How Polyacrylamide Helped Unlock More Oil from a Mature Reservoir

The Challenge: Declining Production in a Mature Oilfield

An oilfield operator in the Middle East was facing a common challenge. After years of conventional water flooding, production had begun to decline significantly. Large volumes of injected water were bypassing oil-rich zones and flowing through high-permeability channels, leaving valuable crude trapped underground.

The operator needed a solution that could improve sweep efficiency without requiring major infrastructure investments.

The Solution: Polyacrylamide Polymer Flooding

After extensive evaluation, the engineering team implemented a polymer flooding program using high-molecular-weight Polyacrylamide.

When dissolved in injection water, PAM increased the water’s viscosity, allowing it to move more uniformly through the reservoir. Instead of flowing only through the easiest pathways, the treated water pushed deeper into oil-bearing formations and mobilized previously unrecovered crude oil.

Within months of implementation, the operator observed:

• Improved water injection profile
• Reduced water channeling
• Better sweep efficiency across the reservoir
• Increased oil production rates
• Enhanced ultimate recovery factor

The project demonstrated how PAM can significantly improve the economics of mature oilfields while extending reservoir life.

Why Oilfield Operators Choose Polyacrylamide

Polyacrylamide is widely used in Enhanced Oil Recovery (EOR) operations because it offers:

✔ Higher oil recovery rates
✔ Improved mobility control
✔ Reduced water production issues
✔ Cost-effective reservoir management
✔ Compatibility with various reservoir conditions
✔ Easy preparation and field application

Today, PAM plays a critical role in oilfields across the Middle East, Africa, North America, Central Asia, and South America, helping operators maximize production while controlling operating costs.
