Anionic polyacrylamide (APAM) is commonly used for water plugging in various applications, particularly in the oil and gas industry. The main application for anionic polyacrylamide in water plugging is in Enhanced Oil Recovery (EOR) processes. Here are the key aspects of its application:

1. Water Shutoff in Oil Wells: Anionic polyacrylamide is employed as a water-soluble polymer in oil reservoirs to reduce water production and enhance oil recovery. In the context of water plugging, it is used to selectively block or reduce the permeability of water-bearing zones within oil reservoirs. This helps divert injected water toward the less permeable zones, forcing the water to sweep oil from those areas and improve overall recovery efficiency.

2. Profile Modification: Anionic polyacrylamide is often used for profile modification in water injection wells. By altering the permeability profile along the wellbore, it helps to control the injection profile of water, ensuring that water is injected more uniformly across the reservoir. This can improve sweep efficiency and reduce the risk of early water breakthrough.

3. Water Control in Fractured Reservoirs: In reservoirs with complex geological structures, such as fractured formations, anionic polyacrylamide is used to control water movement and channeling. It can be applied to reduce water permeability in certain zones, preventing the preferential flow of water through fractures and improving oil displacement.

4. Gel Plugging: Anionic polyacrylamide is also used in the formulation of gel plugging systems. These gels can be injected into the reservoir to selectively plug high-permeability zones, diverting injected water to less permeable areas and improving sweep efficiency.

The goal of using anionic polyacrylamide in water plugging applications is to enhance the effectiveness of water injection processes in oil reservoirs, leading to increased oil recovery rates. The polymer's ability to modify the reservoir's fluid flow characteristics makes it a valuable tool in the field of Enhanced Oil Recovery.
