A acidic salt, ZnBr2, which is used to prepare dense, clear (solids-free) brine for well completion and workover operations. The density of saturated zinc bromide is approximately 20 lbm/gal, but its pH is low and can cause acidic corrosion and handling p

A neutral zinc salt, ZnCO3, which can be used as a sulfide scavenger in water-base muds. Zinc carbonate is less soluble than zinc basic carbonate and perhaps slower to react with sulfide ions. Treatment level is about 0.1 lbm/bbl per 50 mg/L sulfide ion (

n: (ZnCI2) a very soluble salt used to increase the density of water to points more than double that of plain water. Normally added to a system first saturated with calcium chloride.
