Alkalinity and pH Control

Potassium hydroxide is a strong alkali commonly known as potash (KOH). It is used in place of caustic soda (NaOH) to control the alkalinity of potassium-based muds, or where potassium ions are preferred as a shale inhinitor over the sodium ion

Magnesium oxide (MgO) is an alkaline material used to establish alkalinity up to pH 10.0 in both fresh water and brine systems. Magnesium oxide does not form precipitates when added to calcium-based brines

Sodium bicarbonate is used to precipitate soluble calcium in water based drilling fluids

Soda ash (sodium carbonate) is used to precipitate soluble calcium and control alkalinity in water-based drilling fluids

Caustic soda (Sodium hydroxide) is a widely used chemical to control pH and alkalinity properties in all water-based drilling fluids

A multi-purpose weak organic acid which is widely used in oilfield completion and stimulation operations.

The MIL-LIME alkalinity control agent from Baker hughes is a calcium source and to provide alkalinity in both water based and oil based drilling fluids
