Operator Neptune Energy and its partners announced drilling has begun on four production wells on the Duva field in the Norwegian sector of the North Sea.
The wells are being drilled by the Deepsea Yantai, a semi-submersible rig operated by Odfjell Drilling.
All four wells were pre-drilled and cased off at a depth of 2,500 metres, prior to starting the final drilling campaign.
Duva is a fast-track project being developed as a subsea installation with three oil producers and one gas producer, tied back to the Neptune-operated Gjøa semi-submersible platform.
The Deepsea Yantai is now set to drill the reservoir sections, install the lower completions and execute well clean-up activities. The drilling work is estimated to take around 110 days.
Duva is scheduled to come online in the third quarter of 2021 and will add approximately 25,000 barrels (gross) of oil equivalent per day (boepd) to the Gjøa facility.
