Following the completion of expansion work on the ultra-sour gas Shah field in May 2023, production has been ramped up. Occidental, which owns 40% of the Shah project and which operates the field in conjunction with ADONC Sour Gas, reported in July that it had achieved record output at Shah, with gross gas sales reaching 722 million scfd in Q2 2023 (equivalent to 1.1 billion scf/d of raw gas, which is 23% H2S and 10% CO 2 ). The expansion has taken processing capacity at Shah to 1.45 billion scf/d and forms part of the UAE’s plans to achieve gas self-sufficiency by the end of the decade. The expansion was conducted by Saipem, who were awarded a $510 million contract in 2021 to expand output from 1.3 billion scf/d to the current 1.45 billion scf/d. Work was completed two months ahead of schedule, according to Occidental.
