Final phase of Duva development project commences
Published by Nicholas Woodroof,
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 2500 m, 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.
Neptune Energy’s Director of Projects & Engineering in Norway, Erik Oppedal, said: “This is the final phase of the Duva development project, and we are currently working to accelerate the start-up date. An efficient drilling campaign forms an integral part of achieving this. Duva will?both?increase production and extend the?operational?life of our operated?Gjøa?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 3Q21 and will add approximately 25 000 boe/d to the Gjøa facility.
The subsea works associated with Duva were successfully completed in 2020, with the four subsea trees installed in March 2021, successfully overcoming significant challenges presented by the COVID-19 pandemic.
The Duva oil and gas field was Neptune’s first discovery in the Norwegian North Sea, a strategically important area supporting the company’s growth. It is located 14 km northeast of the Gjøa field, at a water depth of 360 m.
