LONDON – Neptune Energy has submitted its plans for two subsea tiebacks to the Gjøa semisubmersible platform in the Norwegian North Sea.
These will be on theDuva (ex-Cara) field, discovered in August 2016 in license PL 636, 6 km (3.7 mi) northeast of the Gjøa field and 12 km (7.4 mi) from the platform; and the Gjøa P1 segment in the northern part of the Gjøa field in PL153. Water depth is around 360 m (1,181 ft).
Neptune expects production to start in late 2020/early 2021. It estimates combined recoverable resources at 120 MMboe, with peak production of 54,000 boe/d.
Duva will have three wells - two oil producers and one gas producer, and potentially a further oil well. These will be connected to a four-slot subsea template, with production sent to the platform for processing and export.
Neptune has applied for exemption from a plan of development and operation for the Gjøa P1 segment redevelopment and this is already covered by the Gjøa field development plan.
Erik Oppedal, Projects & Engineering Manager for Neptune Energy in Norway, said: “We have worked closely with our partners and suppliers to find concepts that both utilize existing infrastructure and maximise the value in the fields.
“The execution of the projects will take place in parallel and will thus create synergies and reduce the cost for both developments.”
Other partners are Petoro, Wintershall, OKEA, and DEA.
