Anionic Polyacrylamide APAM 0.1-0.5% Working Solution for Low-Solids Water-Based Drilling Fluid in 750kg Net Big Bag

Product overview

A low-solids drilling-fluid program aims to develop the required fluid properties while controlling the accumulation of unwanted fine solids. A compatible polymer may contribute to viscosity development or interaction with clay and cuttings, depending on the grade and formulation.

Bluwat APAM screening should focus on the intended solids-management strategy. A polymer that flocculates fine particles may assist a removal step in one system and disturb a deliberately maintained dispersion in another. Grade selection therefore needs the base-fluid recipe, solids-control arrangement and acceptance criteria.

Technical specifications

Grade selection for this application

Define the acceptable solids content, clay system, water chemistry and the role expected from the polymer. Confirm whether the process seeks cuttings encapsulation, controlled flocculation or viscosity development, since these objectives require different screening priorities.

Use the general 0.1–0.5% preparation range to develop a workable make-up procedure. It does not mean that every low-solids mud should contain that concentration of APAM. Evaluate the final fluid after dilution, aging and contact with representative drilled solids.

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.
