The\r\nmain objects of this well was to reveal petrophysical characteristics in an\r\narea where development wells could be located, to appraise the gas column\r\nheight and gas in place, to get static formation pressure in order to estimate\r\ncommunication with the main Frigg field, and to obtain cores from the upper\r\npart of the Frigg Formation and the Balder formation for static and dynamic\r\npetrophysical measurements. Prognosed depth of the Frigg Formation was 1922 m,\r\nand planned TD was 2450 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\u003eAppraisal well\r\n25/2-9 was spudded with Golar Nor Offshore A/S semi-submersibel rig Nortrym on\r\n14 June 1985 and completed 24 July 1985 at a depth of 2297 m in the Paleocene\r\nBalder Formation. At 2297 m 800 l/min of mud was lost due to a leakage between\r\n13 3/4" casing and 20" casing. The 9 5/8" casing was set to 888\r\nm and the well was gradually brought under control. During this operation a\r\npart of the under-reamer was lost into the hole, and fishing went on for two\r\ndays.\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Frigg came in at\r\n1935 m with hydrocarbons from 1935.9 m. Gas/oil contact was encountered at 1960\r\nm, and an oil/water contact at 1972 m with brown oil stain on cuttings down to\r\n2008 m. A total of 12 cores were cut with a total length of 214.25 m with 86%\r\nrecovery. Ten cores were cut from 1939 m to 2145 m in the upper Frigg\r\nFormation, across the hydrocarbon bearing zone and all fluid contacts and two\r\ncores were cut from 2220 m to 2256 m in the tuffaceous Balder Formation. The\r\ncores consisted mainly of sands, more or less consolidated. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was plugged\r\nand abandoned as an oil and gas discovery.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test\r\nwas performed\u003c/p\u003e\r\n",
