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
