LONDON – Neptune Energy has started production from the Duva development in the northern Norwegian the North Sea.
The field was discovered in September 2016, when it was named Cara. According to Neptune the formation had been assessed as "dry" 15 years earlier, but proved to contain significant quantities of oil and gas.
Norway’s parliament approved the plan for development and operation in July 2019.
Duva has been developed as a subsea installation with three oil producer wells and one gas producer, tied back to the Gjøa semisubmersible platform via a 9-km (5.6-mi) subsea pipeline.
To maximize efficiency, Neptune executed the project in parallel with the P1-Gjøa development, which started production this February.
Odin Estensen, managing director in Norway, said Duva came onstream below budget thanks to strong collaboration with the partners and key suppliers.
Duva is 14 km (8.7 mi) north-east of Gjøa in a water depth of 340 m (1,115 ft), with estimated reserves of 71 MMboe, of which 56% is gas. At peak it will add around 30,000 boe/d to production through the Gjøa facilities.
Erik Oppedal, projects and engineering director in Norway, added that the field should produce for around 10 years, helping to lower production costs per barrel at the platform.
