Exceptional Ekofisk

The Ekofisk field in the North Sea.

09/06/2021 This is the 50th anniversary of the Ekofisk field starting up, making Norway an oil-producing nation. And what an adventure it's been.

Over these 50 years, the fields on the Norwegian shelf have collectively produced oil and gas valued at a dizzying NOK 16,000 billion.

Ekofisk has been – and remains – an important contributor to this. It's a fantastic story of bright minds and smart methods, which in many ways illustrates Norwegian petroleum history.

Great resource utilisation 

"The Norwegian Petroleum Directorate congratulates operator ConocoPhillips and the licensees on achieving yet another milestone. Ekofisk must be one of the finest examples of maximum resource utilisation through improved recovery measures," says Director General Ingrid Sølvberg of the Norwegian Petroleum Directorate.

Ekofisk was originally scheduled to shut down in 1997. Water injection, which started in the late 1980s to improve recovery, made a strong contribution toward extending production by more than 30 years so far.

"Increasingly better utilisation and development of technology could make it possible to continue production from Ekofisk for decades to come. The first field on the Norwegian continental shelf could also be one of the last," says Sølvberg.

Value creation

On Ekofisk, the values come from a reservoir 3,000 metres below the seabed. More than three billion barrels of oil have been produced so far from the 300-metre oil column here. If the licensees are able to increase the recovery rate by a few more percentage points, this will have a substantial impact on value creation from Ekofisk.

Without the water injection, less than 20 per cent of the oil in Ekofisk would have been produced. Based on the current plans, the operator plans to extract more than half of the original oil in the reservoir.

Today marks the 50th anniversary of prime minister Trygve Bratteli celebrating the start of test production from Ekofisk.
