k-Drill® S9

Das Additiv

k-Drill® S9 is a high purity potassium sulphate product (K2SO4) of natural origin, dedicated for use as a chloride free shale inhibitor in water based drilling fluids where chloride salts are restricted. Thus k-Drill® S9 is increasingly being used in on-shore drilling operations, where disposal of chloride salts is regulated.


k-Drill® S9 has a maximum solubility in water of 10 % at 20 °C. It should not be blended with calcium containing drilling fluids in order to prevent Gypsum precipitation.
