Extra High Yield™ Bentonite (EHYB) is specially peptized high yield bentonite that disperses and hydrates to provide excellent hole cleaning capability and well bore stabilization. This product is NSF 60 certified for use in potable water applications and is nontoxic to the environment.
Extra High Yield™ Bentonite for Non-Oilfield
May be used for all types of freshwater drilling but yield may vary depending on quality of water. High salinity or low pH will adversely affect yield. Ideal pH range for hydration is 8-10 and total hardness should be less than 80 mg/L (Calcium + Magnesium).
- 40 kg/m³ regular drilling applications
- 60-80 kg/m³ Lost circulation applications for suspension of LCM solids
- 15-20 kg/m³ As filter cake enhancer in polymer systems
Pre-hydrate in fresh water before adding to salt or brackish fluid. Expect yield to be diminished.
