ExxonMobil Exploration & Production Norway AS, operator of production license 028 S, is in the process of completing the drilling of wildcat well 25/10-10, located just to the west of the Balder field in the North Sea. Det norske oljeselskap ASA carried out the drilling activity on behalf of ExxonMobil.
The objective of the well was to prove petroleum in Lower Triassic reservoir rocks (the Skagerrak formation). The well encountered the Skagerrak formation, with good reservoir quality as expected. However, the reservoir rock contained water.
The well is the first exploration license in production license 028 S. Production license 028 S was carved out of the original PL 028, which was awarded on May 23, 1969 in the 2nd licensing round.
The well was drilled to a vertical depth of 2473 meters below the sea surface and was terminated in the Zechstein group in the Upper Permian.
Water depth at the site is 123 meters. The well will now be permanently plugged and abandoned.
Well 25/10-10 was drilled by the Aker Barents semisub, which will now proceed to production license 460 in the North Sea to continue the drilling of wildcat well 25/1-11, where Det norske is the operator.
