TYPICAL PHYSICAL PROPERTIES

Description
LIGNOMUL, oxidized lignite is a naturally occurring material used to reduce fluid loss and deflocculate water-base muds. LIGNOMUL is a partially soluble additive which provides thin, low-permeability filter cakes. It 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 lignosulfonates. 
It can be used in virtually any water-base fluid.

Applications
LIGNOMUL may be used for rheology and filtration control in all water based muds. It is especially effective at stabilizing the properties of muds exposed to high temperatures and contaminants such as CO2 and calcium. LIGNOMUL is especially effective when treating cement contamination. It reduces the high viscosity and pH of cement-contaminated muds and reacts with calcium to lessen the contaminating effects. 

Recommended Treatment
Normal treatments of LIGNOMUL range from 1-8 lb/bbl (2.85 to22.8 kg/m2. Lignomul requires additional caustic soda to increase pH. Lignomul is most effective in mud systems with an alkalinity range of 9-11.
