Operator Det Norske Oljeselskap has spudded an exploration well on the Heimdalshoe prospect, on production licence 494, in the Norwegian North Sea.
Joint venture partner Fortis Petroleum revealed the jack-up Maersk Giant had spudded exploration well 2/9-5S on Monday.
"We are pleased to announce the spudding of this very exciting well in the southern part of the Norwegian North Sea,” Fortis chief executive Michael Haagaard said in a statement on Wednesday.
“The well marks Fortis’s first exploration well and is the first of three wells we expect to drill in 2014.”
The Heimdalshoe prospect lies in 65 metres of water, roughly 34 kilometres west of the Valhall field.
The 2/9-5S well is expected to take between 60 and 125 days, contingent on a discovery, and will target the hydrocarbon potential in the primary Upper Jurassic target with a prognosed total depth of up to 3542 metres.
Det Norske holds a 30% operating stake in PL 494, with partners Dana Petroleum (24%), Fortis Petroleum (16%), Spike Exploration (15%) and Tullow Oil (15%).
