STAVANGER -- Wildcat well 25/10-9 in the North Sea is dry, according to Lundin Norway. The primary exploration target for the well was to prove petroleum in reservoir rocks from the Early Eocene age (lower Frigg or upper Balder formation). The secondary exploration target was to prove petroleum in reservoir sandstones in the Oligocene (the Grid formation), Upper Cretaceous (lower Shetland group), and in the Upper Jurassic.
The primary target encountered rocks with very poor reservoir quality, the company reports. The secondary target encountered sandstones of moderate thickness and good reservoir properties, but these did not contain hydrocarbons.
The semisub Songa Dee drilled the well to a vertical depth of 2,959 m (9,708 ft) below the sea surface. The well was terminated in Middle to Upper Jurassic sandstones and will now be permanently plugged and abandoned.
