Libya's largest oilfield saw its end-of-month crude shipment volumes cut by more than half, pushing the country's September crude exports down to a three-month low.
Tanker tracking and shipping data show that Libya's September crude exports stood at 1.22 million barrels per day, slightly below August's 1.23 million barrels per day.
The three-month moving average of crude exports, however, moved in the opposite direction, rising by 11,000 barrels per day to approximately 1.28 million barrels per day, the highest level since records began in 2015.
A pipeline at the Sharara oilfield was shut down by an armed group, halving the field's output to 127,000 barrels per day on September 21; production returned to normal by the end of the month.
In early September, two smaller oilfields also briefly suspended production.
Crude supply volumes to Mediterranean buyers fell back from August's record high.
Italy is the largest importer of Libyan crude, with imports of 420,000 barrels per day last month, accounting for approximately 34% of Libya's total crude exports, the lowest share in nearly two years.
Crude exports to Northern Europe rebounded from 19,000 barrels per day in August to 90,000 barrels per day in September.
Crude sold to Asian buyers edged down to 117,000 barrels per day; transatlantic crude volumes shipped to the Americas rose to their highest level year-to-date.
