The objective\r\nwas to test the Late Jurassic and Early Permian sections in a rotated fault\r\nblock on a terrace NW of the Tor Field. The block is situated in the Central\r\nTrough, which is part of the failed Mesozoic North Sea, rift system. The\r\nCentral Trough comprises a complex series of narrow discontinuous highs and\r\nlows with a NW-SE trend. The most important basins are the Feda Graben, the Breiflab Basin and the Søgne Basin. From the Feda Graben/Breiflab Basin up to the Sørvestlandet\r\nHigh several rotated fault blocks form platforms and small highs, named the Cod\r\nTerrace, the Hitra High and the Steinbit Terrace. The NW Tor Prospect is\r\nsituated on a Terrace between the Hitra High and the Feda Graben.\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 was spudded with the 3-leg\r\njack up installation on 29 February 1992 and drilled to TD at 5258 m in the\r\nEarly Permian Rotliegendes Group. Drilling went without problems to 2081m were\r\nthe well was sidetracked because the string became stuck while taking a survey.\r\nWhile pulling out of the hole, following the cutting core to a depth of 4357.1\r\nm, an influx of gas occurred and the well was shut in. Following a 22 hours\r\nwell kill operation, the well was brought back under control. A second\r\ntechnical sidetrack was taken at 4724 m due to a twist-off of the bottom hole\r\nassembly. The well was drilled with seawater/gel down to 466 m, with KCl mud\r\nfrom 466 m to 2146 m, with Soltex from 2146 m to 2582 m, with Soltex/Drispac\r\nfrom 2582 m to 4151 m, with HTHP mud from 4151 m to 4724 m, and with High Temp\r\nmud from 4724 m to TD\u003c/p\u003e\r\n\r\n\u003cp\u003eTo thin hydrocarbon-bearing intervals\r\nwere present in the Hod Formation. At 4340 m a major hydrocarbon bearing sand\r\nof the Late Jurassic Ula Formation was encountered.
