StatoilHydro has begun production from the Tyrihans oil and gas field in the Norwegian Sea. The new field comprises Tyrihans South, an oil field with a gas cap, and Tyrihans North, a gas and condensate discovery with a thin oil zone. The recoverable volumes in the reservoirs are 186 million barrels of oil and condensate, and 41.5 million standard cubic m of gas. Its proximity to other fields on the Halten Bank allows Tyrihans to use existing infrastructure.
