Giant Russian oil pipeline operator Transneft expects to see almost 100,000 barrels a day more come through its export terminals.
A final export schedule report shows a projected growth in December of 3% or 86,400 barrels a day from November figures, from sea-borne supplies.
Exports from Novorossiysk will reach 3.72 million tonnes in December, down 6.3% a day from the initial November export plan, industry sources say.
December crude oil supplies from Primorsk, Russia's largest Baltic Sea oil terminal, will reach 6.3 million tonnes, or 1.49 million barrels per day (bpd), against 1.44 million bpd in November.
December crude exports via Kozmino, the eastern terminus of the East Siberian-Pacific Ocean (ESPO) pipeline, will total 100,000 tonnes and supplied by Russia's largest oil producer Rosneft.
