BENTONITE POWDER – API

Bentonite viscosifier is a premium-grade Bentonite (a sodium montmorillonite clay) that will yield 91 to 100 barrels of 15 cp mud per ton (1.7 m3/100Kg). It is used as a primary filter cake –building, filtration-control and suspension agent in freshwater systems, and has application in all water-base mud systems. Bentonite viscosities is a high-quality product which meets the ISO 13500 Clause 9 (formerly known as API Spec 13A, Section 4) specifications for Bentonite.

Typical Physical Properties

Applications

Bentonite viscosifier is used to increase viscosity and reduce fluid-loss in water-base drilling fluids. It is a cost-effective means o achieving viscosity, fluid-loss control and filter cake quality in freshwater and seawater muds. Typical concentrations for Bentoniteviscosifier range from 5 to 35 lb/bbl (14.3 to 100 kg/m3). 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 Bentoniteviscosifier is significantly reduced unless pre-hydrated in freshwater before adding to the mud system.

Advantages

1.     hydrates more than other types of clays and is best for generating viscosity,developing gels for suspension and controlling filtration

2.      small particle size,unique flat shape and high surface area of hydrated Bentoniteviscosifier provides superior filtration characteristics

3.      Promotes the deposition of thin,compressible filter cakes in the wellbore

Limitations

Performance reduced in salty(>5,000 mg/L CI) 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).

Packaging and Storage

Bentoniteviscosifier is packaged in 100-lb (45.4 kg) multi-wall paper sacks, 40 kg sacks, big bags and is available in bulk. Store in dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and/or stacking.
