Bluwat Chemicals — High-Performance Polymer Solutions for Enhanced Oil Recovery (EOR)

In mature oilfields around the world, conventional waterflooding is no longer enough. As reservoirs age and water cut increases, production becomes inefficient, unstable, and costly. Today, operators need a smarter, more reliable way to push more oil to the surface.

This is why many oilfields turn to Bluwat Chemicals and our high-performance polyacrylamide (PAM/HPAM) polymers for Enhanced Oil Recovery (EOR).

With over 25 years of manufacturing experience, advanced polymer technology, and long-term cooperation with oilfields in Asia, the Middle East, Africa, and South America, Bluwat provides proven polymer flooding solutions designed to boost productivity, reduce water cut, and extend the life of declining wells.

Why Polymer Flooding Works — The Science Behind EOR Polymers

In a typical waterflood, injected water has low viscosity. It bypasses large parts of the reservoir, creates channeling, and leaves significant amounts of oil unrecovered.

Bluwat’s PAM/HPAM polymers change this behavior:

• Increase the viscosity of injected water
• Improve the mobility ratio between water and oil
• Create a more uniform sweep across the reservoir
• Reduce channeling and “finger-like” water breakthroughs
• Push trapped oil toward production wells more effectively

The result is straightforward: more oil recovered, less water produced, and higher long-term well performance.

Benefits of Bluwat PAM for Oilfield EOR

1. Higher Oil Recovery in Mature Fields

Polymer flooding can improve ultimate recovery by 5–18%, depending on reservoir conditions. For many operators, this translates into a substantial volume of incremental oil from fields that are already in late life.

2. Lower Water Cut and Cleaner Production

By controlling the injection profile and improving sweep efficiency, polymer flooding reduces excessive water production and stabilizes output. Oilfields often report:

• Lower water cut at the wellhead
• Higher oil-to-water ratio
• More predictable production curves over time

3. Strong Viscosity and Effective Mobility Control

Bluwat’s HPAM polymers offer:

• Ultra-high molecular weight for strong viscosity building
• Good viscosity retention in the reservoir
• Excellent shear resistance in surface equipment and pipelines
• Stable performance in long-distance injection systems

This ensures that the polymer maintains its effectiveness from the preparation unit, through the injection lines, and into the formation.

4. Tailor-Made Formulations for Difficult Reservoirs

Not all reservoirs are the same, and polymer selection must match specific conditions. Bluwat provides customized solutions for:

• High-temperature reservoirs
• High salinity and high TDS brines
• Low-permeability formations
• Channelized or heterogeneous reservoirs
• Projects with CO₂ presence or complex geochemistry

The product range includes HPAM, salt-resistant PAM, temperature-resistant polymers, and ultra-high molecular weight grades, allowing operators to select the most appropriate formulation for their EOR project.

5. Reliable Quality and Scalable Supply

As a factory-direct manufacturer, Bluwat Chemicals ensures:

• Consistent product quality from batch to batch
• Competitive and stable pricing
• Fast and flexible delivery
• Long-term supply security for large-scale projects

Our polymers are used in national oil companies, independent operators, and EOR pilot projects across multiple regions.
