The primary\r\nobjective of the well was to find hydrocarbon accumulations of significant size\r\nin the Middle Jurassic. Secondary objectives were hydrocarbon accumulations in\r\nthe Early Jurassic sandstone. The well should also verify the geophysical and\r\nstructural interpretation and improve the geological, paleontological and\r\ngeochemical understanding of the area. Total depth was to be in rocks of\r\nTriassic age or 4000 m in order to satisfy the licence commitment.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 6406/3-2 was spudded with the\r\nsemi-submersible installation West Vanguard on 28 June 1986 and drilled to TD\r\nat 4523 m in the Early Jurassic Åre Formation. The well was drilled practically\r\nvertical down to the deepest survey point at 4261 m (4260 m TVD). In the\r\ntesting phase 543.5 hrs were spent on fishing to get the cement stinger loose.\r\nThe well was drilled with spud mud down to 965 m, with gypsum/polymer mud from\r\n965 m to 2301 m, with gypsum lignosulphonate mud from 2301 m to 3930 m, and\r\nwith lignosulphonate mud from 3930 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Middle Jurassic sandstones (Garn\r\nFormation) were penetrated at 3930 m and were found to be HC-bearing. The oil contact,\r\nprobably and oil-down-to contact, was found from geochemical methods at\r\napproximately 4030 m. The logs indicated that the oil/water contact was at 4335\r\nm. Oil shows were recorded in several intervals below this depth throughout\r\ndown to TD. RFT data indicated that both Ile and Ti1je Formations were\r\nimpermeable. \u003c/p\u003e\r\n\r\n\u003cp\u003eA total of 285 m core was recovered in 17\r\ncores from the Garn, Not, Ile, Ror, and Tilje formations. No fluid samples were\r\ntaken on wire line.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 22\r\nNovember 1986 as an oil discovery.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo drill stem tests were performed in\r\nthe well.
