Product Description

Product Description

BLACKLEO^® is a highly-oxidized leonardite used to reduce fluid loss and deflocculate water-based mud. It is a partially soluble additive which provide thin, low permeability filter cake. BLACKLEO^® is an excellent emulsifier for oil in water emulsions as well as a secondary deflocculant and is especially effective in high-temperature applications. It performs exceptionally well in dispersed systems as a synergistic additive with EZTHIN^® modified tannin. BLACKLEO^® requires an alkaline environment to solubilize and function therefore should be used at pH 9.0 or above.

Applications/Functions

• Provide improved filtration control and reduce rheology and gel strength in all water-based mud
• Especially effective in stabilizing the properties of muds exposed to high temperatures and contaminants such as CO₂ or Calcium
• Especially effective when treating cement contamination. Reduce the high viscosity and pH of cement-contaminated muds and react with calcium to lessen the contaminating effects

Advantages

• Temperatures stable up to 400°F
• Improves filter cake quality by reducing its thickness and permeability
• Significantly extends the temperature stability of water-based fluids

Typical Properties

• Appearance: Black powder
• Specific gravity: 1.7

Recommended Treatment

• A typical range is 2-12 ppb
• Pre-solubilize BLACKLEO^® with caustic soda (5:1) for best performance

Package

• 25 KG SACK
