Applications:
1. Drilling mud (gel) is crucial in the extraction of drill cutting during the
drilling
processes.
2. Drilling mud (gel) is a major component in well drilling process.
3. Another conventional use of bentonite is as a mud constituent for oil
and
water well drilling. Its roles are mainly to seal the borehole walls, to remove
drill
cuttings and to lubricate the cutting head.
Note: All the test carried out as per IS Standard.

Advantage:
1. Bentonite extracts the drill cutting from around the bit which is then
floated
to the surface.
2. Bentonite seals the drill hole against seepage and prevents wall cavities
and
leakages.
3. Bentonite (Drilling mud) served to cool and lubricate the drill bit.
4. Bentonite form slurry with leakages that is pumped through drill stem
and out
through drill bit.
