STAR HIB® SF is a high-performance shale inhibitor is a proprietary non-ionic amine designed for use in water-based (WBM) drilling fluids. It is used in formations that contain reactive clays such as smectite and mixed layer illite/ smectite. Unlike conventional shale inhibitors, STAR HIB® SF does not require KCl or other salts for inhibition. It does not contribute to salinity or electrical conductivity of the drilling fluid or filtrate.
