A Rosneft spokeswoman declined to comment.
Rosneft is already active in another Latin America country,Venezuela, while its chief executive Igor Sechin, a long-timeally of Russian President Vladimir Putin, is keen on expandingthe company's global reach.
Rosneft is in a process of acquiring Anglo-Russian oilproducer TNK-BP for $55 billion, the largest such dealin Russian corporate history. It has signed deals withExxonMobil, Statoil and Eni to tapoffshore oil and gas in Russia's Arctic region.
