Kuwait has agreed with neighbour Saudi Arabia to resume oil production at the jointly operated Khafji field, the Opec member state’s acting oil minister said, weeks before oil producers are set to agree a global output freeze.

Output at the joint Khafji field will be small and introduced gradually, Anas Al Saleh told reporters in the Kuwaiti parliament, without giving the date of the restart or planned production figures. The Khafji field was shut in October 2014 for environmental reasons, having been producing between 280,000 and 300,000 barrels per day (bpd).
