VIS PAC L is used where fluid loss control is required, without affecting the beneficial rheological properties of the drilling fluid and is also effective in flooded reverse drilling where low viscosity fluids are required.

• Disperses quickly and produces minimal viscosity increase while providing fluid loss control
• Encapsulates shale particles to inhibit swelling and dispersion
• Resists bacterial attack, requiring no biocides or preservatives
• Functions over a wide range of salinity, hardness and pH levels
• Applicable in all water-based fluids, ranging from low solids, non-dispersed polymer systems to high-density dispersed systems.

To reduce torque and improve core recovery 1 – 3kg per 1000lt
To stabilize unconsolidated formations, clays etc 3 – 5kg per 1000lt
To improve the properties of a GEL X mud 0.5 – 2.0 kg per 1000lt

Mix slowly through a mud hopper or a PVC eductor.
