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. Also see our interactive Drilling Fluid
Formulator at www.ditchwitch.com.
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
