HERCUL-EZ is a proprietary additive that is used in conjunction with bentonite based drilling muds. With proper formulation, the system will produce a unique drilling fluid with excellent shear thinning characteristics. At low shear or at rest, the fluid will gel and allow for suspension of large cuttings, yet thins immediately under pumping conditions. At rest, HERCUL-EZ fluid looks and behaves like a semisolid, but when sheared, even slightly, will revert back to a thin, almost water-like consistency. HERCUL-EZ is designed to be compatible with CETCO bentonite-based drilling fluids. NSF/ANSI/CAN Standard 60 Certified.
