The company has extracted 48% of the oil on Tordis and 38% of the oil on Vigdis, which is 300 million more barrels that was expected when the developments were planned.
The Norwegian oil operator said that it is likely to produce more oil.
Additionally, new four-dimensional seismic has been collected, which gives the company a much better basis for finding the best possible location of new wells.
The company said that the Tordis and Vigdis license has already secured the drill rig Bideford Dolphin until 2014.
In addition to drilling on Vigdis North-East, which is currently at the planning stage, it will drill new wells on the fields.
