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

“The Nona discovery further confirms the good results achieved by infrastructure-led exploration on the Halten Bank,” says Sivert Jørgenvåg, 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,” says Jørgenvåg.

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 metres below sea level.
  • The well was completed in early Jurassic rocks.
  • The Ocean Vanguard rig drilled the well at a water depth of 250 metres.
  • The well will be permanently plugged and abandoned.
  • Ocean Vanguard will be moved to production licence 442 in the North Sea to drill another exploration well.
