Abstract

Inhibiting or preventing corrosion of metallic components downhole may be accomplished by introducing neutralization media into a wellbore in the proximity of downhole metallic components, where the neutralization media comprises magnesium and where the method further includes subsequently contacting the neutralization media with a potentially corrosive environment comprising at least 5 volume % water, where the water has a pH of less than 11. This contacting activates the neutralization media with the water thereby releasing magnesium ions, and the magnesium ions react with hydroxyl ions of the water to give magnesium hydroxide in an amount effective to raise the pH of the water present to be between about 8 and 12 thereby inhibiting or preventing corrosion of metallic components downhole.
