Temperature-Resistant HPAM Polyacrylamide for Thermal EOR
High-temperature HPAM engineered for steam flooding, thermal recovery, SAGD injection, and harsh reservoir conditions.
This temperature-resistant HPAM polyacrylamide is specifically developed for thermal Enhanced Oil Recovery (EOR) environments where elevated temperatures and thermal stresses typically degrade conventional polymers. Its reinforced molecular architecture allows it to maintain viscosity, elasticity, and solution stability under high-temperature conditions, supporting mobility control and improved oil displacement in steam-assisted processes.
Product Overview
Unlike standard HPAM, this temperature-resistant grade incorporates thermally stable linkages and optimized hydrolysis levels to mitigate viscosity loss at elevated temperatures. It is designed for use in reservoir environments where fluids may reach 80–180°C, such as steam flooding or cyclical thermal recovery.
Key Performance Advantages
- Maintains viscosity at high temperatures (up to 120–150°C depending on grade).
- Resistant to thermal degradation and hydrolysis-induced viscosity collapse.
- Compatible with moderate salinity and mineralized injection waters.
- Improved sweep efficiency in thermal recovery operations.
- Enhanced molecular resilience during mechanical and thermal stress.
Applications in Thermal EOR
- Steam flooding — improves vertical and areal conformance.
- SAGD (Steam Assisted Gravity Drainage) chemical-assisted mobility control.
- Cyclic steam stimulation for enhanced viscosity modification.
- High-temperature polymer flooding in deeper or geothermal-influenced reservoirs.
- Mobility ratio correction where steam front destabilizes traditional water-phase control.
Thermal-Resistant Functionality
Temperature-resistant HPAM is engineered to withstand hydrolysis and free-radical degradation that typically occur at high temperature. The polymer maintains longer molecular chains, offering:
- Higher viscosity retention after prolonged heating.
- Reduced breakdown under steam or cyclic thermal shock.
- Sustained elasticity aiding in pore-scale displacement efficiency.
- Greater mobility control across a range of thermal cycles.
