Since May, Libyas oil production has seen a phenomenal bounce-back, but a dip in output reported on 21 September has underlined the fragility of the recovery and could foreshadow bigger declines to come.
On 14 September, Libyas National Oil Corporation (NOC) announced it was pumping at a rate of 870,000 barrels a day (b/d), up from less than 100,000 b/d in May, and said it was targeting a rate of more than a billion b/d by the end of the month.
This is now looking unlikely. Figures released a week later showed that production fell between 14-21 September, dropping to just 700,000 b/d.
The main driver behind the decline was the closure of Libyas large Sharia oil field due to security concerns, after the nearby Zawiya refinery was hit by a rocket during a militia battle.

Production at the field resumed on Monday. This should help push Libyas production rate higher once again, but the fields closure has highlighted a problem that may dog Libyas oil sector over the coming months.
As the country sinks deeper into the chaos of war, its badly defended oil infrastructure is becoming increasingly susceptible to shutdowns.
Since Libyas eastern rebels lifted their blockade of the countrys biggest oil terminals in July, the vast majority of the ports and oil fields have been controlled by NOC.
NOC is aligned with the House of Representatives, Libyas elected parliament, which is based in the eastern town of Tobruk.
Over the coming months, the NOCs control of Libyas oil assets could be challenged by the General National Congress (GNC), a rival parliament that currently holds sway in Tripoli and has apopointed its own oil minister.
A tussle between the two rival parliaments would prove highly disruptive for production, making it increasingly unlikely that Libya will see output close to pre-revolution levels of 1.6 million b/d anytime in the near future.
