Used in oil and gas drilling as a component of high-density brine fluids to control wellbore pressure and prevent blowouts. Its high solubility in water allows for the creation of dense solutions that stabilize the drill site. Also employed in completion and workover fluids due to its ability to minimize formation damage and maintain hole stability. In some cases, it serves as a source of bromide ions in chemical synthesis and industrial processes. Additionally, used in water treatment and as a drying agent in certain specialized applications.
