StatoilHydro Strikes Oil at Nona Prospect in Norwegian Sea

An oil and gas discovery has been made by StatoilHydro in the Nona prospect, ten kilometers south east of the Asgard field in the Norwegian Sea.

Based on preliminary calculations the size of the find is between 13-31 million barrels of oil and 1-2 billion standard cubic meters of gas.

"The Nona discovery further confirms the good results achieved by infrastructure-led exploration on the Halten Bank," said Sivert Jorgenvag, StatoilHydro's head of infrastructure-led exploration on the Halten Bank.

In his view it is still possible to make new finds in the area.

"Thorough mapping and evaluation of the area have been the key success factors and also form the basis for further exploration activities," said Jorgenvag.

The well was not formation tested, but extensive data gathering and sampling have been carried out.

A development of the discovery involving production via the existing infrastructure will be considered.

The Nona discovery

  • Well 6407/2-5S was drilled to a vertical depth of 3,289 meters below sea level.
  • The well was completed in early Jurassic rocks.
  • The Ocean Vanguard rig drilled the well at a water depth of 250 meters.
  • The well will be permanently plugged and abandoned.
  • Ocean Vanguard will be moved to production license 442 in the North Sea to drill another exploration well.
