soil conditions and drilling fluid recommendations for your area. Also see our interactive Drilling Fluid

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
