  • Wellbore history

    General
    Well 36/1-3 was drilled to test the Presto prospect east-southeast of the Agat Field on the Måløy slope in the North Sea. The primary objective was to test the hydrocarbon potential in the Early Cretaceous upper and lower Agat Formation sandstones.
    Operations and results
    Wildcat well 36/1-3 was spudded with the semi-submersible installation Transocean Spitsbergen on 1 March 2019 and drilled to TD at 2913 m in basement rock. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 550 m, with KCl/polymer/GEM mud from 550 m to 1109 m and XP-07 oil-based mud from 1109 m to TD.
    The well penetrated sediments of Nordland, Rogaland, Shetland and Cromer Knoll Groups. The entire succession of the Hordaland Group is eroded in the well location. The Early Cretaceous Åsgard Formation rest directly on basement.
    Top Agat Formation was encountered at 2564 m and was 202 m thick, of which 55 metres is reservoir rocks with good to very good reservoir quality. The well is dry without shows. Sixteen pressure measurement were performed within Agat sandstones with wireline tool and confirmed a water gradient with normal hydrostatic pressure.
    No cores were cut. No fluid sample was taken.
    The well was permanently abandoned on 25 March 2019 as a dry well.
    Testing
    No drill stem test was performed.
