Filter High

High-viscosity PAC polymer reduces fluid loss to the formation while providing increased viscosity to improve hole cleaning and suspension.

Filter High is effective at low concentrations. It can be used in freshwater, seawater, and brines up to 149°C.

APPLICATIONS

Filter High reduces fluid loss and increases viscosity in water-based drilling fluids. It efficiently achieves results in oil and gas, geothermal, waterwell, HDD, diamond coring, tunnelling, piling, and construction applications.

Filter High is commonly added to a bentonite slurry to build a stronger, thinner filter cake and reduce formation loss. It provides increased suspension while delivering high viscosity.

Filter High can be used in a bentonite-free system. It provides viscosity, reduces fluid loss, stabilises reactive shales, and enhances lubrication. It forms a thin filter cake and reduces cutting settling.

If a low-viscosity system is preferred, Filter Low is a better choice.

SPECIFICATIONS
Physical Appearance: White or Tan powder

RECOMMENDED TREATMENT
In a bentonite-based system, typical concentrations range from 0.5 - 1.5kg/m3.

In a bentonite-free system, typical concentrations range from 1.0 - 2.0kg/m3.

In an oil and gas or geothermal programme, concentrations may be higher.

Add slowly through the hopper.
