Analysis of satellite imagery indicates that the October 30 Ukrainian drone attack on Russia's Novosibirsk refinery was one of the most damaging attacks on a Russian refinery this year. Significant damage was detected in the AVT-9 and AVT-11 crude refining units, a hydrodiesel treatment unit, two nearby unidentified facilities and parts of the refineries' tank farm. The actual effect on refining capacity still needs to be determined.
