Swedish oil firm Lundin Petroleum has upgraded reserves on the Norwegian North Sea Edvard Grieg field following a development drilling campaign.
The drilling programme, consisting of 14 development wells, was completed under budget by the Rowan Viking jack-up drilling rig.
It has led to a 47% increase of the best estimate gross ultimate recovery to more than 300 million barrels of oil equivalent.
Edvard Grieg started production in late 2015.
Lundin is the operator with a 65% working interest. The partners are OMV with 20% and Wintershall with 15%.
Lundin chief executive Alex Schneiter said: “Edvard Grieg is a key asset for Lundin Petroleum. I am very pleased with the performance of the field on all fronts and convinced that we will eventually see the gross ultimate recovery grow to over 300 MMboe.
“The exciting tie-back opportunities in the area have the potential to double the volumes produced through Edvard Grieg, allowing us to keep the facilities full for many years to come.”
