Operator Neptune Energy and its partners Idemitsu Petroleum Norge, PGNiG Upstream Norway and Sval Energi today announced the safe and successful start-up of production from the Duva development in the Norwegian sector of the North Sea.

Duva was developed as a subsea installation with three oil producers and one gas producer, tied back to the Neptune Energy-operated Gja semi-submersible platform.

To maximise efficiency, Duva was executed in parallel with the Gja P1 development which began production in February this year.

Neptune Energys Managing Director in Norway, Odin Estensen, said: "Duva is an excellent example of a successful fast-track development, with production beginning less than five years after its discovery. Tied back to existing infrastructure, it has been delivered efficiently and under budget through strong collaboration with our partners and key suppliers, and is expected to have one of the lowest CO2 emissions per produced barrel of oil equivalent (boe) on the Norwegian Continental Shelf. 

"The start-up of Duva further strengthens Neptunes position in the northern part of the North Sea, a strategically important growth area for the global business. 

Duva is located 14 km northeast of the Neptune Energy-operated Gja field at a water depth of 340 metres. Estimated total reserves are 71 million boe, of which 56% is gas. It will add approximately 30 kboepd (gross) to the Gja facility at plateau.

Electrified with hydropower from shore, CO2 emissions per boe on the Gja platform are less than half the average on the Norwegian Continental Shelf.

Neptune Energys Projects and Engineering Director in Norway, Erik Oppedal, added: "The Duva field is expected to produce for approximately 10 years and thus contribute to extending the life of the Gja platform. This will help lower Gjas production costs per barrel, adding significant value for licence partners and future tie-backs.
