Russia increases the volume of marine exports and oil refining Russian oil exports increased despite an increase in the volume of refining at the refineries. International shipments rose to 3.65 million barrels per day in the four weeks to Nov. 1, according to tanker shipment data compiled by Bloomberg. This is 60,000 b/s more than the figure in the corresponding period until October 25. In the week to Nov. 1, 38 tankers loaded 27.8 million barrels of Russian oil, according to ship tracking data and industry reports. The previous week the figure was 27.12 million barrels on 37 ships. Supply volumes rose by 100,000 per day last week to an average of 3.97 million per day, the highest in five weeks. On average, the crude value of Russian oil supplies rose over the past four weeks, hitting a three-week high of $2.66 billion per week. The increase in total supplies and the 16th consecutive increase in Pacific Expo oil prices were offset by a decline in Ural oil prices.
