Sodium Bromide – Applications in oil and gas exploration. Sodium Bromide (NaBr), a salt is used alone or in a combination with sodium chloride or zinc bromide to form clear workaround and drilling fluids with densities of 8.4-12.5 lbs/gal. It is monovalent and is therefore one of the preferred salts (brines) for drilling into a reservoir.
