Neptune Energy and its licence partners have made a new oil and gas discovery at the Calypso exploration well (6407/8-8 S), located in production license PL938 in the Norwegian Sea.
Following drilling to a vertical depth of 3,496m, well 6407/8-8S encountered an estimated 8m thick gas column and 30m thick oil column in a 131m thick Garn Formation sandstone reservoir.

The well has been drilled using the Deepsea Yantai semi-submersible rig, which is owned by CIMC and operated by Odfjell Drilling.
As per the preliminary estimates, the discovery holds between one and 3.5 million standard cubic metres of recoverable oil equivalents. This corresponds to six to 22 million barrels of oil equivalent (boe).
Neptune Energy Norway and the UK managing director Odin Estensen said: “We actively explore in areas close to existing infrastructure. These near-field discoveries allow for low cost and low carbon developments.
“Initial analysis of Calypso indicates commercial potential. Together with our partners in the Calypso licence, we will now study options to effectively develop the discovery using nearby infrastructure.”
The Calypso discovery marks Neptune’s third find on the Norwegian Continental Shelf in the last six months.
Neptune Energy Norge operates the PL938 with a 30% stake. It’s partners include Pandion Energy (20%), Vår Energi (20%), and OKEA (30%).
OKEA Subsurface senior vice-president Andrew McCann said: “The Calypso discovery shows that there is still potential to discover new resources in this mature area and is a good example of OKEA’s strategy to explore for new resources near our producing assets.”
The Calypso discovery is located within one of the core areas of Neptune, 14km north-west of the Draugen field and 22km north-east of the Njord A platform.
The licence partners plan to assess the discovery’s commerciality by studying options for development using existing infrastructure, including the OKEA-operated Draugen field.
