Bentonite CP-OC Is Used in Vertical Drilling Fluids To Increase Viscosity And Filtration Control.

Product Description

Bentonite CP-OC

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.


Advantages

Good suspension

High thixotropy

Little filtrated volume

Excellent capacity of making mud

Easy to adjust the density of the well drilling slurry

Application

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.


Mixing and dosage

Mixing ratios are based on the use of freshwater; water purity will affect bentonite performance. For best results, acidic and hard make-up water should be pretreated with SODA ASH to a pH of 8.5-9.5. Add PREMIUM GEL slowly through jet/hopper mixer.The quantity of bentonite used is variable depending upon the depth of the hole to be drilled. Generally one tonne of bentonite is used to prepare about 100 barrels of mud.
