Summary
The drilling activity on the Norwegian Shelf has reached a level of more than 40 wells per year. Exploration licensing has taken place in seven rounds. The success rate on the Norwegian Shelf are very high both in the North Sea and area to the north.
In the North Sea three exploration models are established, the Chalk play, the Lower Tertiary deep sand play and Jurassic and older pre unconformity sand. Common for all the plays are Jurassic source rocks. In the north the established play types are related to pre unconformity Jurassic-Upper Jurassic sand.
