Product Description

HYPERHIB^® shale inhibitor is a low-molecular-weight polymer blended liquid containing povidone & polyamine derivative to provide superior inhibition of reactive clay and reduce swelling of sensitive shales exposed to water-based drilling fluids. HYPERHIB^® is the primary shale inhibitor of HIBTEC^® high-performance water-based drilling fluid system. It 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. HYPERHIB^® can also flocculate any dispersed clays or colloidal particles and aids their removal by solids control equipment to achieve shear-thinning properties. HYPERHIB^® is suitable in fresh water, seawater and monovalent brines up to 250°F.

Applications/Functions

• Provides excellent shale inhibition and maximized cuttings integrity
• Reduces accretion potential and consequently bit balling
• Flocculates any dispersed clays or colloidal particles and aids their removal by solids control equipment
• Minimizes dilution rates

Advantages

• Temperature stable up to 250°F but may achieve higher if use oxygen scavengers
• Highly effective in KCl/Polymer water-based drilling fluids
• Environmentally acceptable both onshore and offshore applications
• Directly added into system without impacting viscosity and filtration properties
