The objectives of well\r\n6506/11-3 were: to prove oil in the Lysing, Lange (Cretaceous) and the Rogn\r\n(Jurassic) Formation; to test the hydrocarbon potential of the Nise Formation\r\nand the Åre Formation; and to penetrate the Upper Triassic and test the\r\nreservoir potential in order to prepare for relinquishment.\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 6506/11-3 was spudded with the\r\nsemi-submersible installation Ross Rig on 8 July 1992 and drilled to TD at 4350\r\nm in the Middle Jurassic Not Formation. The well was drilled with seawater and\r\nhi-vis pills down to 1020 m, with Gypsum/PAC-Polymer mud from 1020 m to 2020 m,\r\nwith Gypsum/PAC/Thermopol/Ancotemp mud from 2020 m to 3717 m, and with\r\nAncotherm mud from 3717 m to TD. Due to high pressure the well was terminated\r\nat a shallower depth than prognosis\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Nise Formation was encountered at\r\n2357 m and proved to be 196 m thick. It was predominantly Clay/Claystone with\r\nsome thin sandstone layers, mostly in the upper part. The Lysing Formation was\r\ntested and produced water with minor amounts of gas. Only 2 m Spekk Formation\r\nwas encountered and the Rogn Formation was not developed. Sandstones of the\r\nJurassic Garn Formation were water bearing. Shows were recorded in the Lysing\r\nand Garn Formation. \u003c/p\u003e\r\n\r\n\u003cp\u003ePost-well geochemical screening of cores\r\nshowed shales of good potential in the interval 3920 m to 3990 m across the\r\nCenomanian ? Turonian in the Lange Formation. This may possibly be seen as an\r\nequivalent to the Blodøks Formation in the North Sea. \u003c/p\u003e\r\n\r\n\u003cp\u003eTen cores were cut in the well. Core 1\r\nwas cut from 3143.5 m to 3170.5 m in the Lysing Formation. Cores 2, 3, and 4\r\nwere cut in the interval 3919 m to 3945.6 m in Upper Cenomanian ? Turonian\r\nsediments of the Lange Formation. Cores 5, 6, and 7 were cut in the interval\r\n3976 m to 4003 m in Albian to Cenomanian sediments of the Lange Formation.\r\nCores 8, 9, ",
