The operator of a production license 442 – Aker BP ASA, has succeeded in the drilling of wildcat well 25/2-21 (Liatårnet).
The effectively was drilled about 40 km northeast of Alvheim field within the central part of the North Sea, and about 200 km northwest of Stavanger.
The primary and the secondary exploration targets for the nicely were to prove petroleum in reservoir rocks from the Early Miocene period (the Skade formation).
Well, 25/2-21 encountered an oil column within the major exploration target of about 28 m in sand layers with outstanding reservoir quality. The oil/water contact was not encountered. The secondary exploration target consisted of a water-bearing sand layer of about 12 m, additionally with extraordinarily good reservoir quality.
Preliminary estimates point out that the size of the discovery is between 13 and 32 MMscm of recoverable oil. The move potential and restoration charge are uncertain and will have to be clarified previous to the preparation of a possible development plan.
The well was not formation-tested, however extensive data acquisition and sampling have been carried out.
That is the ninth exploration nicely in production license 442. The license was awarded in APA 2006.
The nicely was drilled to a vertical depth of 1,170 m beneath the seafloor and was terminated in rocks from the Oligocene age (the Hordaland group). Water depth on the site is 110 m. The well has now been permanently plugged and abandoned.
The well was drilled by the Deepsea Stavanger drilling facility, which can now transfer on to the Norwegian Sea to drill wildcat well 6608/6-1 in production license 762, der Aker BP ASA is the operator.
