First production from the projects is expected in late 2020 with total recoverable resources estimated to be 120 million barrels of oil equivalent (boe) (maximum production is expected to be respectively 30,000 boe from Duva and 24,000 boe from Gjøa P1).
The fields will be developed through subsea tie-backs connecting two templates to the nearby Gjøa platform, operated by Neptune Energy Norge.
Neptune Energy Norge’s Managing Director Odin Estensen, said: “This is a significant milestone for our business and for the licence partners in Duva and Gjøa. With these plans approved, we remain on track for the successful execution of these important projects. Not only do these developments strengthen Gjøa’s position as a major hub in the northern North Sea, they demonstrate our ambitions to continue growing our business on the Norwegian Continental Shelf.”
On behalf of the licence owners, Neptune Energy submitted development plans for the Duva (PL636) and Gjøa P1 (PL153) projects to Norwegian authorities on 21 February this year.
The Plan for Development and Operation (PDO) of the Duva field was submitted on behalf of the Duva partnership, which consists of Idemitsu Petroleum Norge (30%), Pandion Energy (20%), Wellesley Petroleum (20%) and Neptune Energy (30% and Operator). Duva’s recoverable resources are estimated to be 88 million boe and it’s expected to yield around 30,000 boe per day at maximum production. Developed with a four-slot subsea template, the Duva field will be tied back to the Gjøa platform for processing and export. The field will have three production wells, two oil producers and one gas producer, with the potential for an additional oil well.
As the P1 segment was already covered by the development plan for the Gjøa field, an application for exemption from PDO was submitted on behalf of the Gjøa licence partners, consisting of Petoro (30%), Wintershall (20%), OKEA (12%), DEA (8%) and Neptune Energy (30% and Operator). P1’s recoverable resources are estimated to be 32 million boe and it is expected to yield around 24,000 boe per day at maximum production.
The subsea tie-backs will be delivered by TechnipFMC utilising the Neptune Subsea Alliance Agreement, the drilling operations will be undertaken by Odfjell and topside modifications completed by Rosenberg Worley.
Erik Oppedal, Projects & Engineering Manager for Neptune Energy Norge added: “The approval of the plans allows us to start this summer with the first step in our parallel project execution– the subsea installation of the Duva template. Together with the ongoing installation activities for the Fenja development in the Norwegian Sea, this demonstrates the company’s ability to execute developments with pace and efficiency optimising resources and accelerating time to production”.

About the Duva field (PL 636)
The Duva field is located 6 kilometres northeast of the Gjøa field (12 kilometres from the Gjøa platform). The shortest distance to shore is 35 km. The discovery was made in production licence 636 in August 2016 by drilling well 36 / 7-4.
Licence partners: Neptune Energy Norge (30% and operator), Idemitsu Petroleum Norge AS (30%), Pandion Energy AS (20%) and Wellesley Petroleum AS (20%).
About the Gjøa field (PL 153)
The Gjøa field was discovered in 1989, and a PDO was delivered and approved by the Norwegian authorities in 2007. The field is developed with five subsea templates tied to the Gjøa Semi-Submersible for processing and export. Production started in 2010. Oil is exported by pipeline to Mongstad and gas by pipeline to St. Fergus in the UK. The Gjøa P1 segment is located in the northern part of the Gjøa field.
Licence partners: Neptune Energy Norge (30% and operator), Petoro AS (30%), Wintershall Norge AS (20%) OKEA (12%) and DEA Norge AS (8%).
