Filtrate Reducer LV

PAC-L is a modified polyanionic cellulosic polymer (PAC) with minimum impact on mud viscosity. It provides filtration control in bentonite-based drilling fluids and increases water absorption capacity. Optimal results will be obtained by using PAC-L as an additive to the Phrikolat sodium Bentonite Type W.

  • Increases filter cake properties of bentonite muds
  • Reduces fluid loss of bentonite muds
  • Provides filtration control in fresh or salt water muds
  • Increases water absorption capacity
  • Improves flow properties of most drilling fluids
  • Acts as protective colloid for bentonite
  • Reduces swelling and dispersion of drilled clay/cuttings
  • Promotes bore hole stability in water sensitive formations

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

Recommended Concentrations:
Added to bentonite muds: 1-4 kg/m³
Special applications: 4-8 kg/m³

Using a high shear jet-type mixer (venturi) is highly recommended. PAC-L 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-L as fresh water.
