The global demand for energy continues to drive innovation in oil and gas extraction. Enhanced Oil Recovery (EOR) techniques are vital for maximizing hydrocarbon yields from mature reservoirs. Among the key chemical agents employed in EOR, Polyacrylamide (PAM) stands out for its ability to significantly improve oil recovery rates. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-performance PAM tailored for the stringent requirements of the oil and gas industry.

In EOR, particularly polymer flooding, PAM is injected into the reservoir to increase the viscosity of the injected water. This enhanced viscosity has several critical effects: Firstly, it improves the microscopic sweep efficiency by reducing the mobility ratio between the injected water and the oil. A higher viscosity injected fluid is less likely to bypass the oil trapped in the porous rock formations. Secondly, it improves the macroscopic sweep efficiency by reducing water channeling through the more permeable zones of the reservoir, thus directing the injected fluid towards more oil-rich areas. This targeted displacement is crucial for extracting residual oil that would otherwise be left behind.

The specific characteristics of PAM used in EOR are important. These polymers typically have very high molecular weights and are often partially hydrolyzed, giving them anionic properties. These properties are optimized to provide the necessary viscosity increase while remaining stable under reservoir conditions, which can include high temperatures and salinities. The selection of the right PAM is critical; factors such as shear stability, salt tolerance, and thermal stability are paramount. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of PAM products engineered to meet these demanding oil recovery polyacrylamide specifications.

Beyond viscosity modification, PAM can also be used for other EOR-related applications, such as profile control and water plugging. In these roles, PAM is used to selectively block high-permeability zones or fractures that allow injected water to bypass oil, thereby redirecting the flow to more productive zones. This precise control over fluid movement within the reservoir is essential for optimizing the overall recovery process.

The benefits of using PAM in EOR are substantial. It can lead to a significant increase in the recovery factor, bringing previously uneconomical reserves into production. This translates directly into increased oil production and improved profitability for exploration and production companies. The detailed pam flocculant applications extend to improving the efficiency of operations and extending the productive life of mature oil fields.
