BENTOPRODRILL-A is an exceptional OCMA grade, sodium activated bentonite with yield higher than 18m3/t for suspension of 15cP of apparent viscosity. It provides drilling fluid of high viscosity and low fluid loss. It is suitable for preparation of water-based drilling fluids for all types of drilling operations, and it is specifically recommended for initial drilling depths of up to 500m. It is suitable to be mixed with polymers and other additives.

BENTOPRODRILL-A performs the following main functions:

• Excellent for lubricating and cooling the drilling bit
• Reduces the fluid loss through the borehole walls
• Efficient in removing cuttings to the surface
• Keeps cuttings in the suspension when the drilling is stopped
• Stabilizes the borehole and creates the impermeable lining on borehole walls
• Well combined with polymers and other additives
