The Lulita prospect extends in to Danish\r\nwaters, and forms part of an elongated, N-S trending, salt induced feature on\r\nthe western margin of the Søgne Basin. The present structural features were\r\ndeveloped during mid Cretaceous time, and closure at Late Cretaceous and\r\nTertiary levels essentially reflects compaction and drape over the Jurassic\r\nhigh. The Jurassic Lulita closure is separated from the area tested by the\r\n3/7-3 well by a faulted saddle, which also is well expressed at Tertiary and\r\nCretaceous levels, providing a vertical closure of some 75 metres. The well had\r\nas primary objective to test the hydrocarbon potential of Middle Jurassic\r\nsandstones within a structural/stratigraphic trap, and as secondary objective\r\nto testing the potential in possible Late Jurassic and Early Cretaceous\r\nsandstones, within a structural trap. Additional objectives included testing of\r\nLate Cretaceous Chalk, found hydrocarbon bearing in the nearby Harald field,\r\nPaleocene/Eocene turbiditic sandstones, and the reservoir quality of the\r\nTriassic sequence. The well should drill some 150 m into rocks of Triassic age.\r\nShallow gas could be encountered at 317 to 388 m, at 485, and at 515 m according\r\nto seismic anomalies.\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 3/7-4 was spudded with the\r\nsemi-submersible installation Hunter on 20 September 1989 and drilled to TD at\r\n3723 m in the Permian Zechstein Group.
