Highly active bentonites for controlled rheological performance
The high proportion of the mineral species montmorillonite provides a unique structure with very high activity. TRUGEL™ enables key drilling functionalities:
- Provides thixotropic behavior to both hold and transport cuttings in suspension, depending on shear conditions
- Flat, plate-like particle deposition creates an impermeable cake on the walls of the drill hole
- Stabilizes and maintains the drill hole
- Maintains rheological performance and limits filtrate loss at high temperatures (400+)
TRUGEL™ API 13A grade premium bentonite not only forms a protective filter cake to control fluid loss, it also reduces NPT caused by differential stuck pipe.
