 Ukraine's strikes on three Russian refineries reached their target. Seven-day oil refining volumes in the Russian Federation fell sharply to the lowest level in almost two months. The crisis has gripped the Russian industry due to the shutdown of two large refineries at once, as well as serious damage to a third after they were hit by Ukrainian drones. This was reported by the Bloomberg News Agency. Journalists received analytical data, according to which the first week of January showed a serious drop in oil processing to 5.41 million barrels per day, which is 135,000 barrels below the average for most of December. Attacks on oil refining and export facilities have become increasingly destructive in recent weeks, threatening the Russian Federation's ability to supply fuel to foreign and domestic markets. Experts note the success of the strategy chosen by Ukraine to inflict maximum damage on a key area of Russian industry for the Russian budget. Bloomberg emphasises that oil refining has been completely stopped at two large refineries that send their products for export. This refers to the Novotek plant on the Baltic coast and the Tuapse oil refinery of Rosneft PJSC. The oil refinery in Volgograd, which was hit in early February, was also damaged. This is one of the largest oil refineries in the Russian Federation, supplying fuel to both domestic and foreign markets.
