Sodium Bromide(Liquid/Solid)

Sodium bromide (NaBr) is a white, crystalline salt that is highly soluble in water and commonly supplied as solid or concentrated brine (liquid)

areas of application

  • In the oil and gas industry, sodium bromide (NaBr) is used to formulate high-density completion fluids, which play a critical role in well control, formation protection, and efficient wellbore operations.
  • Formation pressure → choose required fluid density → dissolve solid NaBr in water → get high-density clear brine → pump brine into wellbore → hydrostatic column pressure ≥ formation pressure → prevents influx/blowout and supports borehole wall.

Other Fields

  • Photography: reacts with silver nitrate to form light-sensitive silver bromide in films and papers; also used in developers to reduce fogging.
  • Medicine: intermediate in producing sedatives and some diuretics.
  • Chemical industry: starting material for other bromine compounds, dyes, and fragrances. brine reducing damage.
