Polyacrylamidefactory Why Anionic Polyacrylamide Emulsion Outperforms Powder in EOR
In the evolving field of oilfield chemistry, anionic polyacrylamide emulsion has emerged as a crucial chemical additive for improving Enhanced Oil Recovery (EOR) efficiency. This water-soluble polymer is valued for its excellent rheological properties, thermal stability, and strong interaction with formation minerals, making it ideal for tertiary oil recovery operations in various geological formations.
How It Works in EOR
Anionic polyacrylamide emulsion is typically introduced into oil reservoirs as part of polymer flooding or mobility control techniques. Its function centers around modifying the viscosity of injection water to improve sweep efficiency. This leads to increased contact with residual oil and helps push more oil toward the production well.
Key Mechanisms

Benefit in EOR Process |
|
Mobility Control |
Reduces the mobility ratio of water to oil |
|
Improved Sweep Efficiency |
Enhances the contact area between injected fluid and oil |
|
Conformance Control |
Minimizes water bypassing in high-permeability zones |
|
Salt and Temperature Tolerance |
Enables stable performance in complex reservoir conditions |

Emulsion Form |
Simplifies handling and rapid dissolution |
Unlike powder-based polymers, the emulsion form of anionic polyacrylamide dissolves faster and is easier to pump into the wellbore, which reduces operational time and cost.
Why EOR Needs Smart Chemistry
As conventional oil fields mature, tertiary recovery methods like polymer flooding are essential to maintain productivity. However, the efficiency of this process depends heavily on the quality and performance of the chemical used. A reliable emulsion-grade polyacrylamide provides consistent viscosity control even under variable salinity and temperature levels, making it highly valuable in both sandstone and carbonate reservoirs.
