Longboat Energy said on Wednesday that operator PGNiG has signed up the Odfjell Drilling semi-submersible rig Deepsea Yantai to drill the Copernicus exploration well in the Norwegian Sea.

Drilling is expected between June and September next year on the prospect, located in the Utgard High in the Voring basin region.

Copernicus is estimated to contain gross mean prospective resources of 254 million barrels of oil equivalent, with further potential upside bringing the total to 471 million boe.
