Algeria's state-owned energy giant Sonatrach confirmed an incident at its Arzew refinery early Thursday morning, stating that the situation has been brought under control.
The company reported that the event occurred at 02:30 local time (01:30 GMT) and emphasized that there were no injuries or fatalities among staff.
The Arzew refinery is a critical node in Algeria's downstream energy infrastructure, processing crude oil into refined products for domestic consumption and export.
While Sonatrach has not yet disclosed the specific cause of the incident or the extent of any production downtime, the immediate containment suggests the disruption may be limited.
Traders will be monitoring for updates on operational status and potential output cuts in the coming hours.
This development arrives against a backdrop of heightened sensitivity to global refining capacity.
