The objective was to evaluate\r\nthe Mjød structure in the Tor Formation on the eastern flank of the Valhall\r\nField.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 2/8-16 S was drilled in\r\ncombination with development well bores on the Valhall Field, using a down hole\r\nsplitter system (DHS) marketed by Baker Oil Tools and Kværner National. The\r\n2/8-16 S well was spudded from the "Splitter Housing" installed at ca\r\n1409 m and proceeded without too much trouble to 1662 m where mud losses were\r\nseen. At 1927 m the losses had become severe, and this had not been seen on\r\nValhall before. Examination of a seismic dip-map at approximately 1700 m TVD\r\nRKB showed that the well track had crossed a major fault at about the same\r\ndepth as the losses became severe. The seismic image indicated the zone could\r\nbe about 75 m wide. After curing the mud loss problems drilling continued to\r\n3139 m, where a wiper trip was made back to 2100 m. On running back in hole an\r\nobstruction was hit at 2133 m. After working past this obstruction it became\r\nevident that the hole had collapsed. At this time it was decided to abandon the\r\nwell track in favour of drilling an oil production well 2/8-A20 B. Well 2/8-16\r\nS was drilled using an oil-based mud.\u003c/p\u003e\r\n\r\n\u003cp\u003eAs the reservoir section was not reached,\r\nno log evaluation was done and the well was classified as a junk well.\u003c/p\u003e\r\n\r\n\u003cp\u003eNo cores were cut and no wire line fluid\r\nsamples taken.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 14\r\nMarch as a junk well.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n",
