The well took 48 days to\r\ncomplete and was drilled with unical/lignosulphonate/caustic based mud.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eReservoir quality rock was absent\r\nthroughout the well. The first signs of oil were seen in Palaeocene tight siltstones\r\nwith poor porosities. These were described as bright gold yellow fluorescence\r\nwith a bright white streaming cut. Gas levels in the Shetland Group were low\r\nand no shows were seen in this group. A DST was run over part of this section\r\nbut yielded only drilling mud. From 3267.3 m, within the Early Cretaceous, gas\r\nlevels rose significantly and were associated with fair to poor shows in the\r\nMarls. The fluorescence was described as gold in colour with a slow pale yellow\r\ncut. From 3444 m, gas and shows increased and were contained in slightly\r\nargillaceous, hard limestone. Oil staining was seen and the fluorescence\r\ndescribed as dark yellow gold with a pale yellow to very light brown cut. Mandal\r\nFormation shale was the first Jurassic age rocks seen. Gas levels were very\r\nhigh through these shales and the shows were described as bituminous with no\r\ndirect fluorescence and a pale yellow cut. Between 3578 - 3600 m a gross\r\nsandstone unit was indicated by the gamma ray log. In rough",
