Product Profile
The product is supplied as a granular, free-flowing powder that rapidly hydrates in fresh water and compatible brines. When properly prepared, it forms a clear to slightly opalescent solution with predictable rheology, suitable for direct feed into chemical injection pumps or polymer flooding skids.
Key Functional Characteristics
- High molecular weight for strong thickening and mobility control at low polymer concentrations.
- Good injectivity when dosage and water quality are correctly engineered.
- Stable viscosity over time under typical storage and injection conditions.
- Capable of supporting EOR polymer floods, water blocking treatments, and produced water clarification.
Typical Use Cases
Enhanced Oil Recovery
- Polymer flooding for incremental oil recovery.
- Mobility control in waterflood projects.
- Conformance improvement in swept zones.
Water & Flow Management
- Viscosity modification in injection water.
- Produced water flocculation and separation.
- Pipeline flow conditioning and stability.
Reservoir and water-chemistry screening are essential steps before full-scale deployment. Pilot tests help optimize concentration, injection rate, and compatibility.

Preparation & Injection
Proper solution preparation is critical to obtain the designed viscosity and to avoid gel formation or incomplete hydration.
Engineering Considerations
- Assess hardness, salinity, and dissolved solids in injection or formation water.
- Evaluate polymer aging and viscosity retention at reservoir temperature.
- Monitor injectivity, pressure behavior, and production response over time.
- Apply filtration and low-shear equipment to protect polymer integrity.
