Abstract
At least in aspect, the invention provides methods that include a method comprising: contacting a metal surface with an acidic fluid comprising an aqueous base-fluid, an acid, a corrosion inhibitor, and a corrosion inhibitor intensifier composition comprising an intensifier compound that corresponds to the following formula: wherein R1 is a methyl or ethyl group, and R2 is H or an alkyl, aryl, alkyl aryl, alkylthio aryl, alkyloxy aryl, halogenated aryl, phenyl, alkyl phenyl, alkylthio phenyl, alkyloxyphenyl, or a halogenated phenyl group.
Claims15
A method comprising:
- contacting a metal surface with an acidic fluid comprising an aqueous base-fluid, an acid, a corrosion inhibitor, and a corrosion inhibitor intensifier composition comprising an intensifier compound that corresponds to the following formula:
- wherein R1 is a methyl or ethyl group, and R2 is H or an alkyl, aryl, alkyl aryl, alkylthio aryl, alkyloxy aryl, halogenated aryl, phenyl, alkyl phenyl, alkylthio phenyl, alkyloxyphenyl, or a halogenated phenyl group.
A method comprising:
- introducing an acidic fluid into a well bore via a metal conduit, wherein the acidic fluid comprises an aqueous-base fluid, an acid, a corrosion inhibitor, and a corrosion inhibitor intensifier composition comprising a compound that corresponds to a formula
- wherein R1 is a methyl or ethyl group, and R2 is H or an alkyl, aryl, alkyl aryl, alkylthio aryl, alkyloxy aryl, halogenated aryl, phenyl, alkyl phenyl, alkylthio phenyl, alkyloxyphenyl, or a halogenated phenyl group.
