HA6518 Anionic Polyacrylamide Powder for Oilfield Drilling Mud Additive and Cuttings Suspension
Product Overview
BLUFLOC HA6518 Anionic Polyacrylamide Powder is a high molecular weight water soluble polymer designed for oilfield drilling mud applications. It is mainly used as a drilling mud additive to improve cuttings suspension, enhance mud carrying capacity, support viscosity control and improve water based drilling fluid performance.
During oil drilling, drilling mud must carry cuttings from the bottom of the well to the surface. If the mud 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 helps improve the structure and rheology of water based drilling mud, allowing the fluid system to suspend and transport solids more effectively.
This product is suitable for drilling fluid systems that require cuttings suspension, viscosity support, mud stabilization, lubrication improvement, shale stabilization and selected fluid loss control support.

Main Applications in Oilfield Drilling
Drilling Mud Additive
HA6518 is used as a functional polymer additive in water based drilling mud. It helps improve viscosity, suspension, rheology and overall mud performance during drilling operations.
Cuttings Suspension
Cuttings suspension is one of the key functions of drilling mud. HA6518 helps increase the carrying capacity of the fluid system, allowing drill cuttings and fine solids to remain suspended during circulation and transport more efficiently to the surface.
Mud Carrying Capacity Improvement
When drilling mud has poor carrying capacity, cuttings may settle in the borehole or accumulate in low flow areas. HA6518 helps improve the mud structure and supports better solids transport.
Water Based Drilling Fluid Viscosity Support
HA6518 can help build viscosity in water based mud systems. Proper viscosity supports drilling fluid circulation, cuttings transport and mud stability.
Rheology Control
Stable rheology is important for drilling efficiency. HA6518 helps improve drilling mud consistency and 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 drilling mud. Better lubrication helps reduce friction during drilling fluid circulation.
Shale Stabilization
In shale and clay rich formations, water invasion may cause swelling and dispersion. HA6518 can support shale stabilization by improving the drilling mud system and helping reduce formation instability caused by poor mud performance.
Fluid Loss Control Support
Although HA6518 is mainly positioned here for drilling mud additive and cuttings suspension, it can also support fluid loss control when used in a suitable drilling fluid formulation.
Oilfield Wastewater and Mud Water Treatment
HA6518 can also be used in selected oilfield wastewater clarification and drilling mud water treatment systems where suspended solids settling and solid liquid separation are required.
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:
HA6518 helps improve the suspension and carrying capacity of the drilling mud, supporting cleaner borehole conditions and more stable drilling operation.
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
Recommended Solution Preparation
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.
