Salt-Resistant Temperature-Resistant High Molecular Weight PHPA HPAM Polyacrylamide for EOR Mobility Control

Polymer for EOR Mobility Control in Harsh Reservoir Conditions

Product Overview

Salt-Resistant and Temperature-Resistant PHPA Polyacrylamide is an advanced oilfield-grade polymer developed for Enhanced Oil Recovery (EOR) mobility control under challenging reservoir conditions.

The BLUFLOC® Oilfield PHPA Series from Bluwat Chemicals is engineered to maintain viscosity stability and displacement efficiency in high salinity formation water, elevated temperatures, and complex geological environments.

This polymer is specifically designed for tertiary oil recovery projects where conventional polymers may suffer from viscosity loss or thermal degradation.

Designed for Harsh Reservoir Conditions

Oil reservoirs with high mineral content and elevated temperature can significantly reduce the effectiveness of standard polymers.

Salt- and temperature-resistant PHPA is formulated to:

• Maintain viscosity in saline injection water

• Resist thermal degradation at higher reservoir temperatures

• Provide stable mobility control during long injection cycles

• Improve sweep efficiency in heterogeneous formations

• Reduce early water breakthrough

This ensures consistent polymer flooding performance throughout the project lifecycle.

Role in EOR Mobility Control

In polymer flooding operations, mobility control is essential to optimize oil displacement.

This PHPA polymer works by:

• Increasing the viscosity of injected water

• Improving the mobility ratio between water and crude oil

• Expanding the swept reservoir area

• Stabilizing the displacement front

• Enhancing ultimate oil recovery

The result is improved reservoir conformance and higher production efficiency.
