Faroe Petroleum said it expects to drill the Brasse East well later this year after agreeing to book a rig.
Faroe said the Transocean Arctic semi-submersible rig would drill Brasse East off Norway in the fourth quarter.
Aberdeen-headquartered Faroe is the operator of Brasse East, with a 50% stake. The only other project partner is Point Resources.
A successful well campaign could add 31million barrels of oil net to Faroe’s portfolio.
Brasse was discovered in 2016 to the south of the Wintershall-operated Brage field.
Faroe chief executive Graham Stewart said: “I am pleased to announce the addition into our 2018 exploration drilling programme of the Brasse East exploration well, which brings the total number of exploration and appraisal wells planned for the year to six.
“The Brasse development programme continues apace as we work towards concept selection by year end.
“If successful the Brasse East well could contribute significant additional hydrocarbons, thereby potentially adding further value to this attractive flagship development project.
“Meantime we await results of the ongoing side-track and potential flow testing operations at the Fogelberg field.
“We are also preparing for drilling of the exciting, high impact Faroe-operated Rungne exploration well, our next exploration well, scheduled to spud in late summer.”
