  • Reduces the filtration rate of the fluid with minimal effect to the fluid rheology.
  • Effective in both weighted and low solids mud over a wide PH range.
  • Coats and encapsulates cuttings and solids in the drilling fluid, thereby inhibiting the swelling and disintegration of water sensitive solids.
  • Improves the character and consistency of wall cake, thereby reducing the potential for stuck pipe.
  • Maintains performance at down-hole temperatures up to 250 deg F.

Recommended Treatment:

Concentrations in the range of 1.0-4.0 bbl are recommended to control drilling mud properties. The quantity used would be dependent on the drilling fluid system, drilling depth and equipment.
