HOUSTON, Feb. 16 -- Norway's Storting (parliament) on Feb. 16 approved Statoil ASA's plan for development and operation of Tyrihans oil and gas field in the Norwegian Sea.
Development includes Tyrihans South, an oil field with a gas cap, and Tyrihans North, a gas and condensate discovery with a thin oil zone. Reserves are put at 182 million bbl of oil and condensate, and 34.8 billion cu m of rich gas.
Statoil plans to install five seabed templates to be tied back, via two 45-km pipelines, to the Kristin platform, which it also operates. The development involves four subsea production and gas injection structures and a template for seawater injection (OGJ Online, Feb. 3, 2006).
Tyrihans is due on stream in July 2009 when spare capacity will be available in Kristin's topside facilities.
Tyrihans gas will be sent through the Åsgard Transport System to the treatment complex at Kårstø, north of Stavanger, while condensate and crude production will be combined with Kristin output and piped through an existing pipeline to the Åsgard C storage vessel for export by shuttle tanker.
The Tyrihans partners will spend 14.5 billion kroner developing Tyrihans, said to be one of the biggest projects on the Norwegian continental shelf in coming years. Statoil holds a 46.8% interest in the field; partners are Total SA 26.51%, Norsk Hydro ASA 12%, Eni Norge AS 7.9%, and ExxonMobil Corp. 6.75%.
