  86. 86. ©2015–HervéBaron HERVE BARON Sour service What is Sour service?
  87. 87. ©2015–HervéBaron HERVE BARON Sour service What is Sour service?  Fluids containing water + a certain amount of H2S  The concentration of H2S above which the service is considered sour is specified in NACE MR0175 for Upstream (oil & gas production) applications and in NACE MR0103 for Downstream (Refinery) applications.
  88. 88. ©2015–HervéBaron HERVE BARON Sour service What happens to materials subject to Sour service?
  89. 89. ©2015–HervéBaron HERVE BARON Sour service What happens to materials subject to Sour service?  Phenomenon: Presence of H2S in the aqueous solution causes the steel to absorb a large amount of H2. The steel is subject to cracking above a critical concentration of hydrogen absorbed. This cracking is called Sulfide Stress Cracking (SSC).  The possible loss of containment resulting from this cracking causes a particularly severe hazard as H2S is fatal in minutes.
