The initial well 16/6-2 was drilled to 3131 m in the Shetland Group with\r\nthe drill vessel Glomar Grand Isle. The well found good shows in Paleocene\r\nsandstones and was suspended in October 1971. The primary objective of the re-entry\r\nwas to deepen the well and test the Dogger (Middle Jurassic) deltaic sands. A\r\nsecondary objective was to test the Lias section (Early Jurassic).\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 15/6-2 re-entered on 9 May\r\n1974. It was drilled with the semi-submersible installation Drillmaster to TD\r\nat 4779 m in the Late Permian Zechstein Group. The pipe stuck temporarily three\r\ntimes in intervals below 4602 m. Due to hole problems and tight spots no logs\r\nwere run below 4611 m The well was drilled with a seawater /lignosulphonate mud\r\nfrom re-entry point to TD. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe only hydrocarbon reservoir penetrated\r\nwas the Dogger gas-condensate sands from 3582 to 3641 m. The lower part of\r\nDogger section and all of the Lias section were cut out of this test by an\r\nerosional unconformity and/or faulting. The missing interval has good potential\r\nfor additional reservoir quality sands. In addition, the Late Triassic has good\r\nsand development that could be adequate for reservoiring hydrocarbons. During\r\nthe drilling of the Triassic and Permian section (3688 to TD), the background\r\ngas in mud and cuttings was near zero, which probably is related to lack of\r\nsource material for hydrocarbons.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eNo shows were recorded except in Dogger.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eFive cores were cut with 100% recovery in\r\nthe interval 3582.3 to 3641.1 m.
