Russia needs to supply its own market with enough crude oil to produce motor fuels essential to meet demand in the summer driving season and to replenish supplies ahead of seasonal maintenance.
Russia's August oil shipments from Primorsk, Ust-Luga and Novorossiisk will rise by 9% on a daily basis from July's plan, Reuters calculations show.
Oil loadings from the three western ports in July were revised up by some 0.23 million bpd from the initial schedule, to some 1.8 million bpd after Lukoil, Rosneft and Gazpromneft obtained additional loading slots.
Russia's largest private oil company Lukoil ramped up seaborne exports last month as its supplies to Europe via the Druzhba pipeline are currently suspended.
For August, Russia's offline primary oil refining capacity is seen declining by a third from July to 1.7 million tons, according to Reuters calculations based on data from industry sources.
Russia's oil loadings are also capped by the state's pledge to the OPEC+ group of oil-producing nations to cut output.
