Description
Calcium Bromide (CaBr₂) is a white powdered inorganic salt of 95% purity.

Typical Properties
Appearance: White free flowing powders
Purity: 95%

Features and Benefits
Calcium Bromide is used to prepare solids free workover and completion fluids with densities up to 15.2 lb/gal. It can also be used for packer fluids.

Calcium Bromide is also used to increase the density of various calcium chloride/calcium bromide/zinc bromide blends.

Calcium Bromide brines contribute to formation damage control by stabilizing the water sensitive clays during workover and completion operations.

An exothermic reaction takes place when Calcium Bromide is added to water. This results in an increase in brine temperature. 

Application
Calcium Bromide is utilized to build clear brine workover and completion fluids for formations with pressure gradients ranging from 0.437 to 0.790 psi/ft. 

Limitations
Calcium Bromide brines may cause scale formation when formation waters are rich in carbonate and sulfate ions. This problem is also anticipated in wells producing gas with significant amount of carbon dioxide.

Treatment
Refer to mixing table (Table-1) to obtain the desired density and crystallization temperature. Calcium Bromide is added to fresh water trough the rig hopper while agitating until powders completely dissolve.

Packaging
Calcium Bromide is supplied in 25 kg (55 lb)  moisture-proof, multiwall sacks
