Drone attacks that damaged Saudi Arabia’s East-West oil pipeline pushed Brent to its weekly high on September 15, representing a 2.9% increase from the previous session. Prices later declined to the weekly low after Saudi Arabia announced plans to route additional crude through Oman and the Strait of Hormuz, easing concerns over potential disruptions to Saudi oil supplies.

The end of a strike at France’s Dunkirk LNG terminal, however, contributed to the weekly price low recorded on Thursday.
