It was drilled on the same structure as well\r\n6407/6-2, which was junked due to a disastrous shallow gas blow-out. The\r\nprimary objective was to test for hydrocarbon accumulation in sandstones of Middle\r\nJurassic age (Fangst Group). Secondary objectives were possible hydrocarbon\r\naccumulations in Early Jurassic sandstone, and to verify the geophysical and\r\nstructural interpretation and improve the geological, paleontological and\r\ngeochemical understanding of the area. Total depth was to be in rocks of\r\nTriassic age or 4000 m in order to satisfy the licence commitment.\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 6407/6-3 was spudded with\r\nthe semi-submersible installation Dyvi Delta on 13 December 1986 and drilled to\r\nTD at 3220 m in Late Triassic sediments of the Åre Formation. No significant\r\ntechnical problems were encountered in the operations, which were completed\r\nwithin planned time and budget. No shallow gas was encountered in the well. At\r\n512 m, the interval thought to correspond with that which caused the\r\nuncontrolled blow out from well 6407/6-2, a small resistivity peak was\r\nrecorded, although the gamma ray reading remained constant. A negative drilling\r\nbreak was recorded at the same depth but here was no increase in gas. The well\r\nwas drilled with spud mud down to 459 m, with gypsum/polymer mud from 459 m to\r\n2470 m, and with gel/lignite/lignosulphonate mud from 2470 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Middle Jurassic sandstones were\r\npenetrated at 2461 m and were found to be gas/condensate bearing with a thin\r\nlight oil leg. From FMT pressure gradients, logs and shows on cores an OWC can\r\nbe set at 2583 m. There were shows and petroleum odour all through the\r\nreservoir down to 2583 m. Shows description, RFT pressure measurements, \u00A0DST\r\nresults and geochemical analyses indicated a gas/light oil contact at ca 257",
