Anionic Polyacrylamide 5 to 25 Million Molecular Weight for Oilfield Drilling Mud Viscosifier and Lubrication
Product Overview
BLUFLOC Anionic Polyacrylamide is a high molecular weight PAM powder designed for water based oilfield drilling mud systems. With a molecular weight range from 5 to 25 million, it can help increase drilling fluid viscosity, improve rheological performance, support cuttings suspension and enhance lubrication during drilling circulation.
In oil drilling operation, drilling mud must maintain proper viscosity and lubrication to carry cuttings, reduce friction, cool drilling tools and protect the borehole wall. When the mud viscosity is too low, cuttings may settle and drilling efficiency may decline. When lubrication is not sufficient, friction between the drill string, mud and formation may increase. BLUFLOC Anionic PAM helps improve the drilling fluid system by forming a high viscosity polymer solution after proper dissolution.
This product is suitable for oilfield drilling mud viscosifier, water based drilling fluid additive, lubrication support, shale stabilization, borehole stability, fluid loss control support and selected oilfield wastewater treatment applications.

Main Applications in Oilfield Drilling
Drilling Mud Viscosifier
BLUFLOC Anionic Polyacrylamide is used to increase the viscosity of water based drilling mud. Proper viscosity helps improve mud carrying capacity, cuttings suspension and drilling fluid circulation stability.
Lubrication Support
A properly dissolved PAM solution can help improve the lubricating property of drilling mud. Better lubrication supports smoother drilling operation and helps reduce friction in the drilling process.
Water Based Drilling Fluid Additive
This product is suitable for water based drilling mud systems where high molecular weight anionic polymer is required. It can be used as a functional additive to improve mud rheology, viscosity and overall fluid stability.
Cuttings Suspension
During drilling, cuttings must be transported from the bottom of the well to the surface. Anionic PAM helps improve suspension performance and supports the carrying capacity of drilling fluid.
Borehole Stability
Stable drilling mud is important for borehole wall protection. BLUFLOC Anionic PAM helps improve the mud structure and supports borehole stability in drilling operations.
Shale Stabilization
In shale or clay rich formations, water invasion can cause swelling and dispersion. Anionic PAM can support shale stabilization by improving the performance of water based drilling mud and helping reduce instability caused by poor mud control.
Fluid Loss Control Support
Although this product page focuses on viscosifying and lubrication, high molecular weight anionic PAM can also support fluid loss control by improving drilling mud structure and filtration behavior.
Oilfield Wastewater Treatment
Anionic PAM can also be used in selected oilfield wastewater clarification, mud water separation and suspended solids settling applications where solid liquid separation is required.
Why 5 to 25 Million Molecular Weight Matters
The molecular weight of polyacrylamide strongly affects viscosity building performance. A higher molecular weight PAM can form a stronger polymer chain network in water, helping improve drilling mud viscosity and suspension performance at low dosage levels.
For oilfield drilling mud, the 5 to 25 million molecular weight range allows customers to select different viscosity levels according to drilling conditions, mud formulation, water quality, salinity and target performance.
Bluwat can recommend suitable anionic PAM grades according to customer requirements, including HA7525 and other high molecular weight grades.
How It Works in Drilling Mud
After proper dissolution, BLUFLOC Anionic PAM forms a viscous polymer solution. When added into the drilling mud system, it helps improve viscosity, rheology, lubrication and suspension capacity.
This supports better drilling fluid circulation, helps carry cuttings more efficiently and improves the stability of the water based mud system. It can also work together with other drilling fluid additives depending on the formulation design.
Typical Problems This Product Can Help Improve
Drilling mud viscosity is too low
Poor cuttings suspension
High friction during drilling circulation
Unstable water based drilling mud performance
Weak borehole wall protection
Shale swelling and dispersion tendency
Poor mud rheology control
Need for economical drilling mud viscosifier
Need for high molecular weight oilfield polymer additive
Recommended Solution Preparation
Prepare the polymer solution at 0.1 to 0.5 percent concentration.
Add the powder slowly and evenly into clean water.
Keep continuous agitation during powder addition.
Recommended agitation speed is 200 to 400 rpm.
Normal dissolving time is about 1 hour.
Avoid adding powder too quickly because lumping may occur.
Avoid excessive high speed agitation because it may damage polymer molecular chains.
Make sure the polymer is fully dissolved before dosing into the drilling fluid system.
General Dosing Guidance
The actual dosage depends on drilling mud formulation, water salinity, temperature, mud density, shale activity, target viscosity and lubrication requirement.
Laboratory testing or pilot testing is recommended before field application.
For drilling mud viscosifier and lubrication support, the product should be selected according to required viscosity, mud compatibility and field operating conditions.
Bluwat can provide product selection support and dosing recommendations based on customer drilling fluid requirements.
