TOP INTEGRITY CHALLENGES: OIL AND GAS SURFACE FACILITIES

摘要

This article summarizes a comprehensive survey conducted by the Research & Development Center (R&DC) of Saudi Aramco to understand top corrosion damage mechanisms experienced by its operating onshore surface facilities. Particular focus was placed on environmentally assisted cracking (EAC), namely hydrogen-induced cracking (HIC), stepwise cracking (SWC), stress corrosion cracking (SCC), and sulfide stress cracking (SSC). The survey identified hydrogen-related damage (in particular, HIC and SWC) and general corrosion--including sulfidation--as the most frequently reported ("top") integrity damage mechanisms followed by coating failures and carbon dioxide (CO_2) corrosion. Corrosion mitigation and inspection methods employed by these facilities were also identified.
