The Norwegian oil company Det norske has discovered oil in Storklakken close to the Frøy field. The proven volumes are between 7 and 12 million barrels of oil equivalents. Det norske owns 100% of the licence.
Det norske, operator of production licence 460, has completed drilling an exploration well (25/1-11) and a subsequent sidetrack (25/1-11 A) in the Storklakken prospect. The wells were drilled using the Aker Barents drilling rig.
The volumes proved through the two wells are estimated at between 7 and 12 million barrels (1.1 and 1.9 million Sm3).
The wells were primarily intended to prove hydrocarbons in the Frigg/Odin formations (the Hordaland and Rogaland groups). Their secondary purpose was to prove hydrocarbons in the Hermod/Heimdal formations (the Rogaland Group).
Storklakken is located approximately 12 kilometres from the abandoned Frigg field, five kilometres south of discovery 25/1-9, and 220 kilometres northwest of Stavanger.
The wells are the first exploration wells in production licence 460. The licence was awarded as part of APA 2007.
Wells 25/1-11 and 25/1-11 A were drilled to a vertical depth of 2,298 and 2,225 metres below sea level, respectively, until they encountered Palaeocene-age rock in the Heimdal formation.
The ocean depth is 107 metres. The wells will now be permanently plugged and abandoned. The discovery is probably commercial, and tie-in with one of the existing or planned installations in the area is being considered.
