Neptune Energy and its partners have started production from the Duva development in the Norwegian sector of the North Sea.
Duva oil and gas field, in production license 636, was discovered in 2016. The project was granted startup approval by the Norwegian Petroleum Directorate in July (OGJ Online, July 28, 2021).
Duva was developed as a subsea installation with three oil producers and one gas producer, tied back to the Neptune Energy-operated Gjøa semi-submersible platform.
For efficiency, Duva was executed in parallel with the Gjøa P1 development which began production in February (OGJ Online, Feb. 23, 2021).
Duva lies 14 km northeast of Neptune Energy-operated Gjøa field at a water depth of 340 m. Estimated total reserves are 71 MMboe, of which 56% is gas. It is expected to add about 30,000 boe/d (gross) to the Gjøa infrastructure at plateau.
Electrified with hydropower from shore, CO2 emissions per boe on the Gjøa platform are less than half the average on the Norwegian Continental Shelf, Neptune said in a statement released Aug. 23.
Duva is expected to produce for about 10 years and contribute to extending the life of the Gjøa platform, which “will help lower Gjøa’s production costs per barrel, adding significant value for license partners and future tie-backs,” said Erik Oppedal, Neptune Energy’s projects and engineering director in Norway.
Neptune is operator with 30% interest. Partners are Idemitsu Petroleum Norge (30%), PGNiG Upstream Norway (30%), and Sval Energi (10%).
