Paper Number: SPE-174191-MS
... content in the produced water is calculated using the most sensitive ions, e.g., barium, sulphate, boron, magnesium, etc. Barium and sulphate are reactive ions, that is to say they can react with each other and deposit downhole as seawater sweeps the reservoir from the injection towards the producing well...
