Statoil has completed drilling operations on exploration well 6608/10-9 in the Lerke structure approximately 175 km off the coast of Helgeland in production license 128. The well was drilled in water depths of 375 meters and had a total depth of 2400 meters below the sea surface. The well was completed in rocks from the Early Jurassic Age.
The well proved oil sandstone in the Middle Jurassic, which was the secondary target for the drilling activity. The volume and production properties of the oil in this level have not yet been clarified. Further studies will determine whether the discovery is commercial. Only traces of oil were recorded in the main target for the well, which was sandstone from the Early Jurassic Age.
The drilling operation on Lerke was carried out by the semisub, Deepsea Bergen, with a total drilling time of 25 days.
