The primary objective for 35/11-5 was the\r\nMiddle Jurassic Brent Group. Reservoirs were expected in the Tarbert, Ness,\r\nEtive, and Oseberg Formations. Secondary there was a possibility for reservoir\r\ndevelopment in the Late Jurassic Sognefjord Formation. Similar sands are the\r\nmain reservoir in the Troll area, and were expected to be well developed in the\r\neastern part of the block. No shallow gas warnings were given. Boulders might\r\nbe encountered in the interval 395 - 532 m. The well was planned to be drilled\r\nto a total depth of 3678 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 35/11-5 was spudded with the\r\nsemi-submersible installation Sovereign Explorer on 27 June 1991 and drilled to\r\nTD at 3769 m in the Early Jurassic Statfjord Formation. The well reached a\r\ndepth of 1118 m before technical problems caused the well to be plugged back\r\nand sidetracked. Further problems in the sidetrack caused the well to be\r\nabandoned and re-spudded on 18 July 1991, 50 m northwest of the original\r\nlocation. The first well bore was drilled with seawater and hi-vis pills. The\r\nsecond and final well bore was drilled with seawater and hi-vis pills to 1010\r\nm, and with KCl/polymer mud from 1010 m to TD \u003c/p\u003e\r\n\r\n\u003cp\u003eWater bearing sandstones were drilled in\r\nPalaeocene. The Draupne Formation was penetrated at 2657.5 m. The Sognefjord\r\nFormation came in at 2875 m and consisted predominantly of claystones with some\r\nsandstone interbeds. Shows were observed in cuttings, and RFT samples recovered\r\ncontained oil and gas. However, reservoir quality of the sandstones was\r\ngenerally poor and there was less than 5 m of net pay. In the Middle Jurassic\r\nBrent Group, shows were observed in cores from 3208 m down to 3305 m. Light\r\noil/condensate and gas was recovered from an RFT sample taken at 3214 m.\r\nReservoir quality was however poor with only 5.",
