Neptune Energy and partners plan to develop the Duva and Gjøa P1 fields as subsea tiebacks to the nearby Gjøa platform in the North Sea, the company said Feb. 21.

Development plans for the fields have been submitted to Norwegian authorities.

“With these development plans, Neptune is entering a period of growth on the Norwegian shelf with a very high activity level,” Odin Estensen, managing director of Neptune Energy in Norway, said in a news release. “We already operate the Fenja development in the Norwegian Sea, with production expected to start up early 2021. Together with the Duva and Gjøa P1 projects, this is a unique project portfolio.”

The Duva Field, formerly called Cara, will be developed with a four-slot subsea template. The field will have three production wells, two oil producers and one gas producer, with the possibility of another oil well, Neptune said in the news release. Neptune is developing the field with partners Idemitsu Petroleum Norge, Pandion Energy and Wellesley Petroleum. Recoverable resources are estimated at 88 million barrels of oil equivalent (MMboe). At maximum production, the field is expected to yield about 30,000 barrels of oil equivalent per day (boe/d) at maximum production, according to Neptune.

The company, on behalf of its license partners Petoro, Wintershall, OKEA and DEA Norway, also submitted an application for exemption from the plan of development and operation for the Gjøa P1 Segment Redevelopment Project because it is included in the development plan for the Gjøa Field. Neptune said the project is considered “further development and extension of the Gjøa Field focusing on increased exploitation.” P1’s recoverable resources are estimated at 32 MMboe, and the field is expected to produce about 24,000 boe/d at peak.

First production for both projects is expected in late 2020 or early 2021.
