Profile: Winter Mud Co. specializes in drilling mud. Our products line includes BLACKNITE®, C-MUL™, COASTALUBE®, COASTAL SPOT® and EK 2000® DEGREASER. Our BLACKNITE® is patented and most successful borehole stabilization and HPHT fluid loss control product. The BLACKNITE® contains multisized particles in a proprietary blend containing coupled gilsonite, glycol, & surfactant that actually strengthens the well bore minimizing washout and spurt loss. It is a thick black liquid with a specific gravity of 1.08 and available in 55-gallon (208 L) drums, 550-gallon (2,082 L) bulk containers and disposable tote tanks. Our COASTALUBE® is a drilling fluid lubricant for water-based drilling systems, utilizing a polyalphaolefin (PAO) synthetic hydrocarbon base. The COASTALUBE® enhances the drilling mud in low pressure situations by coating the formation and drill string as well as acting as a boundary layer lubricant in high temperature and pressure applications. It is readily dispersible and compatible with salt water based systems.
