Shale Stabilising Additives
View product family →Understanding Shale Hydration and Inhibition
Reactive shale may absorb water, swell, soften or disperse when exposed to water-based drilling fluids. This article explains the causes of shale hydration, its operational effects and why inhibition is considered in mud-system design.
