Statfjord Celebrates 30 Years on Stream

Thirty years after the Statfjord field started production, one of the largest oil fields in the North Sea has now become a gas field.

“On 24 November 1979 we brought one of the North Sea’s largest oil fields on stream,” said Øystein Michelsen, executive vice president for Statoil’s Exploration & Production Norway business area. “Today we operate a field where 65% of the total output is gas. A whole new era in Statfjord’s history has begun.”

Through the Statfjord late life project, Statoil has made massive alterations and investments in recent years to prepare the three Statfjord platforms for production of gas and oil with lower pressure.

Big changes are also going on in the subsurface. For many years focus has been on keeping up the pressure in the reservoir to press out as much oil as possible. Today it is all about reducing the pressure in the reservoir to get out the remaining gas.

Reducing the pressure causes the gas to bubble out of the remaining oil volumes. This process has now started in the reservoirs 2.5 kilometres below the Statfjord platforms.

“Statfjord has been an important pioneer and building block in the development of Statoil and of Norway as an oil nation,” said Michelsen.

“Thirty years after production start-up Statfjord remains a pioneer. This is the first big field we are converting from oil to gas production. The experience we gain from Statfjord will be crucial when other oil giants like Oseberg and Gullfaks undergo similar changes.”

The Statfjord late life project increases the recovery rate from the Statfjord field to 66% for oil and 71% for gas.

The total value creation from Statfjord is now worth as much as $213.3b. This is equivalent to half of the assets in the Norwegian Government Pension Fund.
