The use of corrosion resistant alloys (CRAs) for oilfield applications has expanded greatly in recent years. For the most part, selection of CRAs is based on resistance to corrosive species in the production environment (i.e. H2S, CO2, sulfur, brine). In may cases, however, there are non-production environments to which these materials must also be resistant for either short term or prolonged duration. These environments include: (Stimulation acids, (2) Completions and Workover Fluids and (3) surface and Injected Waters. This paper discussed the requirements and methodology of selection of CRAs for resistance to corrosion and stress corrosion cracking in these non-production oilfield environments. It provides service experience and information obtained through laboratory investigations which identify the critical aspects of each type of environment and the requirements of a sound materials evaluation and selection program.
