Kuwaiti oil production dropped by 42,000 barrels a day (b/d) in May according to data collected by the oil and gas research company Energy Aspects.

The drop came as production from the Divided Zone, which is shared by Saudi Arabia and Kuwait, fell to zero.

According to data collected by Energy Aspects, Kuwait’s output dropped to 2.73 million b/d after the Wafra field in the Divided Zone was shut on 11 May.

“All Neutral Zone output remains offline, which may weigh more heavily on Kuwaiti output in June,” the company said in a statement released on 15 June.
