Snefrid Nord Gas Discovery, North Sea, Norway
Snefrid Nord gas discovery lies in 1,312m of water in the production licence (PL) 218 of the Norwegian North Sea.
The site is located approximately 6km away from the Aasta Hansteen field (previously Luva).
Statoil Petroleum is the field operator and holds 51% interest in the site, while the development partners include Wintershall Norge (24%), OMV Norge (15%) and ConocoPhillips Skandinavia (10%).
Snefrid Nord is planned to be developed together with the Aasta Hansteen development.
First production from the field is expected to be achieved in late-2019.
Snefrid Nord gas field discovery
Snefrid was discovered in 2015 with the drilling of the 6706 / 12-2 wildcat exploration well, which was conducted as part of Statoil's near-field exploration programme. It was drilled by the Transocean Spitsbergen drilling rig to a depth of 2,754m.
The primary objective of drilling the well was to prove gas in the Nise Formation.
The well penetrated Tertiary and Cretaceous limestones and sandstones, encountering 75m of sandstones of good reservoir quality.
It also encountered a 103.4m gas column and a 6m oil column within the Nise Formation.
The well was not flow tested, however data acquisition and sampling activities were conducted.
Geology and reserves of the Norwegian gas discovery
Snefrid is part of the Vøring area, a large sedimentary basin of the Norwegian Sea.
The field is estimated to contain recoverable reserves of approximately five billion cubic metre of gas.
Snefrid Nord field development details
Snefrid is planned to be developed through a one-well single-slot subsea template, which will be connected to the Aasta Hansteen development through the Luva template.
Development of the field is expected to require an investment of Nkr1.2bn ($143m).
The field is expected to have a productive life of five to six years, and produce four million cubic metre of gas a day at plateau.
Gas produced from the site will be exported onshore via the 480km Polarled gas pipeline.
The project will increase the resource base of the Aasta Hansteen development by 15% and extend its production plateau.
It will also enable complete utilisation of the Polarled pipeline capacity.
Statoil has contracted Aker Solutions and Subsea 7 to supply equipment for the Snefrid Nord development.
The companies previously supplied subsea equipment for the Aasta Hansteen project.
Aker Solutions has been awarded the contract to supply the subsea template, along with a suction anchor mooring and umbilicals.
The subsea template and suction anchor will be manufactured at Aker Solutions' Sandnessjøen office, while the umbilicals are to be manufactured by its Moss office.
Subsea 7 has been contracted to deliver flowlines and spools, and will also be responsible for all the development's subsea installations.
Details of the Aasta Hansteen development
The Aasta Hansteen development includes the joint development of the Luva, Haklang and Snefrid South fields.
It is a strategically important project and is expected to facilitate the tie-up of future field developments.
The site features the world's biggest SPAR platform and is scheduled to commence production in 2017.
The project, together with the Snefrid Norden development, will enable the Polarled pipeline to supply gas to Europe.
