HA6518 High Molecular Weight Anionic Polyacrylamide Powder for Cuttings Suspension in 20 to 100 Mesh Drilling Mud Additive
HA6518 Anionic Polyacrylamide Powder for Oilfield Drilling Mud Additive and Cuttings Suspension
BLUFLOC HA6518 Anionic Polyacrylamide Powder is a high molecular weight water soluble polymer designed for water based oilfield drilling mud applications. It helps improve cuttings suspension, mud carrying capacity, viscosity support, rheology control, lubrication performance and drilling fluid stability.
In oil drilling operations, drilling mud must carry cuttings from the bottom of the well to the surface. When viscosity and suspension capacity are not stable, cuttings may settle in the borehole, mud circulation may become less efficient and drilling risk may increase. HA6518 supports a more stable drilling fluid system for better solids transport and cleaner borehole conditions.

Main Applications in Oilfield Drilling
Drilling Mud Additive
HA6518 helps improve viscosity, suspension, rheology and overall mud performance in water based drilling mud systems.
Cuttings Suspension
The product helps increase fluid carrying capacity, allowing drill cuttings and fine solids to remain suspended during circulation.
Mud Carrying Capacity Improvement
When drilling mud has poor carrying capacity, cuttings may settle in the borehole. HA6518 supports better solids transport.
Water Based Mud Viscosity Support
Proper viscosity supports drilling fluid circulation, cuttings transport and mud stability.
Rheology Control
Stable rheology is important for drilling efficiency. HA6518 supports more stable field performance under normal operating conditions.
Lubrication Support
After proper dissolution, HA6518 forms a polymer solution that can support lubrication in water based mud.
Shale Stabilization
In shale and clay rich formations, HA6518 can support mud system performance and help reduce instability caused by poor mud control.
Oilfield Wastewater Treatment
HA6518 can also be used in selected oilfield wastewater clarification and drilling mud water treatment systems.
Why Cuttings Suspension Matters in Drilling Mud
During drilling, rock cuttings are continuously generated at the drill bit. These cuttings must be carried upward by the drilling fluid. If cuttings are not suspended and transported properly, several problems may occur.
- Cuttings may settle in the wellbore.
- Mud circulation may become unstable.
- Drilling efficiency may decrease.
- The risk of stuck pipe may increase.
- Borehole cleaning may become more difficult.
- Downstream solids control equipment may become overloaded.
HA6518 Solution
HA6518 helps improve the suspension and carrying capacity of the drilling mud, supporting cleaner borehole conditions and more stable drilling operation.
The polymer structure helps fine solids and cuttings remain better suspended in the mud system. It also supports more stable rheology, better mud consistency and smoother circulation.
How HA6518 Works in Water Based Drilling Mud
After HA6518 powder is fully dissolved in water, it forms a high molecular weight polymer solution. When added into water based drilling mud, the polymer chains help improve viscosity and suspension performance.
This polymer structure helps fine solids and cuttings remain better suspended in the mud system. It also supports more stable rheology, better mud consistency and smoother circulation.
In suitable formulations, HA6518 may also help improve lubrication, reduce fine solids dispersion and support borehole wall stability.
Typical Problems HA6518 Can Help Improve
Poor Suspension
Poor cuttings suspension and cuttings settling during mud circulation.
Weak Mud Carrying Capacity
Low carrying capacity may cause solids accumulation and unstable circulation.
Unstable Viscosity
Low or unstable drilling fluid viscosity can reduce drilling mud performance.
Poor Rheology
Poor water based mud rheology may affect circulation and solids transport.
High Friction
HA6518 can support lubrication after proper dissolution in water based mud.
Shale Instability
Supports shale stabilization and borehole stability in sensitive formations.
Recommended Solution Preparation
Prepare Polymer Solution
Prepare HA6518 solution at 0.1 to 0.5 percent concentration.
Add Powder Slowly
Add the powder slowly and evenly into clean water while keeping continuous agitation.
Control Mixing Speed
Recommended agitation speed is 200 to 400 rpm. Avoid excessive high speed agitation because it may damage polymer molecular chains.
Allow Full Dissolution
Normal dissolving time is about 1 hour. Make sure the polymer is fully dissolved before dosing.
Avoid Lumping
Avoid adding powder too quickly because lumping may occur. Incomplete dissolution may reduce viscosity, suspension and drilling mud performance.
General Dosing Guidance
The actual dosage depends on drilling mud formulation, water quality, salinity, temperature, mud density, cuttings load, shale activity, target viscosity and field operating conditions.
Laboratory testing or field trial is recommended before large scale use. For cuttings suspension, HA6518 should be tested with the existing drilling mud system to confirm viscosity response, compatibility with other additives and final performance.
Bluwat can provide product selection support and dosing recommendations according to customer drilling fluid requirements.
Suggested Application Process
Prepare Solution
Prepare a 0.1 to 0.5 percent HA6518 polymer solution.
Dissolve Completely
