The main objective of the well 6507/6-2 was to test the hydrocarbon\r\npotential in the Fangst Group and in the Tilje Formation. A secondary target\r\nwas to test the reservoir properties and hydrocarbon potential of a Cretaceous dome\r\nshaped structure interpreted to be a potential Lysing Formation Equivalent. The\r\nsource rock properties in the Spekk and Åre Formations would be tested by the\r\nwell. The commitment was to drill at least 50 m into rocks of Triassic age;\r\nwith planned TD at 4200 m. No shallow gas warnings were given for this well.\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 6507/6-2 was spudded with\r\nthe semi-submersible installation West Alpha on 27 April 1991and drilled to TD\r\nat 4345 m (4343 m TVD RKB) in Late Triassic sediments of the Åre Formation. Only\r\nminor problems occurred while drilling. The well was drilled with spud mud down\r\nto 1040 m, with KCl mud from 1040 m to 3413 m, and with Hi-Temp polymer mud\r\nfrom 3413 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well mainly penetrated claystones\r\nwith minor silt and sandstone intervals down to Top Cromer Knoll Group at 2663\r\nm. In the Cromer Knoll Group the lithology was mainly claystone with thin\r\nintervals of sandstone and limestone. The reservoir in the Fangst Group was\r\nreached at 3727 m, 336 m deeper than prognosed and proved to be dry. However,\r\noil was found in a thin sand bed in the Lange Formation (Turonian age) at 2754\r\n- 2757 m. This sand was neither cored nor production tested, but oil was\r\nrecovered by RFT sampling. \u003c/p\u003e\r\n\r\n\u003cp\u003eSporadic shows were recorded in thin\r\nsandstone stringers at several levels in the Lange Formation (2745 to 2753 m, 2885\r\nm, 2945 - 2955 m, and 2946 m). The well encountered a 102 m thick Spekk\r\nFormation sequence at 3174 m. The Spekk Formation had excellent ",
