Et av de største prosjektene for økt utvinning (IOR) på norsk sokkel skal skje på Snorre-feltet i Nordsjøen. Havbunnsutbyggingen består av seks brønnrammer, hver med fire brønner. Det er planlagt tolv brønner for produksjon og tolv brønner for vann- og gassinjeksjon. Utbyggingen legger til rette for tilknytning av ytterligere brønnrammer. Illustrasjon: Statoil

Snorre PDO approved

The PDO for the Snorre Expansion Project has been approved by the ministry. That means the field will produce for another 25 years.

The Snorre Expansion Project will increase recovery from the Snorre field by almost 200 million barrels and extend the field life beyond 2040. The plan was delivered in 2017 (geo365: “Snorre: Mer olje med IOR”) and has now been approved by the Ministry of Petroleum and Energy.

Snorre Expansion Project is the largest project for improved recovery on the Norwegian continental shelf. The project involves a comprehensive subsea development, upgrading of the Snorre A installation, increased gas injection and gas import for injection, Equinor says in a press release.

51% recovery

The Snorre field was originally estimated to produce until 2011–2014. Now the field life has been extended beyond 2040, and the recovery rate increases from 46 to 51 per cent.

Facts

  • The Snorre field was discovered in 1979 and came on stream in 1992.
  • A giant in the North Sea, Snorre is one of the fields with the largest remaining reserves of Equinor’s oil producing fields on the Norwegian continental shelf.
  • When the PDO was submitted, estimated production was 750 million barrels of oil. Up to now, the Snorre field has produced 1.4 billion barrels of oil.
  • The Snorre field was originally estimated to last until 2011–2014. Now the field is expected to produce beyond 2040.
