UltraDril Plus
Premium-performance aqueous drilling fluid system
Balanced fluids for performance, economics, and sustainability in challenging drilling environments
Shale inhibitor
UltraHib™ shale inhibitor is an essential component of the UltraDril Plus™ premium-performance aqueous drilling fluid system. A liquid polyamine, it effectively inhibits shale or gumbo clays from hydrating while minimizing the potential for bit balling. UltraHib shale inhibitor enhances drilling performance by preventing water absorption by clays, reducing cuttings dispersion, and minimizing risks related to BHA and bit balling. This shale inhibitor acts as a clay hydration suppressant by intercalating and reducing the space between clay platelets so that water molecules will not penetrate and cause shale swelling. In addition to providing outstanding shale inhibition, UltraHib shale inhibitor minimizes dilution rates.
