The well was drilled on the Norwegian part of\r\nthe Shetland Basin in the northern North Sea. The objectives were to test the\r\nhydrocarbon potential in the Middle Jurassic Brent Group (primary objective),\r\nand the Early Jurassic Cook Formation and Statfjord Group (secondary objectives).\r\n\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eAppraisal well 30/7-8 was re-entered with\r\nthe semi-submersible installation Treasure Seeker on 23 November 1980. It was\r\nkicked off at 3755 m and drilled to final TD at 4813 m in the Late Triassic\r\nHegre Group. No significant problem was encountered in the operations. The well\r\nwas drilled with Spersene/XP-20/Resinex/Drispac water based mud from kick-off to\r\nTD. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe primary target reservoir, Tarbert\r\nFormation came in at 4058 m.
