LIGNEX is a specially processed lignite which contains sodium humate as its basic ingredient.
LIGNEX possesses excellent filtration control properties in sodium based weighted mud systems at elevated temperatures. It also imparts the same qualities to salt water/sea water muds. It is very effective deflocculant and shale stabilizer in all types of water base mud. Further more LIGNEX is also an excellent emulsifier of oil in water at high bottom-hole temperatures. It is thermally stable up to 200°C and above
