Potassium lignite
Potassium Lignite is a potassium salt of modified lignite, designed specifically for water-based drilling fluids to improve shale inhibition, fluid-loss control, and thermal stability. It is produced by chemically treating natural lignite with potassium compounds to enhance its solubility, dispersibility, and shale-stabilizing performance.
