Noil Energy ASA, operator of production license 001 B, has concluded drilling wildcat well 16/1-9. The well is located about 20 kilometers northeast of the 15/3-1 S Gudrun discovery in the North Sea.
The primary exploration target for the well was to prove petroleum in the Middle Jurassic and Upper Triassic (in a prospect called Draupne). The well proved light oil with a small gas cap in Middle Jurassic reservoir rocks. It is too early to indicate the size of the discovery as the well did not confirm the oil/water contact. The secondary exploration target was to prove petroleum in the Paleocene, which was dry.
The well was not formation-tested, but data was collected in the form of core and fluid samples. The discovery will now be mapped in detail prior to planning a potential appraisal well to determine the size of the discovery, as well as to obtain additional reservoir data.
This well is the third exploration well in production license 001 B, which was originally awarded in the first licensing round in 1965 and subsequently partitioned in 1999.
The well was drilled to a vertical depth of 2511 meters below the sea surface, and was concluded in the Skagerrak formation in the Upper Triassic.
Water depth at the site was 111 meters. The well will now be permanently plugged and abandoned.
Well 16/1-9 was drilled by the Bredford Dolphin which will now proceed to production license 373 S in the northern North Sea to drill wildcat well 34/3-1 S operated by BG Norge.
