Product Overview
Key Features
Federal's oxidized lignite is a naturally occurring material used to reduce fluid loss and deflocculate water-base muds. LIGNITE 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

LIGNITE 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 temperatures and contaminants such as CO2 and calcium. LIGNITE 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. 22.8 kg/m3). Due to their low pH, LIGNITE treatments require additional caustic soda, or an alternative alkaline material, to maintain a consistent pH. A normal ratio is 1 sack of caustic soda for every 4 sacks of LIGNITE. In high-salinity systems, it is preferable to premix the LIGNITE in medium-pH fresh water to enhance dispersibility, then add the premix to the active system. LIGNITE is most effective in mud systems with an alkaline pH in the range of 9 to 11.Normal treatments of LIGNITE range from 1 to 8 lb/bbl (2.85 to 22.8 kg/m3). Due to their low pH, LIGNITE treatments require additional caustic soda, or an alternative alkaline material, to maintain a consistent pH. A normal ratio is 1 sack of caustic soda for every 4 sacks of LIGNITE. In high-salinity systems, it is preferable to premix the LIGNITE in medium-pH fresh water to enhance dispersibility, then add the premix to the active system. LIGNITE is most effective in mud systems with an alkaline pH in the range of 9 to 11.
