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.

Hydration & Preparation

Hydrating thermal-resistant HPAM requires controlled shear and appropriate preparation methods to preserve molecular weight and achieve target viscosity.
