The primary\r\nobjective of exploration well 6406/8-1 was to test the hydrocarbon potential in\r\nthe Middle Jurassic Fangst group and the Lower Jurassic Båt group (Ror and\r\nTilje formations). Possible intra-Cretaceous sands related to a seismic marker\r\nwere considered as second target. Well 6406/8-1 was the first well drilled on\r\nthe licence. It is located on a domal structure at the Base Cretaceous\r\nUnconformity. The prognosed TD for the well was 5027 m.\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 6406/8-1 was spudded with the\r\nsemi-submersible installation SSDV Vinni on 15 September 1987 and drilled to\r\nfinal TD at 4914 m in the Early Jurassic Åre Formation. The well was drilled\r\nwater based.\u003c/p\u003e\r\n\r\n\u003cp\u003eIt was drilled initially to a total depth\r\nof 4942 m where it had penetrated the Fangst Group. The well kicked and the\r\ndrill string was lost in the hole. Due to incomplete fishing operation a\r\nsidetracked well was drilled. The sidetrack was spudded on 22 January 1988 at\r\n4262 m. The Fangst Group was once again penetrated and an intermediate logging\r\nwas performed. Drilling commenced to 4914 m. Due to hazardous drilling with\r\ngains and stuck pipe it was agreed that 4914 m was to become the TD of this\r\nwell. A final logging operation was made comprising FMT and RFT. The Fangst\r\nGroup down to top Ile Formation was interpreted from data available from the\r\nfirst hole. Due to failed MWD and no wire line logs below 4500 m in the first\r\nhole the Båt Group is interpreted from the sidetrack. Horner corrected wire\r\nline log BHTs at TD gave a formation temperature of 172 deg C. \u003c/p\u003e\r\n\r\n\u003cp\u003eSome gas dissolved in water was tested in\r\nthe Ile Formation; otherwise no moveable hydrocarbons were seen in the well.\r\nDull yellow spots and weak pale green cut fluorescence was described on\r\nsandstone from 3145 to 3190 m.
