At the well location\r\nseismic mapping indicated structural closure at Brent Group level and below. The\r\nprimary objectives were to find hydrocarbon accumulations within the Brent\r\nGroup and the overlying clastic wedge of Bathonian-Callovian age. Other\r\nJurassic sandstones were also considered as prospective targets. The well was\r\nplanned to reach ca 3500 m total depth, 75m into the Statfjord Group.\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\u003eWildcat well 30/6-8 was spudded with the\r\nsemi-submersible installation Treasure Seeker on 15 June 1982 and drilled to TD\r\nat 3600 m in the Early Jurassic Statfjord Formation. A 17 1/2" pilot hole\r\nwas drilled from 232 m to 950 m. No shallow gas was reported. No serious\r\nproblems occurred while drilling. The well was drilled with seawater and hi-vis\r\npills down to 232 m, with seawater/hi-vis pills and Drispac from 232 m to 955\r\nm, and with KCl/polymer mud from 955 m to TD. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eNo hydrocarbon bearing sandstone\r\nintervals were encountered in this well.

The well penetrated an Intra Heather Formation Sandstone\r\ninterval (2445.5 - 2523.5 m) with 10.6 m net with average porosity of 15.7 %. A\r\nCallovian wedge (2712.5 - 3024 m) was encountered by the well, but no clastic\r\nsediments with reservoir properties were found within the wedge. A total of 147\r\nm of Brent Group (3024 - 3171 m) sediments were encountered. Net sand was 45.9 m\r\nwith an average porosity of 16.1 %. Net sand within the Cook Formation (3349.5 -\r\n3404.",
