DYNARED™ Seepage Control Fiber

DYNARED™ Fiber is a proprietary micro-cellulosic fiber for use in seepage loss control and other lost circulation needs. The product is available in fine, medium and coarse grades. DYNARED™ Fiber unlike other seepage control materials has minimal effects on rheological properties. DYNARED™ fiber exhibits excellent return permeabilities.


  • May be mixed rapidly through the mud hopper
  • Does not require bypassing of most solids control equipment
  • Seals off depleted zones without excessive build up of wall cake
  • Does not need addition of a wetting agent to go into oil based fluids
  • Is not treated with a wetting agent so it may be used in water based fluids
  • Unlike competitive materials does not appreciably increase drilling fluid rheology
  • Does not readily degrade due to shear
  • Resistant to attack by bio-organisms
  • Works in drilling fluids of any pH
  • Compatible with other common lost circulation materials
  • May be used in water base mud
