ZOD-UHIB is a kind of liquid polyamines, specifically designed as a shale inhibitor providing excellent shale inhibition and limiting cuttings dispersion. ZOD-UHIB acts as a clay hydration suppressant by reducing the space between clay platelets so that water molecules will not penetrate and cause shale swelling. In addition to its outstanding shale inhibition, ZOD-UHIB also minimizes the accretion potential and consequently BHA balling.
