Product category
Drilling Bentonite
In drilling, bentonite carries cuttings to the surface, forms a film on the borehole wall to reduce friction, and helps protect drill bits from abrasion.
Main applications
- Water well drilling
- Deep well drilling
- Oil and gas drilling
- Horizontal directional drilling
Product forms
- Milled powder
Packaging options
- 25 kg bags
- Big bags (jumbo bags)
- Bulk supply on request
Technical data & laboratory analysis
Technical specifications
Arminakil drilling bentonite is developed to build viscosity in water-based drilling fluids, support borehole stability and help carry cuttings. Performance depends on mineral structure, milling fineness, water quality and drilling conditions.
