Abstract
A method of reducing corrosion within a wellbore includes placing a wireline including a perforating gun in a wellbore, the wellbore extending through an earth formation and including a casing extending through the earth formation, the wireline including zinc, discharging the perforating gun to form perforations through the casing and in the earth formation surrounding the casing proximate the at least one perforating gun, flowing a fracturing fluid including one or more proppants through the perforations and into the earth formation to open fractures in the earth formation with the one or more proppants, introducing a flushing fluid into the wellbore to displace the fracturing fluid, and flowing a corrosion inhibitor composition into the wellbore and through the perforations with at least one of the fracturing fluid and the flushing fluid. The corrosion inhibitor includes an alkenylphenone, and a substituted 1-azanapthalene.
