Norway-based Det Norske has reduced production from the Alvheim FPSO due to an electric fault that occurred in the high voltage drive motor for a gas export compressor.
The company plans to cut average production for 2015 from about 62 000 barrels of oil equivalents per day to about 59 000 – 60 000 barrels of oil equivalents per day.
The Alvheim FPSO, operated by Det Norske with 65% working interest, will run at reduced volume of production for a period of about four weeks.
Det Norske plans to replace the motor.
Production at present is optimised within the capacity of the other gas export compressor.
The company said that decrease in production will not impact the reserves of the fields that are connected to the Alvheim FPSO or Det norske’s expected production for 2016.
Other partners in Alvheim are ConocoPhillips with a 20% interest and Lundin Norway with a 15% interest.
The Alvheim field is located in the central part of the North Sea close to close to the UK sector and consists of the Kneler, Boa and Kameleon discoveries.
Alvheim is estimated to contain total recoverable resources of about 90 million barrels of oil equivalents.
Production from the field commenced on 8 June 2008. It comprises the resources in licences 088 BS, 203 and 036 C.
