Anhydrite can be hydrated to gypsum under near-surface conditions (∼100 m), but gypsum has also been observed at depths >1067 m (Amadi et al., 2012). Anhydrite conversion to gypsum is a consequence of changes in water content caused either by changes in the weight of the overburden (Murray, 1964, West, 1964) or from sediment …

Abstract. Alkali in surfactant flooding can sequester divalent ions and reduce surfactant adsorption. When the alkali is sodium carbonate and anhydrite (or gypsum) is present, the anhydrite will dissolve and precipitate as calcium carbonate. An anhydrite level of only 0.1% in the rock is enough to retard the breakthrough of a 1% sodium …
