The\r\nmain objective was to test the hydrocarbon potential of the Tertiary and the\r\nMesozoic sediments. Specific objectives were Paleocene sandstone, the Late\r\nCretaceous carbonate section, and the Jurassic. Sandstones in the Early\r\nCretaceous and Triassic were seen as possible secondary targets.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWildcat well 7/11-1 was spudded with the\r\nsemi-submersible installation Ocean Viking on 26 February 1986 and drilled to\r\nTD at 3974 m in Late Permian Zechstein Salt. The only significant drilling problem\r\nencountered was sloughing of shale between ca 1675 m and 2315 m. Deviation was\r\nnegligible above 3500 m, from where it increased from 4.5 deg to 11.5 deg at\r\napproximately 3960 m. The true vertical depth therefore probably is 4-5 m short\r\nof measured depth at TD. A Drispac-Flosal-Desco mud system was used to a depth\r\nof 3290 m. At this depth the system was converted to a sodium chloride saturated\r\nDrispac-Flosal-Desco system. The salt saturated system was used to total depth.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well proved gas and condensate in three\r\ntests in a 5 m thick intra-Balder Formation sand (DST 5) and the Forties\r\nFormation from top at 2904 m down to 2989 m (DST 3 and 4). Below this depth DST\r\n1 and 2 produced only minor amounts of hydrocarbons due to tight formation.
