  • Wellbore history
    General
    Well 6507/8-9 was drilled to test the Carmen prospect on the northern part of the Grinda Graben in the Norwegian Sea, adjacent to the Heidrun Nord Discovery . The primary objective for the well was to prove hydrocarbons in the middle to Early Jurassic (Fangst or Båt Group).
    Operations and results
    Wildcat well 6507/8-9 was spudded with the semi-submersible installation Deepsea Bergen on 2 August 2017 and drilled to TD at 2375 m in the Early Jurassic Åre Formation. Operations proceeded without significant problems. The well was drilled with Seawater down to 1410 m and with Enviromul oil-based mud from 1410 m to TD.
    Top Åre Formation was encountered at 2120.5 m, directly underlying Late Cretaceous sediments belonging to the Kvitnos Formation. No Middle-Late Jurassic and Early Cretaceous sediments were present in the well. The Åre Formation held a gas column of 87 m down to the gas-water contact at 2207 m, of which 35m was sandstone of good reservoir quality with a Net to Gross of 60%. The secondary target in Lower Åre Formation was water wet. The only shows described in the well were in the gas-bearing reservoir.
    One core was cut from 3299 to 3381 m in the Åre Formation with 99% recovery. MDT fluid samples were taken at 2127 m (gas), 2186 m (gas), and at 2240.2 m (water).
    The well was permanently abandoned on 22 August 2017 as a gas discovery.
    Testing
    No drill stem test was performed.
