Statoil has started oil production at Oseberg Delta 2 field in the Norwegian North Sea.
Statoil operates the filed with a 49.3% interest. Petoro, Total and ConocoPhillips hold 33.6%, 14.7% and 2.4% respectively.
Tied back to the Oseberg Field Centre, the field is expected to produce approximately 77 million barrels of oil during an estimated life of 20 years.
The first phase includes three oil producers and two gas injectors. The field has a capacity for eight wells.
An earlier two-well development from an exisiting template has been producing oil from the Delta terrace since 2008.
The Oseberg Delta reserves are 3,100m below the seabed.
Statoil vice-president for fast-track development projects in development and production in Norway Arild Dybvig said: "Delta 2 is an important element in extending the lifetime of Oseberg.
"It provides a good example of how we can make lesser discoveries profitable by using existing infrastructure while it is still available."
The Oseberg field centre includes three platforms, Oseberg A, B and D, linked to each other with bridges, in the southern part of the field, and the Oseberg C platform.
Gas export began from the Oseberg field centre in October 2000. Oil from the Oseberg area is transported via the Oseberg Transport System to the Sture terminal.
The gas is transported to market through the Oseberg Gas Transport pipeline and into the Statpipe and Vesterled systems via the Heimdal Gas Centre.
