Bentonite extender (api)

Description:

SWE VIS-1000 is special type high molecular weight polymers and are used in very small quantity to increase the viscosity of API Bentonite suspension of very low concentration of bentonite in the system.

Application:-

SWE VIS-1000 bentonite extender with its two-fold yield is able to maintain a given viscosity with one-half the normal clay solids, This is excellent additive for low solids 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.

Advantage:

• SWE VIS-1000 extends the yield of bentonite and capable of doubling the yield of bentonite in very low concentration;

• 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 build up due to minimum amount of drilled solids.
