Tullow Oil has clearance to use the semisub Leiv Eiriksson to drill well 6507/11-11 in PL 591 in 272 m (892 ft) of water in the Norwegian Sea, targeting the Zumba prospect.

Drilling will start either this month or in June, lasting 50 days, possibly extended by a further eight days for testing in the event of a discovery.

Repsol Exploration Norge will engage the semisub Bredford Dolphin to drill the Hagar prospect in 226 m (741 ft) of water in PL 642 in the southern Norwegian Sea. The location is 80 km (50 mi) southwest of the Draugen field, and 65 km (40 mi) west of Smøla.
