Bentonite CP-OC is used in vertical drilling fluids to increase viscosity and filtration control. CP-OC is also ideal in drilling fluids because it expands when exposed to water. This expansion helps down hole formations to be sealed from invading drilling fluids. The Drilling bentonite extracts the drill cuttings from around the drill bit, which are then floated to the surface. Bentonite also serves to cool and lubricate the drill bit as well as seals the drill hole against seepage and to prevent wall cave-ins. It is mainly use in fresh pure water rotary drilling conditions as water quality will affect bentonite performance.
Viscometer dial reading at 600r/min

CP-OC is suitable for all type of freshwater mud rotary drilling.
CP-OC can also be used as a seal for earthen structures, slurry trenching, tunnel boring and foundation drill.
