Description
Soda Ash is the common name for Sodium Carbonate (Na2CO3). It is used in water-base muds as a source of carbonate ions to precipitate calcium, increase pH or flocculate spud muds. It is soluble in water and dissociates into sodium (Na) and carbonate (CO3) ions in solution.
Application & FeaturesSoda Ash is primarily used to reduce soluble calcium in water-base drilling muds and makeup waters. Also used to increase pH and flocculate spud muds.
Soda Ash is widely available and an economic source of carbonate ions to precipitate calcium while increasing pH. It effectively removes calcium in most drilling fluids at small treatment levels.
