Zusammenfassung:This invention provides zinc-free aqueous brine compositions. These zinc-free aqueous brine compositions have a density of about 1.71 kg/L (14.3 pounds per gallon) to about 1.89 kg/L (15.8 pounds per gallon), and a true crystallization temperature of about ?6.7?C (20?F) or less, and comprise water and two or more inorganic bromide salts, where the inorganic bromide salts include calcium bromide and cesium bromide. Processes for forming these zinc-free aqueous brine compositions are also provided.
