KLA-STOP NS additive is a liquid polyamine shale inhibitor used in polymer-base drilling and drill-in fluids. Shale inhibition is achieved by preventing water uptake by clays, and by providing superior cuttings integrity. KLA-STOP NS additive effectively inhibits shale or gumbo clays from hydrating and minimizes the potential for bit balling. KLA-STOP NS inhibitor can be added directly to the mud system with no effect on viscosity or filtration properties.
