Neptune Energy and its partners have discovered hydrocarbons in the Calypso exploration well in the Norwegian Sea.

The Calypso exploration well is located in the Calypso prospect within the PL938 licence. It is situated approximately 14km north-west of the Draugen field and 22km north-east of the Njord A platform.

The well is being drilled using the CIMC-owned Deepsea Yantai semi-submersible rig. The rig is operated by Odfjell Drilling.

In a statement, Neptune said: “Having entered the reservoir, logs proved the presence of hydrocarbons. Additional data gathering of the reservoir will now be considered.”

The firm said the operations are at an early stage in the reservoir section and the partners are yet to confirm the commercial volumes of the hydrocarbons.

Neptune owns an operatorship stake of 30% in the Calypso exploration well. Its other partners are OKEA (30%), Pandion Energy (20%), and Vår Energi (20%).

Neptune and its partners started the drilling programme at the well earlier this month. The programme includes a main-bore (6407/8-8 S) with an optional side-track (6407/8-8 A) based on the exploration well outcome.

At that time, the firm said the Calypso well could be tied back to existing infrastructure in the event of a commercial discovery.

Earlier this year, Neptune Energy selected TechnipFMC to provide technical services for its Norwegian operations.

Under the contract, TechnipFMC is responsible for providing engineering studies and technical services for Neptune Energy.

The scope of work includes installation work and operational support for Neptune’s development projects and producing fields.
