Product Description
It is a liquid polyamine additive and used as primary shale inhibitor. Shale inhibitor is achieved by preventing water uptake by clays, and by providing superior cutting integrity.
Application
The Shale HS shale inhibitor is a liquid additive that act 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. The SHALE HS shale inhibitor provides outstanding shale inhibition and minimizes dilution rates.
SHALE HS chemistry additionally provides a buffered pH in the 9.0 - 10.0 range, eliminating any required additions of caustic soda or potassium hydroxide.
It is important to monitor cutting condition at the shakers during drilling operations. Cuttings should be firm and dry inside. Sticky and balled-up cuttings may indicate insufficient inhibition from a low SHAL HS concentration.
