Method of inhibiting corrosion in acidizing wells |
| abstract |
Corrosion inhibitor additives are added directly to an aqueous acid solution used in acidizing subterranean formations. The additives comprise a bismuth compound, a quaternary compound, and a surfactant. The corrosion inhibitor is free of toxic Sb and acetylenic compounds. |
