25/8-16 S and 25/8-16 A

22/05/2009 Press Release 28/2009: ExxonMobil Exploration & Production Norway AS (ExxonMobil), operator of production licence 027 D, has concluded the drilling of wildcat well 25/8-16 S and appraisal well 25/8-16 A. Det norske oljeselskap ASA (Det norske) carried out the drilling operations on behalf of ExxonMobil. The wells are located approximately 6 kilometres southeast of the Jotun field in the North Sea.

The primary exploration target for the well was to prove petroleum in Paleocene reservoir rocks. The secondary exploration target was to prove petroleum in  reservoir rocks from the Lower Jurassic. Limited quantities of oil were proven in a relatively thin reservoir in the Paleocene (the Heimdal Formation). The secondary target in the Statfjord Formation was water-bearing. None of the wells were formation-tested, but data collection and sampling were conducted.

These are the two first exploration wells in production licence 027 D after it was carved out from production licence 027 B in December 2007. 25/8-16 S was drilled to a vertical depth of 2107 meters below sea level and was concluded in the Statfjord formation in Lower Jurassic rocks. 25/8-16 A was drilled to a vertical depth of 2164 metres and was concluded in the Shetland Group. The sea depth is 126 meters. The wells will now be permanently plugged and abandoned.

The wells were drilled by Bredford Dolphin, which now will proceed to production licence 383 in the Norwegian Sea to drill wildcat well 6507/3-6 where Det norske oljeselskap ASA is the  operator.
