The Beta\r\nsegment is a part of the Midgard horst. This horst is defined by NNV trending\r\nnormal faults. It is separated from the other compartments by a ENE trending\r\ncross fault and exhibits true vertical closure at Base Cretaceous level. The\r\nprimary target was reservoir rocks of the Middle Jurassic Fangst Group with the\r\nobjective to establish the GWC within a good sand and to perform a DST in a\r\nformation not previously being tested (the Ile Formation). The location was\r\nchosen relatively high on the structure in case the hydrocarbon contact for\r\nBeta was different from what was seen in the Alpha and Gamma structures. The\r\nwell should reach Triassic rocks or drill to 500 m below the coal reflector.\r\nThe proposed depth was 3250 m. The pre-drill classification of the well was\r\nwildcat.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Type Well for the Ile and Not\r\nFormation of the Fangst Group.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 6507/11-3 was spudded with the\r\nsemi-submersible installation Treasure Saga on 3 June 1985 and drilled to TD at\r\n3250 m in the Triassic Grey Beds. While drilling the reservoir, mud weight had\r\nto be raised gradually to 1.6 g/cm3 due to high trip gas. Approximately 2 weeks\r\nwere lost due to a work conflict. The well was drilled with spud mud down to\r\n421 m, with gel mud from 421 m to 868 m, with gypsum/polymer mud from 868 m to\r\n2615 m, and with gel mud from 2615 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe average background gas down to the 20"\r\ncasing point was 0.4% to 0.8% with peaks at 505 m (3.43%), 540 m (1.08%), 576 m\r\n(1.76%) and 663 m (1.97%). Methane was the only gas component present. The well\r\nproved mainly claystones down to the Fangst Group. The Cainozoic with a total\r\nthickness of 1771 m overlies a 271 m Cretaceous sequence.
