The well is situated less\r\nthan 1 km from the UK-Norwegian median line, where the UK Drake Field, an\r\noil/gas field in UK block 2215was discovered close to the median line. Well\r\n6/3-1 was designed to test possible hydrocarbon accumulations at different\r\nlevels. The main target was Jurassic and Triassic sandstones. Secondary targets\r\nwere Paleocene sandstones (Heimdal Formation), and Late Cretaceous\r\nporous/fractured chalk.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was spudded with the\r\nsemi-submersible installation Deepsea Bergen 2 November 1984 and drilled to TD\r\nat 3560 m in the Triassic Skagerrak Formation. Drilling of the well proceeded\r\nwithout significant problems, but five and a half rig days were spent waiting\r\non weather. The well was drilled with gel/seawater to 520 m, with\r\ngypsum/polymer from 520 m to 2926 m, and with lignite/lignosulphonate from 2926\r\nm to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eTarget reservoir sandstones of\r\nJurassic/Triassic age came in at 2965 m with oil and gas/condensate. A\r\nhydrocarbon column of 72 m was proven with oil/water contact at 3037 m. FMT\r\ngradients and oil stain on cores indicated a GOC at 3013 m. Secondary target\r\nsand (Heimdal Formation) was not found. Logs and shows indicated hydrocarbons\r\nin Late Cretaceous chalk/limestone, most strongly from 2900 m to 2925 m, but\r\ntest of this interval was negative. FMT pressure measurements in the larger\r\ninterval from 2804 m to 2918.5 m in the chalk were all unsuccessful and showed\r\na tight formation. Eight cores were cut in the well from 2968 m to 3116.5 m.\r\nSegregated FMT samples were taken at 3021.5 m (0.87 g/cm3-oil and gas), at\r\n3007.5 m (0.780 g/cm3-condensate, gas, and mud filtrate), at 3016 m (oil, mud\r\nfiltrate, and gas), at 2992 m (0.77 g/cm3-condensate, mud filtrate, and gas),\r\nat 2998.5 m (condensate and gas), and at 2966 m (0.77 g/cm3-condensate, mud\r\nfiltrate, and gas). \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permane",
