Lundin Norway has started drilling on 16/4-10 exploration well on the Fosen prospect, 27km south of the Edvard Grieg field.
The company is drilling the well to test the hydrocarbon potential and reservoir properties at Jurassic sandstones level, located on the southern flank of the Utsira High, west of the South Viking Graben in the North Sea.
Fosen prospect is expected to contain gross unrisked hydrocarbon resources of 192 million barrels of oil equivalents (Mboe).
The well is planned to be drilled to a depth of 2,500m with the semisubmersible drilling unit Island Innovator.
The drilling of the well is expected to be complete in around 50 days.
With a 40% working interest, Lundin Norway is the operator of PL544.
Lime Petroleum Norway and Bayerngas Norge are the other partners with each 30% stake.
In December, Lundin Norway discovered oil in the Rolvsnes prospect in offshore Norway.
The Rolvsnes exploration well is located in PL338C licence south of the Lundin Petroleum-operated Edvard Grieg field in the central North Sea.
Lundin carried out extensive data acquisition and sampling in the reservoir and also performed a production test (DST), which achieved a production rate of 265 barrels of oil per day through a 36in / 64in choke.
