MOSCOW (Reuters) - Russian refining runs fell by 8.4 percent in April compared with March mainly due to maintenance at a number of plants, Energy Ministry data showed.

Russian refineries processed 4.40 million barrels per day (bpd) of crude in April, down from 4.80 million bpd in March.
In year-on-year terms, runs rose by 0.2 percent.
Russian state-controlled oil major Rosneft cut runs at its NovoKuibyshev refinery by a third to around 82,000 bpd due to planned maintenance.
Oil processing at Rosneft’s Kuibyshev plant fell by more than 30 percent to nearly 98,000 bpd.
Russia’s top refiner, Surgut’s Kirishi plant, cut processing by 24 percent to 327,000 bpd.
Moscow refinery almost halved runs to 119,064 bpd with gasoline output down by more than 50 percent to 79,100 tonnes.
The refinery’s main shareholders include Gazprom Neft, the oil arm of Russian gas export monopoly Gazprom, the city of Moscow and mid-sized oil firm Tatnef.
Traders said that lower processing and output of refined products in April could also be due to overstocking in the Russian domestic market with the fuels which prompted oil companies to cut processing to prevent prices from going down.
