KLA-HIB

Amine-based shale inhibitor

KLA-HIB amine-based shale inhibitor is a liquid polyamine shale inhibitor for water-based drilling fluids that inhibits reactive shale by preventing water uptake. Effective inhibition of clay hydration minimizes the potential for bit balling.

It is used in applications where levels of inhibition obtained with other amine additives such as KLA-STOP liquid polyamine shale additive are not required.

KLA-HIB can be used as the primary hydration inhibitor in KLA-SHIELD enhanced-polymer water-based drilling fluid system. Alternatively, it can be used as an additional inhibitor in gypsum or lime systems.
