DNO ASA and OKEA ASA have exchanged shares in two prospects offshore Norway, with drilling expected to start soon in both.

DNO will pick up 10% of a production license, PL 1119, including the Mistral prospect in the Norwegian Sea, just south of the Åsgard area. OKEA will receive a 10% interest in PL1109, which contains the Horatio prospect.
