CT CZKLIG is a specially formulated modified lignite also Known as Causticized Potassium Lignite compound manufactured from high humic acid Lignite compatible with all water base mud systems and developed specially for use in potassium based mud systems


It may be used for rheology and filtration controls in potassium base mud and for helping maintain a constant PH. It is especially effective at stabilizing the property of mud 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 mud


  • It contributes the potassium ion to the mud systems and improves rheological properties.

  • It reduces formation and reservoir damage by limiting the migration of clay.

  • It Reduces washouts and improves well caliper by base exchange

  • It helps to control water sensitive shale.

  • It aids in controlling temperature stability of mud by reducing flocculation and gelation.

  • It improves rheological properties of water based system
