Calcium Bromide (CaBr2) Completion and Packer Fluids: A Technical Overview
Calcium Chloride vs Calcium Bromide Brine: Density and Selection Guide
Role of sodium bromide
Sodium bromide, NaBr, CAS 7647-15-6, is a clear-brine salt used alone or blended with sodium chloride and calcium chloride to build solids-free completion and workover fluids in the medium density range.
Density and blending
A saturated NaBr brine reaches around 1.5 g/cm3 (12.5 ppg). It is often paired with NaCl for cost-effective density control where calcium compatibility is a concern.
Advantages
NaBr brines are compatible with many formations and are used where divalent calcium would cause scaling or compatibility issues.
