The\r\nprimary purpose of the well was to test the Brent Group reservoir on the C-Plus\r\nprospect. A secondary objective was to test the reservoir of the Statfjord\r\nFormation. The well was drilled on a high position of the structure and was\r\nestimated to reach the reservoir at 2349 m MSL. Shallow gas could occur at 448,\r\n500, and 557 m.\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 34/7-16 was spudded with the\r\nsemi-submersible installation Scarabeo 5 on 13 August 1990 and drilled to TD at 2700 m in the Early Jurassic Amundsen formation. At this depth the well\r\nwas temporary abandoned due to time schedule for the rig. No significant\r\nproblems were encountered in the operations. The resistivity log indicated\r\nsmall amounts of gas in a sand layer at 447 m. Otherwise no indication of\r\nshallow gas was observed. The well was drilled with spud mud down to 922 m and\r\nwith KCl mud from 922 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eApart from the sandy Utsira Formation of\r\nMiocene/Pliocene age encountered between 976 - 1081 m the well penetrated\r\nmainly clay stone down to the Top Jurassic. Late Cretaceous (Coniacian age)\r\nsediments were found to rest unconformable on the Middle Jurassic Brent Group reservoir\r\nat 2390 m. The reservoir was hydrocarbon bearing. From the log, pressure\r\ngradient analyses, and FMT sampling the OWC was found at 2487 m, in the Rannoch\r\nFormation. Shows were recorded from 2 m above and to 2 m below the oil-bearing\r\nreservoir. Weak shows were also observed in the upper part of the Cook\r\nFormation.\u003c/p\u003e\r\n\r\n\u003cp\u003eEight cores were cut in the well. One\r\ncore was cut in the Shetland Group, from 1935 to 1953 m, for borehole stability\r\nstudies. Seven cores were cut in the Brent Group and into the Dunlin Group (8.0\r\nm), in the interval 2389 - 2522 m (driller's depth). The Brent core recovery\r\nwas 130.8 m, i.e. 98%. \u003c/p\u003e\r\n\r\n\u003cp\u003eFour FMT segregated samples were taken in\r\nthe Brent Group re",
