Researchers from the Tomsk Polytechnic University told state news agency RIA Novosti they used a special optics system to reveal boundaries for 10 oil deposits in parts of Krasnoyarsk Territory.
Geology Associate Professor Valery Rostovtsev told the news agency there is evidence some fields may be quite large in terms of reserves.
"One of them is possibly comparable with the Yurubcheno-Tokhomo field," he said. RIA Novosti estimates that field may contain as much as 365 billion barrels of oil.
Russian oil company Rosneft said it would start production at the Yurubcheno-Tokhomo field by 2016. The report offered few details about long-term development plans for the fields.
Russia ranks second in the world in terms of oil production, with an estimated 9.8 million barrels of oil per day produced in 2011.
