Guidelines

Match drilling fluid to soil type. This chart is meant as a guideline only. See your local Ditch Witch dealer for
soil conditions and drilling fluid recommendations for your area.

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

Soil type

Drilling fluid recommendation

smooth, flowing sand

bentonite or Bore-Gel + medium chain polymer

coarse sand or light soil

bentonite or Bore-Gel

heavy clay

long chain polymer + Con-Det

swelling clay

long chain polymer + Con-Det

rock

Bore-Gel
