DESCRIPTION

This black powder is used as anti-high temperature, salt-resistant fluid loss

additive, providing filtration control in water-based drilling fluids. It is

compatible with lignosulfonates and lignites and is capable of handling

common mud contaminants, particularly calcium and chloride.It improves the

mud cake quality effectively

PHYSICAL PROPERTIES

APPLICATION

This product applies for several of water-based mud systems in deep section.
It can provide filtration control at temperatures approaching 400°F（205°C）in water-based drilling fluids. It can replace basic filtration polymers that lose their ability to control HTHP filtration rates at elevated bottom hole temperatures.
 
ADVANTAGES
Reduces fluid loss at temperatures approaching 400°F（205°C）
Does not increase viscosity
Functions in most water-based drilling fluids
Solubilizes readily in water
Maintains filtration control in the presence of contaminants of calcium, magnesium and solids.
 
SAFETY
Avoid contacting with eyes, skin and clothing. Otherwise, wash with a flush of water. Refer to Material Safety Data Sheet (MSDS) for complete handling and hazard data.
