StatoilHydro has started production from the Tyrihans oil and gas field in the Norwegian Sea, the company announced.
Tyrihans is a complete subsea solution tied back to existing installations and infrastructure on the Kristin and Asgard fields in the Halten Bank area of the Norwegian Sea.
The field comprises Tyrihans South, an oil field with a gas cap, and Tyrihans North, a gas and condensate discovery.
Its proximity to the other fields on the Halten Bank means that Tyrihans can use the existing infrastructure, the company said.
"Tyrihans is of strategic importance to StatoilHydro's development of operations in the Norwegian Sea," said senior vice-president for the operations north cluster in exploration and production Norway, Ivar Aasheim.
The licencees at the field are StatoilHydro, which as operator holds a 58.84% stake, Total E&P Norge, which has a 23% stake, Exxon Mobil Corporation with 11.75% and Eni Norge with a 6% stake.
Tyrihans is expected to continue producing until the end of 2029.
