EOR Polymer HPAM for Improved Oil Recovery and Mobility Ratio
Advanced HPAM polymer for mobility ratio adjustment, sweep improvement, and enhanced oil recovery performance.
This EOR-grade HPAM (Partially Hydrolyzed Polyacrylamide) is specifically formulated to optimize mobility ratio and maximize hydrocarbon recovery during polymer flooding. Its high molecular weight, excellent hydration behavior, and stable rheology make it suitable for a wide range of reservoir conditions where improved sweep efficiency is essential.
Purpose and Performance
The primary purpose of this HPAM polymer is to balance the mobility ratio between injected water and crude oil. By enhancing the viscosity of the water phase, the polymer slows down the flow of injected fluid, reducing channeling and forcing the water front to contact bypassed oil. This leads to a more uniform displacement profile and higher incremental recovery.
Core Advantages
Superior viscosity-building capacity at low polymer dosage.
High molecular weight with strong elastic behavior in brine solutions.
Improved mobility ratio leading to greater sweep and displacement efficiency.
Low mechanical degradation during mixing and injection.
Consistent quality suitable for continuous or slug polymer flooding.
Mechanism: Enhancing Mobility Ratio
Mobility ratio is a critical parameter in EOR design. When water moves faster than oil within the reservoir, it creates an unstable displacement front. HPAM corrects this imbalance by creating a more viscous, slower-moving injected phase, which helps push oil ahead more effectively and reduces early water breakthrough.
Field Suitability
Reservoir temperature: Optimal for low-to-medium temperature conditions.
Formation water salinity: Compatible with low and moderate salinity; requires testing for divalent-rich brines.
Rock type: Most effective in sandstone reservoirs.
Target projects: Polymer flooding, conformance improvement, and water management programs.
Conduct formation water compatibility, polymer aging testing, and rheology measurements before full-scale injection.

Final Notes for Engineers
EOR success depends on a well-designed mobility ratio strategy. This HPAM polymer is engineered to deliver consistent viscosity performance, predictable rheology, and long-term injectivity stability. When combined with proper water treatment, pilot validation, and continuous monitoring, the polymer enables significant improvements in oil displacement and field productivity.
