The main objective was to\r\ntest the W-1 prospect located on the western margin of the Trøndelag Platform,\r\non the eastern edge of the Ellingråsa Graben. The structure was seen as a domed\r\nN-S striking horst restricted by the main platform fault to the west and a\r\nrelated antithetic fault to the east with throws of approximately 350 m and 100\r\nm, respectively. Primary target was the Middle Jurassic sandstones of the\r\nFangst Group. A secondary target was the Lower Jurassic sandstones of the Tilje\r\nFormation, and to penetrate the coal horizon in the Åre Formation. Proposed TD\r\nwas at 2700 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 6507/12-3 was spudded with Wi1h.

The well was drilled with spud\r\nmud down to 380 m, with gel mud from 380 m to 920 m, with Gypsum / Polymer mud\r\nfrom 920 m to 1949 m, and with a gel mud again from 1949 m to TD. A gas flow\r\noccurred between the 20" and 30" casing. The casing was perforated at\r\n705 m and cement successfully squeezed. Gas flow continued to be a problem and\r\nthe 13 3/8" casing was also perforated and cement squeeze was performed in\r\nboth the lower and upper perforations.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Quaternary/Tertiary Sequence was 1596\r\nm thick and consisted predominantly of marine claystones. Cretaceous was\r\nrepresented by a 75 m sequence of Springar Formation. Two metre of Spekk\r\nFormation was encountered at 1937 m, followed by 33 m of Melke Formation. The\r\nFangst Group was penetrated at 1974 m, 20 m above the prognosed depth. MWD\r\ndisplayed fall in resistivity and the formation was considered dry. All\r\nJurassic sandstone sequences were water bearing. A number of gas peaks were\r\nrecorded from 474 m to 804 m, but there were no oil shows observed in the well.\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo cores were attempted in the in",
