STAVANGER, Norway -- Statoil Petroleum has proven further oil in the Gudrun field area in the Norwegian North Sea.
Well 15/3-9 was drilled by theTransocean Leader in 108 m (354 ft) of water in production license 187, 3 km (1.8 mi) east of Gudrun. The objective was to prove petroleum in Upper to Middle Jurassic reservoir rocks (the Draupne and Hugin formations).
According to the Norwegian Petroleum Directorate (NPD), oil was discovered in an 18-m (59-ft) column in the Draupne formation in a good-quality reservoir. The well also encountered a 35-m (115-ft) gas and oil column in the Hugin formation in reservoir rocks of varying reservoir quality.
Data acquisition and sampling are complete, as are two small-scale formation tests of oil-bearing zones, with flow properties as expected.
NPD’s preliminary estimate suggests a find in the range 0.5-3 MMcmoe recoverable.
The licensees will consider a tie-in to the new facilities emerging through the Gudrun field development.
This was the second exploration well in the license, awarded in 1993 under Norway’s 14th licensing round. It was drilled to a vertical depth of 4,630 m (15,190 ft) subsurface and terminated in the Mid-Jurassic Sleipner formation.
Transocean Leader will next drill a shallow well to investigate the seabed conditions at Gudrun where the new platform will be installed.
