Filter Low

Low-viscosity PAC polymer that reduces fluid loss to the formation and minimises pressure in the borehole.

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

APPLICATIONS

Filter Low reduces fluid loss with only a small increase in 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 Low is commonly added to a bentonite slurry to build a stronger, thinner filter cake and reduce formation loss.

Filter Low can be used in a bentonite-free system. It reduces fluid loss, stabilises reactive shales, and enhances lubrication by forming a thin filter cake without substantially increasing viscosity.

If a high-viscosity system is preferred, Filter High is a better choice.

SPECIFICATIONS
Physical Appearance: White or Tan powder

RECOMMENDED TREATMENT
In a bentonite-based system, typical concentrations range from 0.5 - 2.5kg/m3.

In a bentonite-free system, typical concentrations range from 1.0 - 4.0kg/m3.

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

Add slowly through the hopper.
