It was drilled on a salt dome with about 122 m of vertical closure over\r\nan area of about 23 km2. The well was programmed to test all porous formations\r\nfrom the Miocene to the Triassic. The main objectives were the Palaeocene\r\nDanian, Middle Jurassic, and Triassic sections. Secondary possibilities were\r\nseen in the Oligocene - Miocene, Late Cretaceous, and Early Cretaceous. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Reference Well for the Bryne\r\nFormation.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 8/12-1 was spudded with the\r\njack-up installation Maersk Explorer on 31 May 1971 and drilled to TD at 2875m\r\nin the Skagerrak Formation. Some difficulties were encountered with\r\nover-pressured shales from 853 m to 1113 m before setting 13-3/8" casing,\r\ncementing the 13-3/8" casing, and with lost returns immediately below the\r\n9-5/8" casing set at 1903 m. The well was drilled with a\r\nSeawater/gel/IMCO-RD-333 mud system with 3 % to 5 % oil. \u003c/p\u003e\r\n\r\n\u003cp\u003eMethane gas in quantities up to 12% was\r\nrecorded on the mud-gas detector during drilling of the Miocene and Oligocene\r\nclays. No significant reservoir sections were encountered in this section, and\r\nthe gas was most probably released directly from the richly organic clays. Two\r\nvery weak oil shows were obtained in the Middle Jurassic sandstones. In porous\r\nsandstones from core No.3, where one of these shows was observed, up to 9.4%\r\nresidual oil was measured. However, evaluation of the logs showed that all\r\nporous intervals penetrated were water bearing. The formation water in the\r\nMiddle Jurassic sandstones was calculated to have a salinity of 140,000 ppm\r\nNaCl. \u003c/p\u003e\r\n\r\n\u003cp\u003eThree conventional cores were cut in the\r\nintervals 6181 feet - 6237 feet (1884.0 m - 1901.0 m), 8811 feet - 8817 feet\r\n(2685.6 m - 2687.4 m), and 8919 feet - 8969 feet (2718.5 m to 2733.8 m). One\r\nfluid sample was taken on wire line at 2666 m. The tool was opened for 10 min\r\nand recovered 100 cc of salt water (55,",
