LABORATORY INVESTIGATIONS OF SILICATE MUD CONTAMINATION WITH CALCIUM

The silicate-based drilling fluid is a low solids KCl/polymer system with the addition of soluble sodium or potassium silicate to enhance inhibition and wellbore stability. Silicate-based drilling fluids exhibit remarkable shale and chalk stabilizing properties, resulting in gauge hole and the forma...
