Sodium Sulfate (Na2SO4) - Structure, Properties, and Uses

Sodium sulfate ( Na2SO4) is the sodium salt of sulfuric acid. Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na 2 SO 4 .10H 2 O has been known as Glauber's salt or mirabilis. Na 2 SO 4 .7H 2 O is transformed to mirabilite when it is cooled.

Scale problems in production - PetroWiki

Jan 15, 2018· Seawater has a high-sulfate content; formation waters often have high-barium contents. Mixing these waters results in barite deposition. If this mixing/precipitation occurs within the reservoir far removed from a vertical wellbore, there will generally be little impact on the production of hydrocarbons.

Barium - Wikipedia

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high chemical reactivity, barium is never found in nature as a free element.. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3), both insoluble in water.
