Abstract:
A method and system for inhibiting corrosion of a surface in a well including introducing a composition into the well, the composition comprising an acidic medium and Dihydrogen (ethyl) [4-[4-[ethyl(3-sulphonatobenzyl)amino] (4-hydroxy-2-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium), contacting the metal surface with the composition, and inhibiting corrosion of the metal surface with the Dihydrogen (ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)amino](4-hyodroxy-2-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene] (3-sulphonatobenzyl)ammonium).

Claim (Index 20):
The composition of  claim 19 , wherein the corrosion inhibitor intensifier comprises potassium iodide, amino trimethylene phosphonic acid, bis(hexa methylene triamine penta (methylene phosphonic acid), diethylene triamine penta(methylene phosphonic acid), ethylene diamine tetra(methylene phosphonic acid), hexamethylenediamine tetra(methylene phosphonic acid), 1-hydroxy ethylidene-1,1-diphosphonic acid, 2-hydroxyphosphonocarboxylic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid, methylene diphosphonic acid, a derivative thereof, a salt thereof, or any combination thereof.
