PAC R

Viscosifier - Filtrate Control Additive

PAC-R is a modified natural polyanionic cellulosic polymer (PAC). It is exhibits high viscosity and is readily dispersible and water soluble. PAC-R provides filtration control in bentonite-based drilling fluids and increases water absorption capacity. Optimal results will be obtained by using PAC-R as an additive to the Phrikolat sodium Bentonite Type W.

Applications:
Horizontal Directional Drilling (HDD), Water Well Drilling, Vertical & Oil Field Drilling, Pipe Jacking

Properties:

• Improves filter cake properties of bentonite muds
• Provides filtration control in fresh or salt water muds
• Increases water absorption capacity
• Improves flow properties of most drilling fluids
• Minimizes torque and circulating pressure
• Acts as protective colloid for bentonite
• Reduces swelling and dispersion of drilled clay/cuttings
• Promotes bore hole stability in water sensitive formations
• Effective in small quantities
• No biocides or preservatives required

PAC-R is compatible with all Phrikolat bentonites & additives and does not contain any harmful ingredients.

Recommended Concentrations:
Added to bentonite muds: 0,5-1 kg/m³
To stabilize Water sensitive formations: 2-4 kg/m³

Using a high shear jet-type mixer (venturi) is highly recommended. PAC-R should always be added to the system after bentonite. Adding should be done slowly and uniformly to the entire circulating system. Salt water may require twice as much PAC-R as fresh water.
