CT CZLIG is a specially formulated and chemically modified compound of lignite. It is a Partially Soluble Additive that provides thin low permeability filter cakes accompanied with low fluid Loss


Causticized Lignite may be used for rheology and filtration controls in water base mud’s and for helping maintain a constant pH. It is especially effective at stabilizing the property of mud’s exposed to high temperatures and contaminations.
It is especially effective in high temperature applications and in dispersed systems as a synergistic additive with lignosulfonates. It can be used in any water base fluid.
It is used for thinning and filtration control purpose in water base muds


  • It improves filtration control.

  • Reduces viscosity and gel strengths.

  • Extends the temperature limitation of water base fluids.

  • Functions effectively in a wide range of Muds even in the presence of contaminants

  • Improves filter cake by reducing its permeability.

  • It controls rheology and reduces fluid loss, extends temperature limits, emulsifies oil, reduces flocculation and stabilizes water base drilling fluids

  • Reduces HTHP fluid Loss
