Statoil Gets Green Light for Tyrihans Project
The Norwegian Storting (parliament) has approved the plan for development and operation (PDO) of the Statoil-operated Tyrihans field in the Norwegian Sea.
The project embraces two structures – Tyrihans South, an oil field with a gas cap, and Tyrihans North. The latter is a gas and condensate discovery with a thin oil zone.
Plans call for the Tyrihans structures to be developed with five seabed templates tied back to the Statoil-operated Kristin platform. A 43-kilometer pipeline will carry the wellstream to the Kristin platform.
Like the Kristin gas, the Tyrihans gas will be sent through the Asgard Transport system to the treatment complex at Karsto north of Stavanger.
Liquids production – condensate (light oil) and crude – will be combined with Kristin output after stabilization and piped through an existing pipeline to the Asgard C storage ship for export by shuttle tanker.
Tyrihans is due to come on stream in 2009, when spare capacity will be available in Kristin's topside facilities, and represents one of the biggest development projects on the Norwegian continental shelf (NCS) in coming years.
Total development costs are estimated to be around NOK 14.5 billion (nominal). Recoverable reserves are put at roughly 182 million barrels of oil and condensate, and 34.8 billion cubic meters of rich gas.
Statoil has a 46.8 percent interest in the field, while its partners are Total with 26.51 percent, Hydro with 12 percent, Eni with 7.9 per cent and ExxonMobil with 6.75 percent.
