STAVANGER -- BG Norge has failed to find further oil while appraising its Blabaer discovery in the Norwegian North Sea.
Appraisal well 34/5-1 A, drilled by the semisub Bredford Dolphin, was designed to prove petroleum in a structure close to last month’s discovery well, which intersected 65 m (213 ft) gross of oil-bearing strata in Lower Jurassic reservoir rocks (the Cook formation). But the result this time round was a dry hole.
The well did encounter a reservoir in the Cook formation, with reservoir rocks and quality as expected. Data acquisition and sampling have been conducted, and the partners will integrate the results with data from well 34/5-1 S before deciding on further delineation of the discovery.
This is the second exploration well in production license 374 S. The discovery location is around 25 km northeast of Statoil’s Snorre field complex.
The well was drilled in a water depth of 387 m, to a vertical depth of 3,706.5 m (12,160 ft) below the sea surface, and was terminated in the Early Jurassic-age Burton formation. The Bredford Dolphin will next mobilize to North Sea license 337 to drill wildcat well 15/12-22 for Det norske oljeselskap.
