Anionic Polyacrylamide APAM pH 6-8 in 1% Solution for Cuttings Suspension and Hole Cleaning Drilling Mud Additive

Product overview

Effective hole cleaning depends on more than bulk fluid viscosity. Flow rate, annular geometry, hole inclination, cuttings size and the mud's low-shear behavior all influence transport. Blufloc APAM can be screened as a polymer component where additional viscosity development is compatible with the overall fluid design.

The target is a useful transport response with manageable pressure losses and restart behavior. Polymer selection should examine both circulating performance and the suspension behavior during interruptions. A thicker laboratory sample does not by itself demonstrate improved cleaning in an actual well.

Product benefits

Technical specifications

Grade selection for this application

Provide hole size and inclination, planned circulation rates, mud density, cuttings characteristics and the complete additive package. Include the expected water quality and temperature because clean-water polymer response may differ from behavior in a loaded drilling mud.

Compare suspension and carrying behavior against pumpability, equivalent circulating density constraints and gel development. Excessive gels can make restart conditions less manageable. Select a grade and treatment level that work with the circulation program rather than using polymer addition as the only adjustment.

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 PE 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.
