Neptune Energy pulls off Kyrre gas discovery near Gjøa field in North Sea


In a major development in the North Sea’s Norwegian sector, Neptune Energy and its partners have announced a new gas discovery at the Kyrre prospect and confirmed significant volumes for the Ofelia appraisal well, both located in the PL 929 license, near the Gjøa field.

Neptune Energy has successfully completed the Ofelia appraisal well, 35/6-4 ST2, in the Agat formation, revealing an estimated recoverable volume of 16-33 million barrels of oil equivalent (mmboe). Additionally, the 35/6-4 A side-track drilled into the Kyrre prospect has led to a new gas discovery, with estimated recoverable resources of 11-19 mmboe of gas. These discoveries collectively contribute to a total recoverable volume of approximately 27-52 mmboe.

Odin Estensen, Neptune Energy’s Managing Director for Norway and the UK, highlighted the significance of these discoveries in strengthening the company’s position in the Greater Gjøa Area, an essential growth hub for Neptune Energy in Norway. The discoveries are considered for a potential fast-track, low-cost, and low-carbon development, aligning with the company’s sustainability goals.

The Ofelia Agat and Kyrre discoveries, located about 23 kilometers north of the Neptune-operated Gjøa platform, are being evaluated for development as tie-backs to Gjøa. Neptune is also assessing the possibility of jointly developing these discoveries with the Gjøa Nord (Hamlet) oil and gas discovery, which has estimated recoverable volumes between 8-24 mmboe.

The Gjøa platform, notable for its low carbon intensity, is electrified with power from shore, producing less than half the average carbon intensity of fields on the Norwegian Continental Shelf. This emphasizes Neptune Energy’s commitment to sustainable energy production.

Steinar Meland, Neptune’s Director of Exploration & Development in Norway, commented on the high reservoir quality in the Kyrre discovery, which allows for high production rates. He also mentioned the preparation for several other exploration opportunities in the area, including the Cerisa well, expected early next year.

The wells 35/6-4 ST2 & 35/6-4 A were drilled by the Deepsea Yantai, a semi-submersible rig operated by Odfjell Drilling and owned by CIMC. The partners in this venture include Neptune Energy (operator, 40%), Wintershall Dea (20%), Pandion Energy (20%), Aker BP (10%), and DNO (10%).

This discovery by Neptune Energy marks a significant advancement in the energy sector, particularly in the context of sustainable oil and gas production in the Norwegian Continental Shelf.
