Seit mehr als 25 Jahren ist das Hauptgeschäftsfeld der Phrikolat Drilling Specialties GmbH die Bereitstellung von Bohrspülungen für die gesteuerte Horizontalbohrtechnik. Auf diesem Gebiet hat sich Phrikolat hochspezialisiert und eine Reihe exklusiv angebotener Bohrspülungen und Bohrspülungsadditive entwickelt, inbesondere für komplizierte Baugrundverhältnisse. Phrikolat bietet nicht nur Bohrspülungssysteme für den Bereich Horizontal Directional Drilling (HDD), sondern auch für Microtunneling, Rohrvortrieb, Brunnenbau und Tiefbohrtechnik.PAC L
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.
Applications:
Horizontal Directional Drilling (HDD), Water Well Drilling, Vertical & Oil Field Drilling, Pipe Jacking
Properties:
- 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.
Packaging:
