Anionic Polyacrylamide APAM pH 6-8 in 1% Solution for EOR Mobility Control in 25kg Kraft Paper Bag

Product overview

An unfavorable water-to-oil mobility relationship can allow the injected water to move through a reservoir inefficiently. Polymer mobility control aims to modify the aqueous-phase viscosity to suit the displacement design. The required viscosity depends on oil properties, relative permeability, reservoir structure and injection limitations.

Bluwat APAM candidates should be compared at explicitly stated concentration, brine composition, temperature and shear conditions. A viscosity value without those conditions is not a reliable basis for grade selection. The general family specification does not establish that a particular candidate will deliver the desired reservoir mobility ratio.

Technical specifications

Grade selection for this application

Share oil viscosity at reservoir conditions, injection-water analysis, reservoir temperature and the proposed displacement assumptions. Include permeability information and operating pressure limits so the polymer choice can be assessed against injectivity as well as thickening efficiency.

Measure a rheological profile instead of relying on a single ambient-water viscosity number. Test the impact of dilution, salinity, aging and mechanical handling. Use the result in the project's reservoir assessment; a thicker solution is useful only if its behavior remains compatible with the planned injection process.

Application evaluation and use

Solution preparation and dosing

Use clean, compatible make-up water and add the powder gradually into an established mixing flow. Avoid dumping powder in one location, which can create lumps with dry cores. The TDS gives 0.1–0.5% as general solution-preparation guidance. If specified on an as-supplied powder mass basis, this corresponds to 1–5 kg of powder per 1,000 kg of final solution; agree the concentration basis for the project.

Allow approximately one hour of agitation as a starting reference, then confirm complete hydration. Water quality, temperature, grade and equipment affect the required time. The TDS’s 200–400 rpm reference is equipment dependent and should not be scaled to a different tank solely by rpm. Avoid severe shear after hydration. Determine the final treatment dosage through the application tests described above.

Packaging storage and handling

The featured packaging is a 25 kg kraft paper bag with an inner plastic liner. The TDS also lists 25 kg kraft paper or PE bags and 750 kg net big bags. Store powder dry, protected from direct sunlight and at 0–35°C. Keep opened packaging tightly closed. Consult the current SDS for handling, spill control and personal protection.
