PAC HV is a high-quality grade of poly-anionic cellulose polymer which is widely use to minimize filtration and increase rheological properties in water-based drilling fluid. It is stable up to 300°F and is applicable in different types of water such as fresh to high-saline ones. PAC HV is optimized for drilling fluids needing low filtration properties as well as high rheological characteristics.


  • Easy to mix through hopper
  • Compatible with most types of regular water-based muds
  • Stable up to 250° F
  • Provide excellent filtration control
  • Improve rheological properties
  • Environmentally acceptable
  • Effective in wide range of pH


Main function of PAC HV is to minimize filtration and water loss in water based mud in low to high temperatures. The second function of PAC HV is increasing rheological properties such as yield point for hole cleaning and suspension of weighting agents. PAC HV is an excellent choice for areas which are sensitive for water invasion such as shale layers. Based on required filtration and rheological properties and type of drilling fluid, optimum concentration of PAC HV can be selected.

Safety tips


Eye Contact:

If this product comes in contact with the eyes:
Wash out immediately with fresh running water.
Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids.
If pain persists or recurs seek medical attention.
Removal of contact lenses after an eye injury should only be undertaken by skilled personnel

Skin Contact:

Brush off dust.
If skin or hair contact occurs:

  • Flush skin and hair with running water (and soap if available).
  • Seek medical attention in event of irritation.


If dust is inhaled, remove from contaminated area.

  • Encourage patient to blow nose to ensure clear breathing passages.
  • Ask patient to rinse mouth with water but to not drink water.
  • Seek immediate medical attention.


  • If swallowed do NOT induce vomiting.
  • If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. Observe the patient carefully. Give water to rinse out mouth, then provide liquid slowly and as much as casualty can

comfortably drink. Seek medical advice.
