Russia's seaborne oil product exports dropped 33.3% on a daily basis in July from June and 54.7% from the same month a year ago to 3.93 million metric tons, as Ukrainian drone attacks led to unplanned maintenance at key domestic refineries, according to industry sources and Reuters calculations.
A number of Russia's major refineries were hit by drone strikes in recent months, leading to a fall in oil processing as well as lower fuel production and export volumes.
