The primary\r\nobjectives of the well were to test the hydrocarbon potential of the Brent\r\nGroup, Cook, and the Statfjord Formations on the J-north compartment with\r\nrespect to commercial volumes and future relinquishment decisions. It was not\r\npossible to locate a vertical well on the J-north compartment which could test\r\nall three reservoir levels in an optimal position. Priority was therefore given\r\nto the Brent reservoir, and the well location was chosen in order to prove\r\nhydrocarbons in the Brent Group, leaving a minimum of untested hydrocarbon\r\npotential in the lower Ness reservoir up dip of the well. Secondary objectives\r\nwere to penetrate the Cook and Statfjord Formations shallower than the water up\r\nto (WUT) top Statfjord in well 30/9-5 (2564 m MSL).\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 30/9-15\r\nwas spudded with the semisubmersible installation \"West Vanguard\" on\r\n7 December 1993 and was drilled to a&\r\ntotal depth of 2764 m in the Early Jurassic Statfjord Formation. The\r\nwell was drilled with sea water and hi-vis pills down to top of 12 1/4\"\r\nsection at 936 m, and with ANCO 2000 mud with glycols from 936 to TD. The Brent\r\nGroup was encountered at 2249 m and was proven to be oil bearing in the lower\r\nNess Formation, with an ODT at 2348.5 m. The ORE (Oseberg/Rannoch/Etive)\r\nFormations contained residual oil. The Cook Formation was proven water bearing\r\nthough moderate to weak shows were recorded from sidewall cores taken over the\r\ninterval 2465.5 - 2475.5 m. The Statfjord Formation was proven water bearing.\r\nThree conventional cores were recovered from the intervals 2240 m to 2250 m\r\n(Hardråde, Åsgard, and Ness Formations), 2256m to 2281 m (Ness, ORE, and Drake\r\nFormations), and 2283 m to 2306 m (Drake Formation). A wire line MDT sample of\r\nacceptable quality was recovered from 2249.9 m in the oil zone in the Ness\r\nFormation. The well was plugged back and permanently aba",
