Multilateral and smart wells with downhole control equipment and injection pumps for seawater standing directly on the seabed could yield some 18 million barrels of additional oil from Tyrihans.
This oil and gas project is being pursued by StatoilHydro in the Norwegian Sea, about 35 kilometres east of Kristin and a similar distance south-east of Åsgard.
It will be developed as a satellite to Kristin, with pressure support in the form of gas injection from the Åsgard B platform.

Production is due to begin in the summer of 2009.
Tyrihans is the largest StatoilHydro-operated field off Norway which remains to be developed.
It holds 176 million barrels of oil and 30 billion cubic metres of gas.
While Tyrihans South is an oil reservoir with a gas cap, Tyrihans North is a gas reservoir with a thin underlying oil zone.
These two formations are connected via a water-filled saddle. Reservoir properties are normal.
