PLAN DRILLING FLUID REQUIREMENTS
Mixtures
Bentonite does not mix well in water containing polymer. To use
both, mix bentonite first, then add polymer.
Bore-Gel contains premixed bentonite, polymer, and soda ash.
Use 15 lb/100 gal (6.8 kg/378.5 L) in normal boring conditions
and up to 45 lb/100 gal (20.4 kg/378.5 L) in sand or gravel.
PLAN DRILLING FLUID REQUIREMENTS
1. Determine boring conditions and choose appropriate drilling
fluid mix.
2. Estimate amounts of supplies needed and check availability:
• drilling fluid
• water supply. If more water than can be carried with the
unit will be needed, arrange to transport additional water.
• bentonite and/or polymer
3. Check water quality.
• Using litmus paper, perform a pH test on water.
• If pH is below 5.0, add 1 cup (.25 L) soda ash per tank.
• Test and repeat until pH is between 7.5 and 10.
