walls, as well as within the rock fractures. This reduction in friction allows for higher injection rates with lower pressure, leading to more efficient fracturing and improved well productivity.
• Profile Control & Water Plugging: PAM can be used to selectively block high-permeability zones in a reservoir, diverting injected water into less permeable areas and improving sweep efficiency for oil recovery.

Selecting the Right Polyacrylamide for EOR:

EOR applications often involve harsh reservoir conditions, including high temperatures, high salinity, and shear forces. Therefore, the selection of PAM is critical:

• Molecular Weight: Higher molecular weight PAM generally provides better viscosity and drag reduction.
• Ionic Charge: Anionic PAM is commonly used, especially in lower salinity conditions, for its excellent viscosity-building properties. In high salinity or high divalent ion environments, more specialized or modified PAM might be required.
• Thermal and Shear Stability: PAM used in EOR must withstand reservoir conditions without significant degradation.
