Detailed Product Description

 Description 

Causticized Lignite is a partially soluble additive that provides thin, low-permeability filter cakes accompanied by low fluid loss. It controls rheology and reduces fluid loss, extends temperature limits, emulsifies oil, reduces flocculation and stabilizes water base drilling fluids In solution, it has an alkaline pH, therefore it does not require large caustic additions to maintain a stable pH.

Application & Features........

Causticized Lignite may be used for rheology and filtration control in water base muds and for helping maintain a constant pH. It is especially effective at stabilizing the properties of muds exposed to high temperatures and contaminations such as calcium.

Causticized Lignite 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.

Causticized Lignite does not require additional treatments with caustic soda. It is most effective in mud systems with an alkaline pH in the range of 9 - 11.
