ABSTRACT:
Of the many methods and compositions provided herein, one method includes 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 a compound that corresponds to a formula R1R2XCCOOH, wherein X is a halogen, R1comprises at least one group selected from the group consisting of a C1-C20alkyl group, a C3-C20cycloalkyl group, a C1-C20oxyalkyl, and a C6-C20aryl group, and R2comprises at least one group selected from the group consisting of a C1-C20alkyl group, a C3-C20cycloalkyl group, a C1-C20oxyalkyl, and a C6-C20aryl group.
