It was considered a possibility that\r\nsuch an interval would be of reservoir quality, though probably being better\r\ndeveloped to the east. The well was also expected to fulfil the license\r\ncommitment by drilling into Devonian rocks, or to 4000 m, whichever came first.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was spudded with W.Wilhelmsen\r\nsemi-submersible rig Treasure Scout on 5 May 1985 and drilled through ?Early\r\nCarboniferous sediments to TD at 3502 m in altered dolerites of indeterminate\r\nage. Due to a work conflict, while drilling a pilot hole prior to the 17\r\n1/2" section, drilling was halted for 13 days. The drill string penetrated\r\na pocket of shallow gas between 618 m and 622 m as predicted by shallow seismic\r\nreflectors. The well was drilled with seawater and hi-vis pills down to 1050 m\r\nand with KCl/polymer mud from 1050 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eA major unconformity (613 m) separates\r\nthe Tertiary from the Triassic sediments with missing sediments in the age\r\nrange Late Triassic to Early Paleocene. The Triassic sandstone prognosed to\r\n1850 m was not found. A second stratigraphic break was observed at 1945 m,\r\nwhere Middle Triassic sediments were found resting unconformably on sediments\r\nof Early Permian age (the Base Ladinian Unconformity). A",
