Anionic Polyacrylamide APAM 5-100% Anionic Degree 20-100 Mesh for Drilling Mud in 750kg Net Big Bag

Product overview

Water-based muds may need additional lubrication to meet the mechanical demands of a drilling interval. A suitable polymer can be considered as part of the fluid package, but lubrication support must be demonstrated by testing rather than inferred from the polymer's anionic charge or viscosity alone.

Bluwat can discuss candidate APAM grades for evaluation with the customer's mud. The objective is to compare any lubricity benefit with changes in rheology, solids interaction and additive compatibility. A polymer that builds viscosity is not automatically an effective torque-and-drag treatment, and a dedicated lubricant may still be required.

Product benefits

Technical specifications

Grade selection for this application

Provide the base fluid, solids loading, salinity, existing lubricant and the intended lubricity assessment method. Compare the complete formulation because polymer adsorption and solids behavior can change both fluid handling and the result of a friction test.

Use the 5–100% anionic-degree range as a family description, not as a recommended charge setting. Choose one grade for each test and record its identity. If the goal is lower drillstring friction, examine the mechanical-contact measurement directly rather than substituting a pipe pressure-drop result.

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.
