Polyamine shale stabilisation
Polyamine-based inhibitor selection for reactive shale and clay in water-based muds.
How it is used
Amine-based shale inhibitors are used to limit clay hydration and swelling. Selection should account for the formation, base-fluid chemistry and interactions with other components of the drilling fluid.
Application areas
- Reactive shale and clay formations
- Water-based drilling-fluid inhibition programmes
- Applications with hydration-related cuttings or bit-balling concerns
Formulation considerations
Quaternary polyamine, alkylamine and hydroxylamine approaches can be considered. Confirm grade selection against the complete mud system.
What we need to select a grade
- Shale mineralogy or representative cuttings
- Water chemistry and full mud formulation
- Temperature, inhibition objective and compatibility test requirements
Product data and handling
Request the current technical data sheet and safety data sheet for the proposed grade. Confirm dosage, compatibility, handling and supply requirements before use.
