Description

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

On the Norwegian Continental Shelf bedrock of pre-Devonian age are regarded as basement in a petroleumgeological context. More than 50 wells in the North Sea, Norwegian Sea and Barents Sea have penetrated pre-Devonian rocks. Most of these wells were drilled on structural highs with depth to top basement quite evenly distributed between 1200 and 4000m.

The thicknesses drilled have generally been in the order of a few meters. 5 wells have drilled more than 100m of basement rock:

2/6-3 (142m),

16/1-4 (146m),

16/1-5 (195m),

35/3-2 (233m),

6306/10-1 (207m).
