Extra High Yield™ Bentonite for Non-Oilfield

• High viscosity for bit face evacuation and cuttings transport
• Creates filter cake for wellbore stability
• Exhibits gel strength for static cutting suspension
• Increased lubrication to bit and tubulars over water alone
• Inexpensive viscosifier for lost circulation situations
• Easily clarified by flocculation and coagulation with appropriate additives

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.
