SDF - Lignite Powder

Lignite Powder is a naturally occurring material used to reduce fluid loss and deflocculates water base mud. Lignite Powder is a partially soluble additive which provides thin, low permeability filter cakes. It is an excellent emulsifier for oil in water emulsions as wells a secondary deflocculated and is especially effective in high-temperature applications.It performs exceptionally well in dispersed system as a synergistic additive with lingo sulphonates.It can be used in virtually any water base fluid. Lignite Powder may be used for rheology and filtration control in all water-base muds. It is especially effective at stabilizing the properties of muds exposed to high temperature and contamination such as CO2 and calcium. Lignite Powder is especially effective when treating cement contamination. It reduces the high viscosity and pH of cement contamination muds and reacts with calcium to lessen the contaminating effects.
