Statoil starts production from Gjoa, plans development hub in the northern North Sea
08.11.2010 + + + The Gjøa oil and gas field developed by Statoil (NYSE:STO) began production on November 7, opening the way for more activity in the northernmost part of the Norwegian North Sea.
The Gjoa development consists of five subsea templates tied back to the semisubmersible production platform. Another three subsea units will be connected with the Vega gas satellite comes on stream in the near future. The Gjoa platform is located 45 kilometers from land at the northernmost end of hte North
Sea. Oil from Gjøa will be piped to Mongstad via the Troll II line. Gas will be piped through the British Flags system to St Fergus in the UK.
Recoverable reserves in Gjøa are put at 82 million barrels of oil and condensate and 40 billion cubic metres of gas. Vega is expected to yield 26 million barrels of condensate and 18 billion cubic metres of gas.
Development Hub
“We envisage that its facilities can make this field a hub for developments in this area,” says Øystein Michelsen, executive vice president for Exploration & Production Norway.
“Oil and gas are set to flow from Gjøa for at least 15 years to come,” says Michelsen. “However, we’ve seen that technology advances and the recovery factor constantly improves.
“There are also openings for further development in the area, so the field’s platform and infrastructure has been designed for a producing life of at least 30 years.
Power
The Gjøa platform is the world’s first production floater to receive its power from land. Electricity is transmitted through a 100-kilometer cable from Mongstad north of Bergen.
This reduces carbon emissions on the field by about 210,000 tonnes per year. It is only the second Norwegian offshore installation to be powered in this way, after Troll A.
Mostly Norwegian
The project has demonstrated that Norwegian industry is competitive, with such companies responsible for 70% of the project.
Work on fabricating the platform and its associated infrastructure began in 2007. Costing some NOK 40 billion, the Gjøa/Vega project has been completed on
schedule. “This is a profitable investment, both for the licensees and for Norway,” emphasises Digre.
GDF Suez holds 30 percent interest in the project and serves as the production operator. Statoil holds 20 percent interest and served as the development operator. Petoro holds 30 percent interest; Shell has 12 percent; and RWE Dea holds the remaining 8
percent.
