Electric Strike Description
When working near electric cables, remember the following:
• Electricity follows all paths to ground, not just path of least resistance.
• Pipes, hoses, and cables will conduct electricity back to all equipment.
• Low voltage current can injure or kill. Almost one-third of work-related electrocutions result from
contact with less than 440 volts.
Most electric strikes are not noticeable, but indications of a strike include:
• power outage
•smoke
•explosion
• popping noises
• arcing electricity
If any of these occur, assume an electric strike has occurred.

Polymer
Polymer
This drilling fluid additive provides excellent lubrication and increases viscosity in average soils and heavy
clay. In swelling clay, polymer can reduce swelling that traps pipe in the bore.
There are two types of polymer:
• long chain such as Baroid EZ-Mud
• medium chain such as Baroid Quik-Trol
Bentonite
Bentonite is a dry powder. When properly mixed with water, it forms a thin cake on bore walls, lubricating
the bore, keeping it open, and holding fluid in the bore.
Some things to remember when mixing bentonite:
• Use clean water free of salt, calcium, or excessive chlorine.
• Use water with pH level between 9 and 10.
• Use water with hardness of less than 120 ppm.
• Do not use bentonite containing sand.
• Mix bentonite thoroughly or it will settle in tank.
• Do not mix bentonite to a funnel viscosity of over 50.
For information on measuring funnel viscosity, see “Funnel Viscosity” on page 42.

Mixtures
NOTICE: Bentonite does not mix well in water containing polymer. To use both, mix bentonite first, then
add polymer.
• If chemicals are added in the wrong order, they will not mix properly and will form clumps.
• If tank contains bentonite/polymer mix and more drilling fluid is needed, completely empty tank and
start with fresh water before mixing another batch.
General mixing order
1. Soda ash
2. Bentonite

Drilling Fluid Requirements
Drilling Fluid Requirements
1. Determine drilling conditions and choose appropriate drilling fluid mix.
2. Estimate amount 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.
• Use meter or pH test strips to test pH of water. If pH is below 9.0, add 1 lb (454 g) soda ash per
tank. Test and repeat until pH is between 9 and 10.
• Check water hardness using hardness test strips. Treat with soda ash if hardness exceeds 125
ppm.
Funnel Viscosity
Viscosity is the measure of internal resistance of a fluid to flow; the greater the resistance, the higher the
viscosity. Viscosity of drilling fluids must be controlled.
To determine viscosity, you will need a Marsh funnel (p/n 259-267) and a measuring cup, available from
your Ditch Witch dealer.
IMPORTANT: Make sure Marsh funnel is clean and free of obstruction and that you have a stopwatch
available for timing the viscosity.
1. Using wash hose and a clean container, take a fresh
sample of drilling fluid. The sample must be at least
1.5 qt (1.4 L).
2. With finger over bottom of funnel, fill with fluid from
the container through the screen until fluid reaches
the bottom of the screen.
3. Move funnel over 1 qt (.95 L) container.
4. Remove finger from bottom of funnel and use the
stopwatch to count the number of seconds it t akes for
1 qt (.95 L) of fluid to pass through the funnel. The
number of seconds is the viscosity.
5. Thoroughly rinse measuring cup and Marsh funnel.
