案例分享 Wintershall Drills 13,330-ft Well with 3,281-ft Lateral in 70 Days Using KLA-SHIELD System, Neuquén Basin
Enhanced-polymer water-based drilling fluid system provides excellent wellbore stability for challenging shale play, Argentina.
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.
KLA-HIB shale inhibitor is used in water-based drilling fluids like KLA-SHIELD drilling fluid to prevent water uptake.
Advantages
- Improved cuttings recovery
- Compatible with high-pH, highly dispersed water-based drilling fluids
- Minimum effect on rheological properties when added to freshly mixed fluids or fluids with very low reactive solids content
- No negative effect on fluid loss control when added to highly dispersed low solids systems
- Compatible with most ROP enhancers, including DRILZONE ROP-enhancing antiaccretion additive
