The main objective of the well was\r\nto test the hydrocarbon potential in the Early to Middle Jurassic Fangst Group.\r\nSecondary objectives were to test the reservoir properties the underlying Tilje\r\nFormation, as well as possible sand development in the Tertiary. The well\r\nshould also evaluate the source rock properties in the Early Jurassic Åre\r\nFormation. Planned total depth was 4526 m RKB TVD beneath a seismic marker\r\ninterpreted as Triassic Evaporite. The well was the first well on a new block\r\nand the pressure prognosis was uncertain. Formation pressures were to be\r\nwatched closely while drilling.\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 6406/11-1 S was spudded with\r\nthe semi-submersible installation Treasure Saga on 19 October 1990 and drilled\r\nto TD at 4185 m in the Late Triassic Red Beds. To avoid shallow gas the well\r\nwas spudded and drilled deviated from a location 260 m NNW of the planned\r\ntarget location. During drilling the Nordland Group, two shallow gas intervals\r\nwere penetrated at 893 - 897.5 m and 1148 - 1150 m. To get back to vertical\r\ndrilling the well was deviated from 1235 m to 2165 m MD. Only minor problems\r\noccurred while drilling down to the 12 1/4" section. After drilling the 12\r\n1/4" hole down to 3395 m, the VSP tool become stuck at 3383 m. A total of\r\n5 days were spent recovering the wire line and miring the fish down. Only minor\r\nproblems with tight spots occurred while drilling to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eFormation pressure was hydrostatic down\r\nto ca 1520 m, from where a gradual pressure build up was indicated in the\r\nHordaland Group down through the Rogaland Group, estimated to a maximum of 1.60\r\ng/cc EMW at 2400 m in the upper part of the Shetland Group. From here a slight\r\npressure depletion down to approximately 3000 m was indicated. From 3000 m down\r\nto the Jurassic ",
