ABSTRACT:
A hydrochloric acid acidizing composition for treating a subterranean formation penetrated by a well bore to increase the production of desired materials (e.g., hydrocarbons) therefrom that includes a corrosion inhibitor for protecting both ferrous based alloy surfaces (e.g., low alloy steel surfaces) and titanium based alloy surfaces associated with the treatment from corrosion by the acid. The corrosion inhibitor includes an effective amount of a first inhibitor component for inhibiting corrosion of ferrous based alloys, the first inhibitor component including at least one chemical reducing compound, and an effective amount of a second inhibitor component for inhibiting corrosion of titanium based alloys, the second inhibitor component including at least one source of molybdate ions such as sodium molybdate. A method of treating a subterranean formation penetrated by a well bore to increase the production of desired materials therefrom is also provided.
