Applications
Leonardite has become an important production asset for a number of industries, thanks to its unique characteristics. Here at Leonardite Products, we deal predominantly with Agriculture, Oil Field and Foundry applications.
Oil Field Applications

Oil Field

In the oil field, Leonardite is better known as “Lignite” and is predominantly used in water - based drilling mud. The colloidal and soluble properties of "Lignite" help in fluid loss control, serve as clay deflocculants and improve filter cake quality. "Lignite" can be blended with caustic soda, and because of its unique organophilic properties Leonardite, or "Lignite", can also be modified for use in oil-based drilling fluids.

As a fertilizer enhancement, Leonardite improves a crop’s ability to absorb nutrients, resulting in faster growth, healthier and higher yields.
