The Heidrun SW prospect\r\nconsists of a downthrown fault closure, W-segment and an independent up-thrown\r\nthree way dip-closure; the SW-segment. The trap is a structural hanging wall\r\ntrap, and formed as a consequence of Late Jurassic to Middle Cretaceous\r\nextensional tectonics. The prospect has a 3-way dip closure to the north, west\r\nand south and an up-thrown fault closure to the east, requiring a fault seal in\r\norder to have hydrocarbons present. The primary objective was to prove up\r\ncommercial reserves for the Heidrun SW structure, by testing the hydrocarbon\r\npotential of the Middle Jurassic Fangst Group, by means of wire line logging\r\nand coring. Secondary objectives were to test the Early Jurassic Tilje and Åre\r\nreservoirs and the Early Cretaceous sandstones for Hydrocarbon potential. The\r\nflowing potential and productivity of a discovery, if made, should be evaluated\r\nby MDT and DST-tools. If no indications of hydrocarbons in Late Tilje were\r\nfound, the well would reach TD at 3706 m TVD RKB (3710 m MD RKB) or 50 m below\r\ntop Tilje Formation. If hydrocarbons were present, the well would reach TD\r\ndeeper, at 3926 m TVD RKB (3930 mMD RKB) or 270 m below top Tilje.\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 6507/7-11 S was spudded with the\r\nsemi-submersible installation Mærsk Jutlander on 25 June 1997 and drilled to TD\r\nat 3749 m (3744 m TVD RKB) in the Early Jurassic Tilje Formation. The well was\r\ndrilled with Seawater and hi-vis pills down to 754 m and with KCl glycol\r\nenhanced mud from 754 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eNearly 40 m net thickness (of 100 m\r\ngross) of Fangst Group sandstones was encountered. Apart from elevated high\r\nbackground levels of mud gas in the interval 1500 m to 1540 m (7% to 11%) the\r\nwell was practically devoid of hydrocarbon indications and the target reservoir\r\nzones in the Fangst and Båt",
