The\r\nUtsira High is a large, flat, fault bounded basement feature. The objective of\r\nthis early well in the North Sea was: "To test the hydrocarbon potential\r\nof the sedimentary section; investigate the lithology and sequence in this\r\nportion of the North Sea basin; and to partially fulfil Esso's drilling\r\nobligation to the Norwegian Government incurred on behalf of the Licences."\r\n\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 16/2-1 was spudded with the\r\nsemi-submersible installation Ocean Traveler on 11 July 1967 and drilled to TD\r\nat 1906 m, 33 m into basement rock. There were no noteworthy drilling problems\r\nencountered while drilling. Initial drilling from the sea floor to 381 m was\r\nwith seawater and gel without casing. Returns were to the sea floor. Below 381\r\nm to total depth of 1906 m, a seawater slurry with gel, CMC, Spersene, XP-20,\r\nCaustic Soda, Barite, and 0-10% diesel oil was used.\u003c/p\u003e\r\n\r\n\u003cp\u003eOil shows were seen on cores in tight\r\nCretaceous carbonate rocks in the Tor Formation. The shows were strong and\r\ncontinuous from top Tor Formation down to 1776 m, and then became patchy. These\r\nrocks were too impermeable to justify further tests in this well. Weak shows\r\nwere seen also in a thin Oligocene sand from 1256 m to 1263 m and in Eocene\r\nmudstones from 1631 m to 1637 m, Balder Formation. Dead oil/tar was observed in\r\nfractures in the basement rock. \u003c/p\u003e\r\n\r\n\u003cp\u003eFive cores were cut from 1739.5 m to\r\n1821.8 m in the Tor Formation chalk and two more cores were cut from 1879.1 m\r\nto 1883.7 m in the basement. Four Formation Interval Tests (FIT) were performed\r\nat 1748.9 m, 1733.4 m, 1642.6 m, and at 1738.2 m. The tests, one in Early\r\nTertiary shales and three in Late Cretaceous carbonates, did not show any\r\nhydrocarbons.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 9\r\nAugust 1967 as a well with shows.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo dr",
