It is located in between\r\nlater discoveries such as SmØrbukk, Heidrun, and Midgard. The main targets of\r\nthe well were sandstones of middle to Late Jurassic age. Secondary targets were\r\nsandstones of Early Tertiary, Early Jurassic and Triassic age. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Reference Well for the Ror\r\nFormation.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 6507/10-1 was spudded with\r\nthe semi-submersible installation Sedco 707 on 10 July 1982 and drilled to TD\r\nat 3693 m in the Åre Formation. Tight hole was experienced at the bottom of the\r\n13 3/8" section. While drilling the 12 1/4" section the drill string\r\nstuck. After several attempts to free the string, the well was sidetracked. The\r\nsidetrack was drilled to 2007 m where the string again got stuck. The well was\r\nthen sidetracked again to 2220 m at which point the string got stuck again.\r\nThis time the string was jarred free and the 12 1/4" hole was finally drilled\r\nto 2780 m. Problems with the BOP and wellhead delayed operations in the 8\r\n1/2" section. The well was drilled with spud mud down to 440 m, with a sea\r\nwater/clay built native mud from 440 m to 913 m, and with CMC/gypsum mud from\r\n1971 m to 2149 m. From 2149 m to 2780 m the mud was gradually broken over to a\r\nlignosulphonate (Spersene) mud, and from 2780 m to TD a Spersene/XP 20 mud was\r\nused.\u003c/p\u003e\r\n\r\n\u003cp\u003eSandstones were found in the Middle and\r\nEarly Jurassic. The Early Tertiary sandstones were not present. The Triassic\r\nsandstone horizon was not penetrated. An 11% methane gas peak was recorded from\r\na Miocene sandstone at 590 m but no fluorescence was noted. Sandstone in the\r\ninterval 1790-1805 m produced a slow crush cut fluorescence as did the Late\r\nJurassic mudstone between 2779 m and 2828 m in the Spekk Formation. These were\r\nthe only hydrocarbon indications recorded in the well. Logs and RFT pressure\r\ngradients proved all potential rese",
