Endeavour's fourth North Sea well unsuccessful

LOS ANGELES, Dec. 30 -- Endeavour International Corp. has completed the drilling of the fourth well in its 10-well exploration campaign in the North Sea, and it found no hydrocarbons.

The 31/26b-18 well, in the Central Graben in the UK sector of the North Sea, was drilled to 10,540 ft TD to test the Turriff and Tulliallan prospects.

In the primary Turriff objective, the well encountered 450 ft of Jurassic Fulmar sand with good porosity. The upper Fulmar section contained 63 ft of reservoir quality sands with an average porosity of 16%. However the sand was found to be water wet, indicating a failure of the trap to seal, which was the key risk factor for the well.

The Tulliallan objective did not encounter reservoir-quality rock.

Endeavour and its partners have begun to plug and abandon the well. Endeavour was operator with a 60% working interest.
