Anhydrite Gypsum Contamination

21.06.2022Anhydrite and gypsum are calcium sulfate compounds (CaSO4) which are sometimes encountered while drilling. Gyp is calcium sulfate with water of crystallization (CaSO4 2H2O), while anhydrite is the anhydrous (waterless) form of calcium sulfate (CaSO4). These may occur as thin stringers or massive beds.

Anhydrite and gypsum

In this regard, Murray (1964) has pointed out that gypsum formed at the surface will inevitably dehydrate to anhydrite on burial (depth of conversion dependent on the prevailing T, P and groundwater salinity). In turn, on uplift and contact with dilute groundwaters, anhydrite will rehydrate to gypsum.
