Saudi Aramco has delayed light crude oil loadings to PetroChina for October delivery by about 10 days, Reuters reported.

The Saudi oil giant has committed to supplying the same amounts and grades of crude oil.

Aramco reportedly told some of its clients that vessel loading has resumed following disruptions caused by recent drone attacks on oil facilities in Khurais and Abqaiq.

The Saudi Oil Supply Planning and Scheduling (OSPAS) department said that loading operations were in progress.

Attacks on Aramco’s largest Saudi oilfields in Khurais and the world’s biggest crude processing facility at Abqaiq have partially halted the company’s production, reducing Saudi oil output by more than half, specifically around 5.7 million barrels per day (b/d), which makes for about 5% of global oil supply.
