5-100% Anionic Degree APAM Anionic Polyacrylamide 20-100 Mesh 89% Minimum Solid Content for Drilling Mud

Product overview

Geothermal drilling can expose fluids to demanding temperature histories and variable water chemistry. An anionic polymer may be considered only where the selected grade retains the properties needed for the actual duty. Cool surface handling conditions alone do not establish downhole suitability.

Bluwat can discuss APAM candidates for screening, with the final choice governed by evidence from the intended mud. If the project requires proven high-temperature performance, obtain the necessary grade-specific data or select an alternative chemistry through the fluid-development program. The general Blufloc TDS contains no geothermal temperature rating.

Technical specifications

Grade selection for this application

Provide the expected circulating and static temperatures, exposure duration, base-water chemistry, solids and other additives. Specify the properties that must be retained after aging, such as viscosity profile, filtration response and acceptable fluid appearance.

Evaluate both the make-up stage and the most demanding expected thermal exposure. A grade that dissolves well initially may not retain adequate properties after aging. Do not interpret the powder storage range of 0–35°C as an operating limit or as evidence of stability at geothermal temperatures.

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.
