High Molecular Weight Polyacrylamide for Oilfield Chemical Injection
Oilfield-grade polyacrylamide designed for injection systems that demand strong viscosity, stable flow behavior, and dependable reservoir performance.
This high molecular weight polyacrylamide (HPAM) is tailored for use in oilfield chemical injection programs, including polymer flooding, water control, and produced water conditioning. Its long-chain structure delivers powerful viscosity modification at low dosage and maintains integrity under controlled shear, making it suitable for both onshore and offshore injection facilities.
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
- Polymer flooding for incremental oil recovery.
- Mobility control in waterflood projects.
- Conformance improvement in swept zones.
- Viscosity modification in injection water.
- Produced water flocculation and separation.
- Pipeline flow conditioning and stability.

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.
