Idemitsu drills a dry hole in the North Sea

Idemitsu has come up dry after drilling 35/7-1 ST2 wildcat well in production license 377 S, about 7 kilometers west of the Vega field in the Norwegian North Sea. 

The primary exploration target for the well was to prove hydrocarbons in Middle Jurassic reservoir rocks (the Brent group). The secondary exploration target was to prove hydrocarbons in the Cook formation from the Early Jurassic Age. The well encountered both the Brent group and the Cook formation, but both had poorer reservoir quality than expected. Data acquisition and sampling have been carried out, and this has been classified as a dry well. 

The well is the first wildcat well in production license 377 S, which was awarded in APA 2005. 

The Aker Barents rig drilled to a vertical depth of 4773 meters below the sea surface, and was terminated in the Dunlin group from the Early Jurassic Age. The water depth at the site is 386 meters. The well will now be permanently plugged and abandoned.
