Neptune Energy has commenced drilling the Calypso exploration well in the Norwegian Sea.

The exploration well, 6407/8-8 S, is being drilled by the Deepsea Yantai, a semi-submersible rig, owned by CIMC and operated by Odfjell Drilling. The Calypso prospect is located 14 kms north-west of the Draugen field and 22 kms north-east of the Njord A platform, within the Neptune-operated PL938 Licence.

Calypso is positioned within one of Neptune’s core areas on the Norwegian Continental Shelf. In the event of a commercial discovery, Calypso could potentially be tied back to existing infrastructure.

Neptune Energy’s Director of Subsurface in Norway, Steinar Meland, said: 'Calypso is an exciting prospect and fits our exploration strategy of focusing on opportunities within core areas and near existing infrastructure.'

The reservoir target is the middle and lower Jurassic formations and is expected to be reached at a depth of approximately 2,960 metres.

The drilling program comprises a main-bore (6407/8-8 S) with an optional side-track (6407/8-8 A) based on the outcome of the exploration well.

Partners: Neptune Energy (operator, 30%), OKEA (30%), Pandion Energy (20%) and Vår Energi (20%).
