OSLO - Norway's oil and gas producer StatoilHydro said on Friday that production at its Statfjord C platform in the North Sea was slowed to minimum levels due to a water leak that has shut down satellite fields.

There is a leak of produced water, including some which contains oil, StatoilHydro spokesman Oistein Johannessen said. It comes from the satellites of Statfjord C, so there is minimum production at Statfjord C and the satellites have been closed down.

He said the size of the leak was not yet known and declined to be drawn on the incident's impact on production volumes.

Satellite fields Statfjord East, Statfjord North and Sygna are tied into the Statfjord C platform, according to the Norwegian Petroleum Directorate (NPD).

The three satellite fields together produce some 34,000 barrels of oil per day, according to NPD data. The entire Statfjord field produces some 47,000 barrels per day, as well as smaller amounts of natural gas and natural gas liquids.
