Patent ID: 7994101

Claim:
A method comprising: providing a metal surface within a well bore that penetrates a subterranean formation; and contacting the metal surface with a treatment fluid comprising an aqueous base fluid, an acid, a corrosion inhibitor, and a corrosion inhibitor intensifier composition comprising a surface active corrosion inhibitor compound that corresponds to a formula: PR 1 R 2 R 3 , wherein R 1 , R 2 , and R 3 are chosen from the group consisting of C 1 -C 20 alkyl, cycloalkyl, oxyalkyl, and aryl groups, and R 1 , R 2 , and R 3 may or may not be equal; wherein the corrosion inhibitor is selected from the group consisting of: an acetylenic compound, cinnamaldehyde; dicinnamaldehyde; p-hydroxycinnamaldehyde; p-methylcinnamaldehyde; p-ethylcinnamaldehyde; p-methoxycinnamaldehyde; p-dimethylaminocinnamaldehyde; p-diethylaminocinnamaldehyde; p-nitrocinnamaldehyde; o-nitrocinnamaldehyde; o-allyloxycinnamaldehyde; 4-(3-propenal)cinnamaldehyde; p-sodium sulfocinnamaldehyde; p-trimethylammoniumcinnamaldehyde sulfate; p-trimethylammoniumcinnamaldehyde; o-methylsulfate; p-thiocyanocinnamaldehyde; p-(S-acetyl)thiocinnamaldehyde; p-(S-N,N-dimethylcarbamoylthio)cinnamaldehyde; p-chlorocinnamaldehyde; α-methylcinnamaldehyde; (β-methylcinnamaldehyde; α-chlorocinnamaldehyde; α-bromocinnamaldehyde; α-butylcinnamaldehyde; α-amylcinnamaldehyde; α-hexylcinnamaldehyde; α-bromo-p-cyanocinnamaldehyde; α-ethyl-p-methylcinnamaldehyde; p-methyl-α-pentylcinnamaldehyde; cinnamaloxime; cinnamonitrile; 5-phenyl-2,4-pentadienal; 7-phenyl-2,4,6-heptatrienal; and mixtures thereof; and, wherein corrosion of at least a portion of the metal surface is inhibited.
