Russia's energy-rich Yamalo-Nenets Autonomous region plans to put up seven oil and gas deposits for auction soon, a deputy head of the regional administration said on Thursday.

The regional government plans to offer five gas deposits of the South Tambeisky block on June 28 and two oil and gas deposits of the Novoportovskoye block in July, Vladimir Vladimirov said.

Vladimirov said the regional government had received bids for the deposits of the South Tambeisky block from gas giant Gazprom and Russia's largest independent gas producer Novatek, adding that bids for the other two deposits were likely to be submitted by Gazprom Neft, the oil arm of Gazprom, and oil and gas company Surgutneftegaz.

The South Tambeisky group of deposits, which was discovered in 1974, is located in the northwest of the Yamal Peninsula. As of early 2008, its category C1+C2 gas reserves stood at 1.256 trillion cubic meters.

The Novoportovskoye oil and gas condensate deposit is located in the Yamal-Nenets Autonomous region. Its recoverable reserves comprise about 265 billion cubic meters of natural gas, about 238 million metric tons (1.7 billion barrels) of oil and about 13 million metric tons of gas condensate.
