No clarification of Aldous North

22. September 2011

Det norske has made a small discovery in Aldous Major North. Statoil, operator of license 265 (Johan Sverdrup), is in the process of completing exploration well 16/2-9S.

16/2-9 S is located about 12 kilometers northwest of the major oil discovery Aldous Major South (16/2-8), situated in the mid parts of the North Sea.

The well encountered a thin oil column within an intervall of eight meters in the Draupne Formation. The reservoir rocks are thinner, and have poorer quality, than expected. For the time being, the size of the discovery makes it economically non-viable.

The oil, however, was encountered within the depth intervall of the oil column in Aldous Major South. This supports prior analysis of a regional continuous oil accumulation in blocks 16/2 and 16/3. Licensees in PL 265 are therefore considering further exploration drilling of the Aldous Major North structure in 2012, in order to determine the potential in other parts of the structure.

16/2-9 S is the sixth exploration well in license 265. The well is now being permanently plugged and abandoned. The operation was carried out by Transocean Leader, which is now set for appraisal drilling of Aldous Major South.

Det norske holds 20 percent in license 265. Statoil is the operator with a 40 percent share. Other licensees are Petoro (30 percent) and Lundin (10 percent).
