Overall oil exports in February from the western ports of Primorsk, Ust-Luga and Novorossiisk are seen at 1.6 million barrels per day (bpd), down from 1.73 million bpd in January's plan, Reuters calculations show. The February figure could go higher, traders said, if recent Ukraine's drone attacks on Russian refineries means more crude is earmarked for export. Russia's Ryazan oil refinery suspended operations after an attack late last week, two industry sources told Reuters. Russia's crude exports via Baltic ports are still curbed due to technical issue in Ust-Luga. The port cut oil loadings by half of capacity in January to a four-year low partly due to technical issues on Transneft's pipeline system.
