The\r\ngeological objective of the well, in this early stage of exploration, was to\r\ntest all horizons down to the Permian Rotliegendes Group. The well also had as\r\na technical objective to test the use of a large, single hull vessel for\r\ndrilling in the North Sea.\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 2/8-1 was spudded with the vessel\r\n&quot;Drillship&quot; on 28 November 1967. This was the first drilling\r\noperation in Norwegian waters in which a vessel was used. Many problems arose\r\nduring the drilling of 2/8-1. Repeated failures of the anchor mooring chains at\r\ntensions loads of only 10?50 % of their rated breaking occurred. To this, the\r\nweather conditions in the North Sea turned out to be more severe than had been\r\npredicted. Several storms in the 25 to 30 year category were encountered, and\r\nin January a storm that would be expected once every 75?100 years occurred with\r\nmaximum waves of 15 - 17 m. After this storm the Drillship was in shipyard for\r\nrepairs and modifications from 19 January to 8 March 1968. Even so, these\r\nfailures of anchor chains eventually resulted in failure of the BOP stack and\r\n13 3/8&quot; well head after having drilled to 2595 m, and made clear that\r\ndrilling could not continue safely. \u003c/p\u003e\r\n\r\n\u003cp\u003eBesides the mooring problems, other\r\ndifficulties occurred. While testing in the 12 1/4&quot; hole, the Drill Stem\r\nTest (DST) - tool dropped into the hole. The hole was reamed and the fish\r\nretrieved. The drill pipe stuck twice when making trips, first at 2118 m. The\r\npipe was not recovered and a fish was left from 2007 - 2118 m. A cement plug\r\nwas set and the hole side tracked. The pipe stuck again at 2237 m and a new\r\nfish was left from 2052 to 2237 m. Two cement plugs were set, one in the 13\r\n3/8&quot; casing shoe and one in the casing from 140 m to sea floor.
