The well\r\nlocation is near the top of a large anticline whose axis trends northwest with\r\na 200 km2 closure at the pre-Zechstein horizon. The structure was considered as\r\na north-western extension of the Fynn Falster High. The expected reservoirs\r\nwere Danian and Maastrichtian chalky limestone, Jurassic sandstone, Rotliegend\r\nsandstone, and Carboniferous or Devonian sandstone. It was supposed that all or\r\nnone of these reservoirs could be encountered. Basement could be found at\r\ndifferent depths, owing to the difficulties in identifying main seismic\r\nhorizons below the top of the chalky limestone.\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 3/7-1 was spudded with the jack-up\r\ninstallation Ocean Tide on 1 August 1973 and drilled to TD at 3227 m, 9 m into\r\nbasement rock. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe Paleocene and Maastrichtian horizons\r\nwere encountered at 2690 m and 2852 m respectively, which was 41m and 28 m low\r\nto the geologic prognosis estimated depths. The basement (chloritic gneiss) was\r\nencountered directly underlying Turonian limestone.\u003c/p\u003e\r\n\r\n\u003cp\u003eOnly the middle part of the chalky Maastrichtian\r\nsection had some reservoir characteristics with inferred porosity from the BHC\r\nlog about 12% from 2852 m to 2951 m and about l8% from 2951 to 2984.5 m. The Maastrichtian\r\nreservoir was water wet based on the IES log. The underlying Turonian -\r\nCampanian limestone was very tight. No hydrocarbon shows were reported from the\r\nwell other than traces of dry gas. \u003c/p\u003e\r\n\r\n\u003cp\u003eOne core was cut in basement at TD from\r\n3221 - 3227 m.
