Seawater was used to drill the 36" hole and\r\nreturns were to the sea floor. A sea water/ Spersene/XP-20 mud was used to a\r\ndepth of 2735 m, approximately to the top of the rock salt. The mud system was\r\nthen converted to an invert emulsion oil based mud, which was used to TD. While\r\ndrilling at 4699 m (TD) a salt water flow occurred and contaminated the mud.\r\nThe flow was controlled, but the condition of the hole was bad and the lower\r\napproximately 120 m of the well, therefore, has not been logged. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well penetrated relatively complete\r\nTertiary, Cretaceous, Late Jurassic, and the Permian sequences. The Triassic\r\nand the Early Jurassic were missing. The Permian Zechstein salt was 1437 m\r\nthick, resting on a thin Kupferschiefer sequence. None of the sedimentary\r\nsequences penetrated contained significant amounts of hydrocarbons. Three conventional\r\ncores were cut in the interval from 4380.6 m to 4575.4 m from the Zechstein\r\nsalt and into the Rotliegendes Group. No fluid samples were taken. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned 10\r\nJune 1969 as a dry well.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n\r\n\r\n\r\n\r\n",
