Three traders said Urals supplies via the northern spur of the Soviet-built Druzhba (Friendship) pipeline to Poland and Germany will decrease to around 2.5 million tonnes (590,000 barrels per day) in July from 2.85 million tonnes in June.
Of this, Polish refineries will get 200,000 tonnes less than last month, sales to Germany are set to decline by around 150,000 tonnes.
Rosneft is set to cut its Urals flows to Germany, where it owns stakes in several refineries, by around 100,000 tonnes from June.
At the same time, supplies of Rosneft and Tatneft via the southern spur of the pipeline to Czech Republic will amount to 350,000 tonnes after the flows dried up in June due to refinery maintenance.
Traders also said Russian oil exports to Slovakia and Hungary will remain stable this month. Rosneft, Tatneft and Transneft, Russia’s oil pipeline monopoly, did not reply to requests for comment.
