Industrial Grade Lignite Powder is a partially soluble additive that provides thin low permeability filter cakes accompanied with low fluid loss. Lignite Powder controls rheology and reduces fluid loss, extends temperature limits, emulsifies oil, reduces flocculation and stabilizes water base drilling fluids. Lignite Powder improves filter cake by reducing its permeability and reduces HTHP fluid loss. Lignite Powder is especially effective in high temperature applications and in dispersed systems as a synergistic additive with lignosulfonate. Industrial Grade Lignite Powder can be used in any water base fluid and is apt for thinning and filtration control purpose in water based mud.
