Abstract

Published literature, service experience, and experimental data for galvanic corrosion in oil and gas production are reviewed and discussed. Data are presented in forms that can be used as aids for formal specifications, design criteria, and inspection requirements to help prevent galvanic corrosion failures: Emphasis is placed on downhole and wellhead applications, and oil and gas production equipment for carbon dioxide (sweet) and hydrogen sulfide (sour) environments. Particular attention is given to the effects of galvanic coupling on the noble metal and resulting failures. Galvanic corrosion in seawater environments is briefly reviewed as it pertains to seawater handling, offshore platforms, and subsea completions.
