Several discoveries had been made in the\r\nvicinity of Cod, in the Upper Jurassic Ula Formation. The Triassic and Permian\r\nconstituted secondary targets. The well was drilled from the Cod platform with\r\nplanned bottom hole location ca 0.9 km to the east. \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 7/11-7 S was spudded from\r\nthe fixed installation Cod on 29 December 1982 and drilled deviated to TD at\r\n4927 m (4661 m TVD) m in the Late Permian Zechstein Group. The well was\r\nscheduled as a 150-day project but a full drilling crew was still present on\r\nday 349 and it took until day 364 to set a plug above the last set of\r\nperforations. The length of this project was due to problems in drilling and\r\nextended testing to adequately evaluate the three zones of interest. There were\r\ndelays in setting plugs, running casing, fishing, and installing necessary 10,000\r\npsi surface equipment. The testing delays included problems with setting\r\nDHSV's, parted tubing, aborted stimulations, bad weather, and bailing\r\noperations. The well was drilled with seawater/lignite and Desco, an organic\r\nthinner. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well reached all three targets. Late\r\nJurassic Ula Formation sandstone was encountered at 4527 m. The Ula Formation\r\nrested unconformable on Triassic Skagerrak Formation sandstone at 4566 m. The\r\nPermian Zechstein dolomites were encountered at 4856 m. Good shows were\r\nrecorded in the Ula Formation, with weaker shows extending down to 4609 m in\r\nthe Triassic Skagerrak Formation. A second Triassic zone with weak shows was\r\nobserved at 4785 m to 4810 m. Source rock formations were found in the Tertiary\r\ninterval from 1820 m to 2500 m, and in the Late Jurassic shales of the Mandal\r\nand Farsund Formations at 4405 m to 4527. The Tertiary interval had TOC in the\r\nrange 2 - 4 %, Hydrogen Index from 100 to 120 mg HC/g rock, and was ",
