Upgrades to Bahrain’s 267,000 b/d Sitra refinery are set to increase its capacity by 113,000 b/d to 380,000 b/d when they finally come online next year. This will cap almost 1.36mn b/d of GCC capacity additions since 2022 following the start-up of Saudi Arabia’s Jazan, Kuwait’s Al Zour and Oman’s Duqm refinery (see table).
