... increasing H2S partial pressure from 10 bar to 15 bar. However, given the significant fall in sour fracture toughness in high H2S partial pressure, the continued resistance to crack initiation is surprising and lacks an obvious explanation. For downhole casing design for sour service, there are generally two...
