It was drilled on a crestal\r\nposition of an elongated faulted anticline approximately 11 km long and 5 km\r\nwide. The primary objective horizon was the Jurassic Sandstone section, which\r\nfrom seismic information was expected to have closure of 39 km2 with a maximum\r\nof 66 m of vertical closure. Late Cretaceous limestone, Paleocene sandstone and\r\nTriassic Sandstone were secondary objectives.\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 8/11-1 was spudded with the\r\nsemi-submersible installation Ocean Viking on 24 April 1975 and drilled to TD\r\nat 3810 m in the Triassic Red beds. The well was drilled with seawater and\r\nAttapulgite clay down to 458 m, with seawater/Drispac and 3% diesel oil from\r\n458 m to 1219 m, and with seawater/Drispac/lime/4-5% diesel oil from 1219 m to\r\nTD. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe formation tops and thicknesses agreed\r\nwell with the geological prognosis with Paleocene coming in at 1968 m, top\r\nCretaceous at 2143 m, the Jurassic at 2807 m, and top Triassic in the interval\r\n2855 m to 2900 m. In the Paleocene, no sands were developed and in the Upper\r\nCretaceous the limestone was tight. The Jurassic section consisted of 27.4 m of\r\ndark grey shale of Portlandian - Late Kimmeridgian age. The total sand section\r\nhad been eroded away by the Kimmeridgian unconformity. After drilling 975 m of\r\nbarren Triassic section the well was terminated at the prognosed depth of 3810\r\nm without the Zechstein salt having been encountered. The well had no shows and\r\nthus no testing was carried out. No conventional core was cut and no fluid\r\nsample taken. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 29\r\nJune 1975 as a dry well.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n",
