Product Description

BENTONITE viscosifier is a finely ground, premium-grade bentonite meets API standards that yield 100 bbls of 15- cp mud per ton (16 m³/ton). It is used in water-based drilling fluids as filter cake building, filtration control and suspension. As with all bentonite products, the yield decreases as water salinity increases. In muds containing more than 10,000 ppm chlorides, the performance of BENTONITE is significantly reduced unless pre-hydrated in freshwater before adding to the mud system.

Applications/Functions

• Increases viscosity and improves hole cleaning
• Reduces filtration rates into permeable zones
• Deposits a thin, tough filter cake
• Stabilizes the wellbore in poorly consolidated formations

Advantages

• Meets API standards and cost-effective
• 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 BENTONITE viscosifier provides superior filtration characteristic

Typical Properties

• Appearance: Tan to gray, free-flowing powder
• Specific gravity: 2.3-2.6

Recommended Treatment

• A typical range is 5-35 ppb. BENTONITE can be mixed directly into the system through the hopper or pre-hydrated in freshwater before being added into the system
• Performance reduced in salinity >5000ppm Cl-or total hardness>200 ppm due to decreased hydration

Package

• 25 KG SACK or 1 MT BAG
