09/04/2010 BG Norge AS, operator of production licence 374 S, is in the process of completing the drilling of appraisal well 34/5-1 A on the 34/5-1 S (Blåbær) oil discovery.
The discovery was proven in March 2010 in Lower Jurassic reservoir rocks (the Cook formation), and is situated about 25 kilometres northeast of the Snorre field centre in the North Sea. Well 34/5-1 S proved 65 metres (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 licence 374 S. The licence was awarded in TFO 2005.
The well was drilled to a vertical depth of 3706.5 metres below the sea surface, and was terminated in the Burton formation from the Early Jurassic Age. Water depth at the site is 387 metres. The well will be permanently plugged and abandoned.
The well was drilled by the Bredford Dolphin drilling facility, which will now proceed to production licence 337 in the North Sea to drill wildcat well 15/12-22, where Det norske oljeselskap ASA is the operator.
