OSLO, Norway – Idemitsu Petroleum has drilled a dry hole with its first well in a Norwegian North Sea license.
Well 35/7-1 ST2 was drilled by the semisub Aker Barents on the Apollon prospect in PL 377 S, 7 km (4.3 mi) west of the Vega field.
According to the Norwegian Petroleum Directorate, the chief target for the well was in Mid-Jurassic reservoir rocks (the Brent group). The secondary target was in the Early-Jurassic Cook formation.
Although the well encountered both formations, reservoir quality in each case was poorer than expected.
The well was drilled in 386 m (1,266 ft) water depth, and to a vertical depth of 4,773 m (15,659 ft) below the sea surface. It will be permanently plugged and abandoned.
Aker Barents now heads to production license 482 in the Norwegian Sea.
