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, R1 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group, and R2 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group.
Claims18
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;
- R1 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group;
- and
- R2 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl 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 R1R2XCCOOH, wherein:
- X is a halogen;
- R1 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group;
- and
- R2 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group.
A method comprising:
- providing an acidic fluid comprising an aqueous-base fluid, an acid, a corrosion inhibitor, and a precursor to a compound that corresponds to a formula R1R2XCCOOH, wherein:
- X is a halogen;
- R1 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group;
- and
- R2 comprises at least one group selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C1-C20 oxyalkyl, and a C6-C20 aryl group;
- allowing the compound that corresponds to the formula R1R2XCCOOH to generate from the precursor;
- and
- contacting a metal surface with the acidic fluid.
