Organic corrosion inhibitor package for organic acids |
| abstract |
An acidizing composition useful for treating a subterranean hydrocarbon producing formation and removing scale from oilfield equipment, the composition including: an acid; water; and an effective amount of a corrosion inhibitor composition including: at least one mercapto-compound; and at least one alkoxylated acetylenic alcohol. Also disclosed are methods for removing scale from metal surfaces and for treating a subterranean hydrocarbon producing formation with such an acidizing composition whereby the corrosive effects of the acidizing composition on metal surfaces in contact therewith are reduced. |
