A prominent NE-SW\r\ntrending ridge complex occupies the southern part of this block, separating the\r\n Møre Basin from the northern North Sea along the Møre Trøndelag fault complex.\r\nThe reservoir rocks of the Oksen prospect were interpreted as synrift submarine\r\nfan deposits of Kimmeridge age located in a half graben between two Triassic\r\nHighs. Trapping mechanism were stratigraphically dependant on sealing faults\r\ntowards rotated Triassic rocks in southeast. The objectives of the well were to\r\ntest the hydrocarbon and reservoir potential of the Late Jurassic play-concept\r\n(Magnus Sand) and to test the geophysical and structural interpretation of the\r\narea and give valuable information on palaeontology and geochemistry.\u003c/p\u003e\r\n\r\n\u003cp\u003eShallow gas warnings were given for two\r\nlevels.\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 6201/11-02 was spudded with\r\nthe semi-submersible rig Deepsea Bergen on 8 January 1991 and drilled to TD at\r\na total depth of 3778 m in the Jurassic Heather Formation. The well was drilled\r\nwith seawater/CMC/viscous plugs down to 780 m, with KCl/polymer mud from 780 m\r\nto 3335 m, and with gel/lignosulfonate mud from 3335 m to TD. The well was\r\ndrilled without major problems, except for 3 days lost rig-time due to low\r\nleak-off value at the 20" casing shoe.\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Late Jurassic was encountered at 3339\r\nm, which is 24 m lower than prognosed. No potential reservoir rocks were\r\nencountered in the Late/Middle Jurassic. The biostratigraphic breakdown was\r\ndifficult to interpret from approximately 3650 m and to TD with Triassic shale\r\noverlying the Late Jurassic Heather Formation towards TD. It is thus possible\r\nthat the Jurassic and Triassic sequences in this well represent slumped/slided\r\nsediment packages similar to the situation in well 33/5-2 not very far to the\r\nsouth.
