    JUNKED: The drilling operation has been terminated due to technical problems.
    P&A: Exploration: The well is plugged and abandoned, and can not be reentered for further use. Development wells: The production/injection from/to the well is stopped and the well is plugged. The wellhead is removed or else made unavailable for further well operations.
    PLUGGED: The wellbore has been plugged, but the upper parts of the wellbore can be re-used. A sidetrack might be drilled at a later stage.

  • Wellbore history
    General
    The main objective of well 6608/10-5 was to prove oil accumulation in Middle and Lower Jurassic Sandstones of the Fangst and Båt Groups.
    Operations and results
    Wildcat well 6608/10-5 was spudded with the semi-submersible installation "Ross Isle" on 5 July 1995 and drilled to a total depth of 3200 m, in the Åre formation. The well was drilled with seawater and bentonite/CMC EHV to 1215 m and KCl/Anco 2000 mud with 3-5 % glycol (Anco 208) from 1215 m to TD. No hydrocarbons were found. No cores were cut. No wire line fluid samples were taken. The well was plugged and abandoned as a dry well on 6 August 1995.
    Testing
    No drill stem test was performed
