COMPLETION AND WORKOVER FLUIDS
Zinc Bromide
Zinc bromide (ZnBr₂) is a heavy, colorless salt that can be a solid (crystals) or a dense liquid when dissolved in water (brine). It makes very heavy, clear brines used mainly in deep, high-pressure oil and gas wells.
areas of application
- Offshore: used as clear brine in deep sea wells for completion, workover and sometimes drilling to hold very high formation pressure safely.
- Onshore: used the same way in land wells needing very heavy clear fluid for pressure control and to avoid formation damage.
- Often blended with CaBr₂/CaCl₂ to fine-tune density and properties.
- Primarily applied in oil & gas high-density drilling/completion fluids, and in radiation shielding and specialty chemical uses.
Other Fields
- Battery electrolytes (zinc–bromine batteries / flow batteries)
- Organic synthesis and catalysis
- Radiation shielding and specialty glasses
- Pharmaceutical intermediates
- Flame retardants and polymer additives
