Tullow Oil Norge's Lupus well, in production licence (PL) 507, in the Norwegian North Sea, is to be plugged and abandoned after failing to find hydrocarbons.
The well (31/10-1), which was 35km southeast of the Oseberg Sør Field and 110km west of the island of Sotra, was the first well in production licence PL 507.
The primary objective of the Lupus-1 wildcat exploration well was to find hydrocarbons in the Paleocene Hermod Formation in a stratigraphic trap. The well also targeted reservoir quality sandstones of the Paleocene Ty Formation of the Rogaland Group.
The well found good quality sandstones in the Paleocene Hermod Formation but no hydrocarbons were encountered. No sandstones were found in the Paleocene Ty Formation.
Tullow said: "The well will now be plugged and abandoned and well data gained will be used to calibrate geological and geophysical uncertainties and reduce risks in future exploration wells."
The well was drilled to a total depth of 2357 metres by the semisubmersible Borgland Dolphin drilling rig in 121m water depth.
Tullow Oil Norge is the operator with 60% equity (40% paying interest). The other partners are Explora Petroleum (20%), Ithaca Energy (10%) and North Energy (10%).
