The hole was drilled without\r\nmuch problem down to TD in the 8 1/2" section at 3886 m where logs were run\r\nand a 7" liner was set with shoe at 3885 m. A 5 7/8" hole was drilled\r\nto 4178 (TD) where the well kicked and the pipe got stuck. During killing\r\noperations returns were lost and circulation could not be re-established. The\r\nkick was most likely caused by a salt water flow from a Late Jurassic sand\r\nlense. When trying to back off the drill pipe twisted off, leaving a 340 m fish\r\nin the hole. A cement retainer was set and the well was plugged back to 3789 m.\r\nHence, no logs were run below 3886 m.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eOil shows (dull gold fluorescence with\r\nslow straw-yellow cut) were observed in the shales at the base of the Middle\r\nPalaeocene and at the top of the Danian limestone (3124 - 3178 m), especially\r\nat 3161 m where there was a good straw-yellow streaming cut (faster than the\r\nupper intervals) accompanied by a minor gas peak. In the lower part of the\r\nMaastrichtian limestone gas peaks with 10% C2+ components appeared.
