Lundin Norway AS, operator of Production License 304, has concluded the drilling of wildcat well 25/10-9. The well was drilled about 20 km southwest of the Balder and Grane fields in the North Sea.
The primary exploration target for the well was to prove petroleum in reservoir rocks from the Early Eocene age (lower Frigg or upper Balder formation). The secondary exploration target was to prove petroleum in reservoir sandstones in the Oligocene (the Grid formation), Upper Cretaceous (lower Shetland group), and in the Upper Jurassic.
The well was dry. The primary target encountered rocks with very poor reservoir quality. The secondary target encountered sandstones of moderate thickness and good reservoir properties, but these did not contain hydrocarbons.
25/10-9 is the first exploration well in Production License 304, which was awarded in APA 2003.
The well was drilled to a vertical depth of 2959 m below the sea surface, and was terminated in Middle to Upper Jurassic sandstones.
25/10-9 was drilled using the semisubmersible drilling rig Songa Dee, which will now proceed to production license 338, about 30 km further south in the North Sea, to drill appraisal well 16/1-12 on the 16/1-8 "Luno" oil discovery, operated by Lundin Norway AS.
