Anionic PAM for Oilfield Polymer Flooding
CAS Number: 9003-01-4
Ultra-high molecular weight partially hydrolyzed polyacrylamide (HPAM) with MW 12–25 million Da, engineered for enhanced oil recovery (EOR) polymer flooding applications. The 25–35% hydrolysis degree provides optimal viscoelastic properties to increase sweep efficiency and reduce water-oil mobility ratio in reservoir conditions.

- Chemical EOR — ASP (alkali-surfactant-polymer) flooding
- Reservoir conformance control and profile modification
- High water-cut well production improvement
- Oilfield injection water viscosity adjustment
Key Features
- Ultra-high MW (up to 25 million Da) for maximum viscosity build at low dosage
- 25–35% hydrolysis degree balances viscosity, salt tolerance, and thermal stability
- Meets SY/T 5862 oilfield polymer quality standard for EOR applications
- Dissolves uniformly in saline injection water with minimal shear degradation
- Proven performance in tertiary oil recovery to boost recovery factor by 5–15%
