2-Year Shelf Life Anionic Polyacrylamide APAM with 89% Min Solid Content for KCl Water-Based Drilling Fluid

Product overview

KCl and anionic polymer may serve different roles in a water-based shale-control program. The salt changes the ionic environment, while a suitable polymer can be evaluated for cuttings interaction and fluid-property development. Their combined performance depends on the exact formulation and formation response.

The Blufloc APAM family should not be treated as universally compatible with every KCl concentration or mixed-brine composition. Confirm the selected grade, hydration method and final-fluid behavior. Where a PHPA specification is required, obtain grade-specific confirmation rather than relying only on the generic APAM description.

Product benefits

Technical specifications

Grade selection for this application

Provide KCl concentration, other dissolved salts, calcium and magnesium levels, pH and expected temperature. Include the inhibitor and filtration-control package. The effect of the complete brine on dissolution and viscosity should be measured directly.

Compare direct preparation in the intended water with alternative approved make-up sequences where practical. Do not impose one universal salt-addition order without testing. Once hydrated and blended, the fluid should meet both shale-response and rheology targets after representative aging.

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.
