Most of the refiners are getting the crude grades that they want, the sources said on Thursday, adding that there was no request from state-owned oil company Saudi Aramco for them to change grades.

Saudi Aramco's oil processing facilities at Abqaiq and Khurais were attacked by missiles and drones on Sept. 14, shutting down 5.7 million barrels per day (bpd) of its production, or more than 5% of global supplies.

At the height of the disruption, Saudi Aramco asked customers to switch their crude grades for loadings in the second half of September and early October and pushed back crude and oil product deliveries to customers by days.

Top Saudi oil officials have said that the kingdom's output has bounced back to 11.3 million bpd and the country was on track to regain its maximum oil production capacity of 12 million bpd by the end of November.
