GLO VIS 2000
Description:
It is a special type high molecular weight polymers
and are used in very small quantity to increase
the viscosity of OCMA. Bentonite suspension of
very low concentration of bentonite in the system.
Application:
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 solid
drilling fluids. It also tends to cause drilled
solids to form agglomerates and settle out. This
further enhance its use as an additive in weighted
and unweighted, non-dispersed drilling fluid systems.
COMMON NAME - BENTONITE EXTENDER
(OCMA)
Advantages:
- It extends the yield of bentonite and is
capable of doubling the yield of bentonite in
very concentration.
- Penetration rates areimproved 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.
