The Kuibyshev oil refinery, owned by Russian oil company Rosneft, suspended crude oil processing on June 10 following a drone attack.

According to Ukrinform, Reuters reported this, citing two sources.

Both primary crude distillation units at the refinery – CDU-4 and CDU-5 – were shut down after the strike caused damage and fires at the facility.

Sources told the news agency that each of the affected units has a processing capacity of approximately 10,000 tons (73,000 barrels) per day.

The Kuibyshev refinery is part of Rosneft’s Samara refining hub, which also includes the Novokuibyshevsk and Syzran refineries.
