The\r\nwell is located in the eastern part of the East Shetland Basin in the North\r\nSea. The well location is due west of the Oseberg Field and ca 3.5 km from the\r\nUK Border. The primary objective was to investigate structural closure at\r\nEocene and Paleocene with possible sand development.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWell was spudded with the semi-submersible\r\ninstallation on 6 August 1975. While drilling the 36" hole at 167 m, the\r\ndrill string stuck. After several unsuccessful attempts to free the pipe, a\r\nstring shot was run and the hole was plugged. The well was re-spudded on 9\r\nAugust 9 after having moved the rig 200 ft (61 m) south-southeast. From 28\r\nAugust up to 10 September operations were more or less suspended at a depth\r\nbetween 991 and 1001 m due to technical problems with the BOP. The well was\r\ndrilled with gel/seawater mud down to 485 m, with seawater/gel and Drispac from\r\n485 m to 1001 m, and with seawater/gel/Drispac and Lignosulfonate (Unical) from\r\n1001 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eTwo minor shows were reported from Late\r\nEocene. The first, at 1226 m, is a sandstone with patchy yellow to whitish fair\r\nto weak fluorescence with a medium to slow cut. There was no visible oil stain\r\non the sample. The second, in a thin sandstone stringer, at 1525 m, gave a dull\r\ngold fluorescence with a slow streaming cut. At approximately 1700 a thin\r\nsandstone gave a gold fluorescence and a white, milky, streaming cut. The\r\nsamples had a slight oil stain. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well penetrated the Frigg Formation\r\nfrom 1748 to 1909m.
