The primary objective was to ascertain that the\r\nHeidrun field extension into the 6507/8 block and to verify reserve\r\ncalculations. Secondary objectives were to verify geological model and\r\nstructural interpretation, and define oil water contact in the Tilje Formation.\r\nIt was also intended to provide more information on reservoir characteristics\r\nand hydrocarbon fluids, and maximum input of data for reservoir simulation\r\nstudies. The Fangst Group was expected at 2245 m, and the Tilje Formation at\r\n2340 m. Prognosed TD was 2590 m.\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 6507/8-1 was spudded with\r\nthe semi-submersible installation Dyvi Delta on and drilled to TD at 2600 m in\r\nEarly Jurassic sediments of the Åre Formation. Drilling proceeded without\r\nsignificant problems. The well was drilled with seawater and hi-vis pills down\r\nto 1063 m, with KCl/polymer mud from 1063 m to 2235 m, and with\r\ngel/polymer/lingo mud from 2235 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe only oil shows reported above the target\r\nreservoir were on sandstone in a cuttings sample at 2235, and on limestone in a\r\nSWC at 2238 m, both samples from the Melke Formation. The Middle Jurassic\r\nFangst Group was penetrated at 2248 m and the Early Jurassic Tilje Formation at\r\n2386.5 m. These reservoir sandstones were found to be hydrocarbon bearing with\r\na gas/oil contact at 2312 m and an oil/water contact at 2480 m. \u003c/p\u003e\r\n\r\n\u003cp\u003eA total of 9 cores were cut from 2249 m\r\nto 2469 m in the Garn, Not, Ile, Ror, and Tilje Formations. Core no 1 from the\r\nGarn Formation was loose sand and was lost on the drill floor while recovering\r\nfrom core barrel. One relatively good RFT fluid sample was taken at 2317 m. It\r\ncontained oil with a density of 0.88 g/cc (29 deg API).\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 9 December 1986 as a gas and oil appraisal.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo DST tests were performed in the Tilje\r\nFormation.\u003c/p\u003e\r\n\r\n\u003cp\u003eDST",
