The principal\r\nobjective of this well was to test the hydrocarbon potential of sandstones\r\nwithin the Jurassic section beneath the Late Cimmerian Unconformity.\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 35/8-1 was spudded with the\r\nsemi-submersible installation Sedco-704 on 27 July 1980 and drilled to TD at 4345\r\nm in Late Triassic sediments of the Statfjord Formation. The well was drilled without\r\nsignificant technical problems, but two well kicks occurred .After penetrating\r\nthe Jurassic sand reservoir at 3516m a sudden rapid gas increase was noted, but\r\ndue to mechanical problems could not be measured. This increase was associated with\r\na quantity of reservoir fluids entering the borehole. During controlling of the\r\nkick, a large proportion of gas was vented and light low gravity yellowish oil\r\nrecovered from the mud. A second kick with formation fluids entering the well\r\nbore was taken after coring core no 3 at 3549.6 to 3567.1 m. The well was\r\ndrilled with seawater and viscous slugs down to 890 m, with\r\ngypsum/Lignosulphonate mud from 890 m to 2196 m, and with KCl/polymer mud from\r\n2196 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe top sections down to Top Rogaland\r\nGroup, Balder Formation at 1683 m contained a number of sands and sandy\r\nintervals. From top Rogaland and throughout the Cretaceous section down to top\r\nDraupne Formation at 3186 m the lithology was mainly claystone and limestone.\r\nThe heather Formation came in at 3200 m with two thin Intra-Heather Formation\r\nsandstones at 3219 and 3250 m. Heather Formation shale continued down to the\r\nBrent Group at 3516 m. Frequent sandstones were penetrated in the Brent and\r\nDunlin Groups, and in the Statfjord Formation. \u003c/span\u003e\u003c/p",
