North Sea Gjøa, Edvard Grieg tiebacks get the go-ahead
STAVANGER, Norway – Neptune Energy and Lundin Norway have received approvals for three North Sea development projects.
The Duva and Gjøa P1 developments, according to Neptune, have total recoverable resources at 120 MMboe.
First production is due in late 2020. At peak, Duva should deliver 30,000 boe/d and Gjøa P1 24,000 boe/d.
Neptune submitted its plans for the developments this February.
Duva’s calls for a four-slot subsea template tied back to the Gjøa semisubmersible platform for processing and export. The field will have two oil producer wells and one gas producer, with the potential to add a further oil well.
As the P1 segment was already covered by the original development plan for the Gjøa field issued in 2007, Neptune submitted an application for exemption from a plan of development and operation (PDO).
TechnipFMC will implement the subsea tiebacks via the Neptune Subsea Alliance Agreement, with Odfjell responsible for drilling and Rosenberg WorleyParsons for topsides modifications on the Gjøa platform.
Erik Oppedal, projects and engineering manager for Neptune Energy Norge, said: “The approval of the plans allows us to start this summer with the first step in our parallel project execution– the subsea installation of the Duva template.”
Together with the ongoing installation activities for the Fenja development in the Norwegian Sea, this demonstrates the company’s ability to execute developments with pace and efficiency optimising resources and accelerating time to production.”
Norway’s Ministry of Petroleum and Energy has approved Lundin Norway’s PDO for the Solveig field, the first tieback to the company’s Edvard Grieg platform on the Utsira High in the North Sea.
First oil from Solveig Phase 1 in license PL359 should flow in early 2021 building to a peak of 30 MMboe/d.
Lundin estimates the capital cost at $810 million, with a breakeven of less than $30/boe. It plans three horizontal oil production wells and two water injectors, to be drilled by Seadrill’s semisub West Bollsta.
Rosenberg WorleyParsons is modifying the Edvard Grieg field facilities with TechnipFMC supplying the subsea system under a lump sum EPCI contract.
