Non-treated Bentonite API 13A Section 10, the same quality of Wyoming Bentonite meeting the same API standard, but with competitive price on promotion. If you have any interests on this product, please feel free to let us know. We are honored to offer our best price accordingly.
Non- Treated Bentonite Powder is a premium-grade, sodium montmorillonite clay that will yield 91 to 100 barrels of 15-cP mud per ton (1.7 m3/100 kg).
It is used as a primary filter-cakecake-building, filtration-control and suspension agent in
freshwater systems, and has application in all water-base mud systems.
Typical Physical Properties
Physical appearance Light tan/gray-green powder
Specific gravity 2.3 - 2.6
Bulk density 48 - 52lb/ft3 (769 - 833 kg/m3)
It is used to increase viscosity and reduce fluid-loss in water-base drilling fluids. It is a
cost-effective means of achieving viscosity, fluid-loss control and filter-cake quality in
freshwater and seawater muds.
Typical concentrations for Non treated bentonite range from 5 to 35 lb/bbl (14.3 to 100
As with all bentonite products, the yield decreases as water salinity increases. In muds
containing more than 10,000 mg/L chlorides, the performance of it is significantly
reduced unless pre hydrated in freshwater before adding to the mud system.
· Hydrates more than other types of clays and is best for generating viscosity,
developing gels for suspension and controlling filtration
· Small particle size, unique flat shape and high surface area of hydrated and its
viscosifier provides superior filtration characteristics
· Promotes the deposition of thin, compressible filter cakes in the wellbore
Performance reduced in salty (>5,000 mg/L Clˉ) or hard (>240 mg/L Ca++) waters due
to decreased hydration
Toxicity and Handling
Bioassay information is available upon request.
Handle as an industrial chemical, wearing protective equipment and observing the
precautions as described in the Material Safety Data Sheet (MSDS).
