Tyrihans is a complete subsea solution tied back to existing installations and infrastructure on the Kristin and Åsgard fields in the Halten Bank area of the Norwegian Sea.
The field comprises Tyrihans Sør, an oil field with a gas cap, and Tyrihans Nord, 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 metres of gas.
Its proximity to the other fields on the Halten Bank means that Tyrihans can use the existing infrastructure.
The wellstream from Tyrihans is sent through a 43-kilometre pipeline to Kristin for processing. The gas is sent ashore through the Åsgard Transport line while oil and condensate are piped to the Åsgard C storage ship for onward transport by tanker. Kristin and Tyrihans share the same operations organisation.
Tyrihans was the largest field we brought on stream in 2009. Newly developed well technology secures a high recovery factor for the field's resources.
