Bentonite Extender  is a special type high molecular weight polymer and is used in very small quantity to increase the viscosity of API Bentonite suspension of very low concentration of Bentonite in the system. It is essentially used as a Viscosifier for the Drilling Mud Systems.


Bentonite Extender with its two-fold yield is able to maintain a given viscosity with one-half the normal clay solids. This is an excellent additive for low solid drilling fluids. It also tends to cause drilled solids to form agglomerates and settle out. This further enhances its use as an additive in weighted and unweighted non-dispersed drilling fluid systems.

Common Name- Bentonite Extender or Viscosifier


  • It extends the yield of Bentonite and is capable of doubling the yield of Bentonite
  •  Penetration rates are improved by better solid control.
  •  Bit bearing life is extended by better solids control.
  •  Mixing time is reduced due to lower Bentonite concentration necessary for required Rheology.
  •  Less wall cake builds up due to minimum amount of drilled solids.
  •  Reduces Fluid Loss and overall Drilling costs
