The well was designed to appraise the hydrocarbon potential and define\r\nthe hydrocarbon-water contacts. Primary target was Middle and Early Jurassic\r\nsandstone. The Fangst Group siltstone member was expected to be sealing at this\r\ndepth. The well would also test if intervals within the Ror and Tilje\r\nformations also could be sealing rocks. Secondary target was the Late\r\nCretaceous Lysing Formation of the Cromer Knoll Group. \u003c/p\u003e\r\n\r\n\u003cp\u003ePrognosed TD was in the Åre formation at\r\n4559 m RKB.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eAppraisal well 6506/12-5 was spudded with\r\nthe semi-submersible installation Dyvi Delta on 17 October 1985 and drilled to TD at 4587 m in the Early Jurassic Åre Formation. The well was drilled with\r\nless than 2.5 deg deviation down to 4235 m. There were minor incidents with a\r\nfailed anchor and lost circulation in the top hole. A poorly cemented 9\r\n5/8" casing required 116 hours amendment before normal drilling could\r\ncommence. The well was drilled with spud mud down to 393 m. From here a pilot\r\nhole was drilled to 1080 m using gypsum/polymer mud, and then opened up using\r\nspud mud. Further drilling was with gypsum/polymer mud from 1080 m to 3519 m,\r\nand with gel/lignite/lignosulphonate from 3519 m to TD. Shallow gas was not\r\nencountered.\u003c/p\u003e\r\n\r\n\u003cp\u003eSecondary target Lysing Formation came in\r\nat 3157 m and primary target Garn Formation at 3948 m. Hydrocarbons were\r\nencountered in both. An OWC was found in the Lysing Formation at 3178.2 m, and\r\nanother OWC in the Garn Formation at 4010.5 m. The Not Formation as well as top\r\nof the Garn Formation was found to be sealing in this well.\u003c/p\u003e\r\n\r\n\u003cp\u003eCores were cut in the Upper Cromer Knoll\r\nLysing Sands and throughout most of the interval from the lower part of the\r\nViking Group at 3910 m down to 4362 m in the Tilje Formation. A total of 429.43\r\nm was recovered in 27 cores. Core n",
