High molecular weight anionic polyacrylamide helps increase the viscosity of injection water. By improving the mobility ratio between injected water and crude oil, polymer flooding can help the injected fluid sweep a larger reservoir area and support improved oil recovery performance.

BLUFLOC anionic PAM is suitable for oilfield customers, EOR service companies, polymer flooding projects and chemical distributors looking for a high molecular weight PAM for mobility control and reservoir sweep efficiency improvement.

After the powder is fully dissolved in water, high molecular weight anionic polyacrylamide forms a viscous polymer solution. This solution is injected into the reservoir through injection wells.

Compared with plain water, the polymer solution has higher viscosity. This helps reduce the speed difference between injected water and crude oil, improving mobility control and helping the injection fluid sweep more of the reservoir.

In suitable conditions, polymer flooding can help push more remaining oil toward production wells and improve oil recovery efficiency.

EOR polymer selection should be based on actual reservoir and injection water conditions. Important factors include reservoir temperature, injection water salinity, calcium and magnesium hardness, reservoir permeability, crude oil viscosity, target polymer solution viscosity, shear conditions during mixing and injection, compatibility with other oilfield chemicals and required polymer concentration.

For EOR polymer flooding, laboratory evaluation is strongly recommended before field application. Tests may include viscosity testing, salinity tolerance, thermal stability, shear stability, filtration performance and core flooding evaluation.

The actual polymer concentration depends on target injection viscosity, reservoir conditions, water salinity, temperature, permeability and project design.

For EOR polymer flooding, the final dosage should be determined by laboratory testing and field pilot evaluation.

Bluwat can provide product selection support and recommend suitable anionic PAM grades according to customer reservoir information, injection water quality and target viscosity requirements.

Because EOR conditions are more sensitive to reservoir temperature, salinity and hardness, product selection should be based on laboratory evaluation and reservoir data.
