At a Kremlin news conference, Putin pointed particularly to the Barents Sea's giant Shtokman gas field and the Yuzhnorusskoye field in the northern Russian region of Yamal-Nenets, which could produce dozens of billions of cubic meters of gas a year.
He also cited the reserves of the largely-unexplored East Siberia region.
"The Shtokman deposit is expected to yield as much as 90 billion cu m a year over the next 50 years," Putin said.
Calling East Siberia "a Klondike of energy resources", the president said, "There are enormous resources there, for which there will undoubtedly be a demand."
Putin said that one of Siberia's advantages was its remoteness from the political center. "It is not involved in political intrigues," he said.
