Statoil, along with its partners Eni Norge and Petoro, has discovered gas in the Nunatak prospect in the PL532 block of the Barents Sea.
Statoil said the gas discovered is considered to be non-commercial.
Gas in rocks of Cretaceous age were discovered while drilling well 7220/5 in the prospect. The well was drilled using the West Hercules rig.
Statoil Norway exploration senior vice president, Gro G. Haatvedt, said: "With Nunatak we tested a new geological play model in the Johan Castberg area and acquired essential data which will be further analysed."
"The Nunatak results do not have any implications for the expectations to the next three wells as these will target other play models," Haatvedt added.
"Whilst it is disappointing to find only gas in Nunatak, we believe in further oil potential in the Johan Castberg area."
Meanwhile, Statoil and its partners have also collected prime data for the Johan Castberg field development studies.
Statoil vice president field development for northern Norway, Erik Strand, Tellefsen said: "Although the well did not succeed in adding resources to the Johan Castberg field development it has given us valuable data to firm up the well and subsea solutions for the Skrugard reservoir."
Nunatak prospect was the first four prospects to be drilled in the Johan Castberg area in 2013, in order to find additional volumes for the Johan Castberg field development project.
After the completion of drilling at Nunatak prospect, the West Hercules rig will be moved to license PL608 to drill the Iskrystall prospect.
Statoil is the operator of PL532 block with an ownership share of 50%, while Eni Norge and Petoro are licence partners of the block with 30% and 20% shares respectively.
