Causticised Lignite

Causticised Lignite

Causticised Lignite is a proprietary tannin based product used for controls rheology and reduces fluid loss, extends temperature limits, emulsifies oil, reduces flocculation and stabilizes water base drilling fluid. It is readly soluble over a wide range of temperature and is effective in low concentration without requiring the use of caustic soda.In solution it has an alkaline pH therefore it does not require large caustic additions to maintain a stable pH, SR-CL is a partially soluble additive that provides thin,low-permeability filter cakes accompainied and in dispersed systems as a synergistic additive with lignosulphonates.It can be used in virtually any water base fluid.Normal treatment of SR-CL range from 1 to 10 lb/bbl.In high salinity systems.It is preferable to premix to the active systems. It is most effective in mud system with an alkaline pH in the range of 9 to 10.5.
