The primary objective\r\nof the well was to test the potential of Valanginian and Hauterivian\r\nstratigraphic prospect 7122/2, 3-A. Additional objectives were to undertake a\r\ncoring and sampling programme necessary for evaluation of the hydrocarbon\r\npotential of the 7122/2 3-A prospect and the surrounding area; to obtain an\r\nimproved understanding of the reservoir potential, source rock development and\r\nmaturity of the area; and to obtain better stratigraphic and velocity control.\r\nPlanned TD was at least 50 m into the Middle Jurassic Stø Formation, and if\r\nhydrocarbons were encountered, to drill on until shows ceased.\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 7122/2-1 was spudded with\r\nthe semi-submersible rig Polar Pioneer on 7 October 1992 and drilled to TD at\r\n2120 m in the Middle Jurassic Stø Formation. The drill string stuck at 669 m in\r\nthe 24" section and a technical sidetrack was performed. Apart from this\r\ndrilling operations went on without significant problems. The well was drilled\r\nwith seawater and hi-vis pills down to 734 m and with KCl/PHPA/polymer mud from\r\n734 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe primary target, The Knurr Formation,\r\nwas encountered from 1831.5m to 1954.5m and was water bearing. It consisted of\r\nmassive sandstone sequence. Average horizontal permeability from cores was\r\n636.3 mD. The secondary target, the Stø Formation, was also water bearing.
