"The licence will be re-registered, and the winner has the pre-emptive rights to acquire the licence," a spokesman for the sale organiser told Reuters. He declined to say how big Gazprom's winning bid was.
However the Interfax news agency quoted a source as saying Gazprom paid 22.3 billion roubles ($773.2 million) for the giant gas field.
Rights to the field, with enough reserves to cover world gas needs for 8 months, were held by a unit of Anglo-Russian company TNK-BP, BP's Russian joint venture.
TNK-BP last year filed to bankrupt its Kovykta subsidiary, Rusia Petroleum, to recover its investments, after failing to win approval to export gas from the field to China.
