BENTONE® 920
Economical rheological additive for drilling muds and working fluids in low temperature environments
BENTONE 920 rheological additive is an easy to disperse, rapid yielding, economical organobentonite viscosifier for oil–based muds, invert emulsion muds, completion fluids and workover fluids.
BENTONE 920's unique composition delivers a dry process gellant that requires less time and shear to build full rheology in drilling fluids, and that yields at low field temperatures. BENTONE 920 is also significantly more efficient in mineral oils and alpha olefins than conventional organoclay viscosifiers.
BENTONE 920 is suitable for drilling fluids based on mineral and other low toxicity oils, synthetics, as well as diesel and crude oils.
Key properties
- Disperses easily in less time with less shear
