The gas field is owned by a consortium made up of Gazprom, Total and Statoil.
Gazprom's original plan called for production, estimated at 23.7 billion cubic metres of natural gas a year, to begin in 2013.

Gazprom announced in July that it might delay the launch of the gas project to reflect market conditions.
The Shtokman field holds natural gas reserves estimated at 3.8 trillion cubic metres.
Located in the Barents Sea, it is seen as being technically challenging to exploit.
