Organophilic Lignite
Camp Shinning organophilic lignite is an amine treated lignite. As filtration control additive in oil- base systems, black lignite is designed for high temperature filtration control in oil based drilling fluids and synthetic-base systems with good thermal stability and compatibility, effectively controlling filtrate loss, reducing costs.
lignite powder uses to replace asphalt or gilsonite to control fluid loss in any synthetic-base drilling fluid system,and is compatible with other additives.
