Oil refiners such as Marathon Petroleum and Valero stand to benefit as renewed Ukrainian drone strikes on Russian refineries look bullish for crack spreads. A drone reportedly hit Kirishi's KINEF refinery again just as it was preparing to restart after months of repairs. KINEF is one of Russia's largest refineries, processing about 20 million tons of oil a year, roughly 6.6% of the country's refining capacity. x.com
