Abstract
In a process for the exploration for or the production of crude oil and/or natural gas, wherein metal objects are exposed to a gas for period of time sufficient to produce an aqueous film, a method including introducing a corrosion inhibitor into a fluid in contact with the subject metal under conditions sufficient to introduce the corrosion inhibitor into the aqueous film can be used to prevent excessive corrosion. Useful as the corrosion inhibitor is 2-sulfanylpropan-1-ol, also known as 2-mercapto-ethanol, and 2-mercapto-ethanol substituted with one or two methyl groups, and combinations thereof.
