Alkalinity Control

Adjust water-based fluid pH

M-I SWACO provides a suite of additives to control alkalinity in water-based and invert emulsion fluids. These agents may increase or decrease the alkalinity within the drilling fluid. Alkalinity agents help provide fluid stability, improve polymer hydration and performance, and treat out contaminants like cement, carbon dioxide, hardness, and H2S encountered in mix waters or while drilling.
