The installation of the subsea pipelines and umbilicals for the Nova project has been completed in the Norvegian North Sea. The pipelines, umbilicals and tie-in systems will tie the Nova field back to the nearby Gjøa platform, which will process and export the hydrocarbons and provide injection water and lift gas for pressure support.
This completes a summer of significant subsea activity for the Nova project, which began in May with two templates being installed on the seabed at 370 metres water depth, confirms the plan to start production in 2021.
Nova is located in the Norwegian North Sea, 120 kilometers northwest of Bergen. The expected recoverable reserves from the field are around 80 million barrels of oil equivalent (boe), of which the majority will be oil.
Partnership: Edison Norge AS (15%), Wintershall Dea (operator 45%), Capricorn Norge AS (fully owned subsidiary of Cairn Energy PLC) (20%), Spirit Energy Norge AS (20%).
Location: about 120 kilometres northwest of Bergen and approximately 17 kilometers southwest of the Gjøa platform in the Norwegian North Sea.
Water depth: 370 metres
Estimated reserves: 80 million barrels of oil equivalent (BOE)
Development solution: Nova is being developed as a subsea tieback connecting two templates to the existing Gjøa platform which is operated by Neptune Energy. Gjøa will process the production fluids and provide water injection and gas lift to the Nova field. A dedicated Nova module will be lifted onto Gjøa in 2020. Oil from Nova will be transported from Gjøa through the Troll Oil Pipeline II to Mongstad, associated gas will be exported via the Far North Liquids and Associated Gas System (FLAGS) pipeline to St Fergus in the UK, supplying the European energy market.
The use of existing infrastructure enables a cost-efficient extraction of the resources in the reservoir at 2,570 meters below sea level and extends the economic lifetime of the existing infrastructure.
