LONDON- * The International Energy Agency updated its outlook on global refining capacity additions for 2018 and 2019 in its monthly Oil Market Report
* For 2018, the IEA expects an increase of 1.8 million barrels per day of refining capacity, compared with the previous estimate of 1.3 million bpd
* The additional 500,000 bpd comes from several sources: the shutdown of Saudi Arabia's Jeddah refinery is now attributed to 2017, not 2018; the start-up of Turkey's new refinery at Izmir is brought forward to 3Q18 from 2019; Iran's third condensate splitter in the Persian Gulf Star complex is now expected to be completed in 4Q18, versus 2020; minor additions in Iraq totalling 70,000 bpd by end-2018
* For 2019, the IEA expects additions of 1.4 million bpd, down 80,000 bpd from earlier estimates. That is due to the start-up of the 400,000-bpd Jazan refinery in Saudi Arabia and two Chinese petrochemical plants (Hengli Petrochemical, Zhejiang Petrochemical)
* The IEA removed CNOOC's 70,000-bpd addition at the Ningbo Daxie refinery.
