The main objectives were to test the\r\nMiddle Jurassic Brent Group as well as sands in the Early Jurassic Dunlin Group\r\nand Statfjord Formation on a structure located in the south western corner of\r\nthe block. No reservoirs were anticipated above the Late Kimmeridge\r\nUnconformity. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 35/8-2 was spudded with the\r\nsemi-submersible installation Sedco 704 on 30 August 1981 and drilled to TD at\r\n4336 m in the Early Jurassic Statfjord Formation Formation. During hole opening\r\nof the 36" section, the drill string parted and left the bit, opener and\r\ndrill collars in the hole. Fishing was unsuccessful. The well was re-spudded 11\r\nSeptember 1981 and the 17 1/2" pilot hole was drilled without problems.\r\nWhen opening to 36" washing and reaming was required. Few problems were\r\nencountered in the 26" section. While drilling the 17 1/2" hole one\r\nexperienced problems with tight hole at 830 to 883 m, 1610 -1720 m and 1915 -\r\n1940 m. Repairs of the BOP and other unrelated rig problems occurred for 13\r\ndays during the drilling of this section. Tight hole was also experienced in\r\nthe upper part of the 12 1/4" section and at 3100 m where pore pressure\r\nalso started increasing. Some problems were experienced when coring in the 8\r\n1/2" section. When running in hole with a new bit, the pipe became stuck\r\nat 3662 m. Twenty-one days were spent fishing before the hole was plugged back\r\ninto the 9 5/8" casing. The well was then sidetracked from 3482 m and the\r\n8 1/2" hole was drilled down to 3954 m. Some minor problems with tight\r\nhole and differential sticking occurred. A 6 1/8" hole was then drilled to\r\nTD at 4336 m. The well was drilled with seawater / pre-hydrated bentonite / gel\r\ndown to 2155 m and with seawater/bentonite/polymer/LF-5 mud from 2155 m to 3538\r\nm. From 3538 to TD the well was drilled with KCl/polymer mud, which w",
