OSLO -- The PL 416se partnership for block 31/8 in the Norwegian North Sea will drill a well targeting the Breiflabb prospect.
According to partner Rocksource, the sanctioned well should be drilled in May 2011 by the semisub Borgland Dolphin. Rocksource has swapped its rig slot in 2011 with operator E.ON Ruhrgas' slot in 2012 in order to secure the earlier drill date.
The primary target in the prospect could contain mean recoverable resources of 170 MMboe, with the chances of success estimated at 44%. Risk and volumetric estimates have been high-graded based upon evaluation of integrated electro-magnetic data.
Block 31/8 is in the Stord basin, around 30 km (18.6 mi) southwest of the Troll field. Rocksource describes Breiflabb as a fault-controlled, structural trap with potential for multiple vertically-stacked reservoir intervals.
The main reservoir potential lies in shallow-marine sandstones of the Upper Jurassic Sognefjord Formation. There may be deeper reservoir potential in the underlying Lower – Middle Jurassic Brent and Dunlin groups. The main prospect risk is associated with source and migration.
