Advantages:

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

Applications:

• Drilling mud (gel) is crucial in the extraction of drill cutting during the drilling processes.
• Drilling mud (gel) is a major component in well drilling process.
• 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.
