Calcium Chloride vs Calcium Bromide Brine: Density and Selection Guide
Zinc Bromide / Calcium Bromide High-Density Brines
What are clear brine fluids?
Clear brine fluids are solids-free salt solutions used for well completion and workover. Being free of suspended solids, they protect the producing formation from plugging.
Density ladder
Operators step up density using different salts: NaCl to about 10 ppg, NaBr to 12.5 ppg, CaCl2 to 11.6 ppg, CaBr2 to 14.2 ppg, and CaBr2/ZnBr2 blends beyond 19 ppg.
Formulation basics
Select the lowest-cost salt system that meets density and crystallisation temperature limits, then confirm compatibility with the formation water and completion hardware.
Frequently Asked Questions
What density range do clear brine fluids cover?
From about 8.4 ppg with sodium chloride up to over 19 ppg with calcium bromide and zinc bromide blends.
Why are clear brines solids-free?
Suspended solids can plug the producing formation, so clear brines use dissolved salts only to avoid formation damage.
