BG Norge AS, operator of production license 374 S, is in the process of completing the drilling of appraisal well 34/5-1 A on the 34/5-1 S Blabaer oil discovery

The Blabaer discovery was proven in March 2010 in Lower Jurassic reservoir rocks (the Cook formation), and is situated about 25 kilometers northeast of the Snorre field center in the North Sea. Well 34/5-1 S proved 65 meters (gross) of oil-bearing strata. 

The objective of well 34/5-1 A was to prove petroleum in a structure adjacent to the 34/5-1 S discovery. The well is dry. A reservoir was encountered in the Cook formation with reservoir rocks and quality as expected. Data acquisition and sampling have been carried out. The results of the well will be integrated with data from the discovery well 34/5-1 S, before a final decision is made as regards future delineation of the discovery. 

This is the second exploration well in production license 374 S. The license was awarded in TFO 2005.
In waters measuring 387 meters deep, the Blabaer discovery well was drilled to a vertical depth of 3706.5 meters below the sea surface, and was terminated in the Burton formation from the Early Jurassic Age. The well will be permanently plugged and abandoned. 

The well was drilled by the Bredford Dolphin, which will now proceed to production license 337 in the North Sea to drill wildcat well 15/12-22, where Det norske oljeselskap ASA is the operator.
