Oil and gas have been struck at the Engie-operated Cara well in the Norwegian North Sea.
The Norwegian Petroleum Directorate (NPD) said the project partners will weigh up whether to link this discovery to existing infrastructure at Gjøa field, six kilometres away.
Engie has the operatorship and 30% of the licence, Tullow Oil has 20%, with Idemitsu Petroleum on 30%, and Wellesley Petroleum on 20%.
NPD said the well encountered a gas column of about 50 metres and an oil column of about 60 metres.
Preliminary estimation of the size of the discovery is between 4.3million and 11million standard cubic metres of recoverable oil equivalents, an NPD spokesperson said.
The Transocean Arctic carried out the drilling programme.
