Anionic Polyacrylamide APAM Powder with 0.05% Max Residual Monomer for EOR Polymer Flooding in 750kg Net Big Bag

Product overview

Polymer flooding seeks a suitable displacement-fluid mobility by increasing the viscosity of the injected aqueous phase. A candidate APAM must do more than produce a thick solution: it must also be prepared reliably and pass through the intended injection system and reservoir without unacceptable pressure or retention behavior.

Bluwat's general APAM family provides a starting point for technical discussion. The TDS does not identify a reservoir-qualified EOR grade, state a viscosity guarantee in a specified brine or provide core-flood results. Confirm the selected chemistry and project-specific qualification data before planning field injection.

Product benefits

Technical specifications

Grade selection for this application

Supply reservoir temperature, injection-water composition, calcium and magnesium levels, crude-oil viscosity, rock properties and the desired mobility target. Include injection-equipment details and the planned polymer residence time so the test program represents the whole process.

Assess dissolution quality, solution filtration, mechanical degradation, long-term aging, retention and injectivity. A low residual-monomer value does not establish low insoluble content or reservoir compatibility. Where the project demands salt-resistant or heat-resistant chemistry, request specific supporting data rather than assuming the general APAM range is sufficient.

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 750 kg net big bag. Confirm unloading, metering and moisture-protection requirements for the receiving site. 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.
