Corrosion inhibitors are used to protect deepwater facilities against internal corrosive attack. Corrosion can particularly occur in the slug flow regime. In this article, the development and testing of corrosion
inhibitors to protect against slug flow in subsea deepwater locations is described. A testing protocol for corrosion inhibitors that tests for performance in the appropriate flow regime and for compatibility with
process fluids and system facilities is described.
