Enterprise Oil announces successful appraisal well in Norway

Enterprise Oil has completed the drilling of the Skarv
appraisal well, about 200 kilometres off the coast of 
Helgeland in north Norway.

Well 6507/5-2 was drilled down dip from the discovery
well in a water depth of 347 metres to a vertical depth
of 3,877 metres below sea level, and terminated in rock
of early Jurassic age. The Smedvig West Alpha rig was
used to drill the well.

The well discovered gas pay in the Jurassic and has
successfully confirmed the extent of the hydrocarbons in
this area of the Skarv structure. The well was not tested
as sufficient data was collected through coring and an
open-hole logging programme.

The co-venturers are analysing the well results to define
further the field's potential.

John Crowle, General Manager, Enterprise Oil Norway
commented: 'This successful appraisal well has
contributed significantly to our understanding of the
Skarv area, and confirms that there is significant
potential in the whole Skarv-Idun-Norne trend. Further
drilling is scheduled in the area, and studies of
potential development models continue.'
