Teams are working around the clock to bring Iraq’s Baiji refinery back online, after it was recaptured from the jihadist group Islamic State in Iraq and Syria (Isis) in November.

“Engineers are working day and night to repair the refinery,” said Iraq’s Oil Minister Adil Abdul-Mahdi, speaking at the Organisation of Arab Petroleum Exporting Countries (Oapec) conference in Abu Dhabi.

The refinery was seized by Isis on 10 June, during an advance that saw the group take control of large swathes of Iraq, including Mosul, the country’s second city.

Baiji is Iraq’s biggest refinery and was producing 75,000 barrels of oil a day (b/d) when it was shut down.

Isis rigged the refinery with booby traps and mines that had to be removed before engineers could start work.

Abdul-Mahdi said Iraq is currently looking to boost its production of crude as well as increasing its capacity to produce refined products, petrochemicals and fertilisers.

The country produced 3.1 million b/d over 2013, according to UK-based BP’s Statistical Review of Energy.
