It is situated on a separate but\r\nrelated structure to 6407/1-2, which found gas-condensate in the Middle\r\nJurassic Garn Formation. The primary target of well 6407/1-3 was Middle\r\nJurassic sandstones. Secondary target was Early Jurassic sandstones. Other\r\nzones of interest were the Late and Early Cretaceous and the coal unit in the\r\nEarly Jurassic. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Type Well for the Brygge\r\nFormation and Reference Well for the Hordaland Group, it is Type Well for the\r\nGarn Formation, and it is Reference Well for the Ile and Not Formations.\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 6407/1-3 was spudded with\r\nthe semi-submersible installation Dyvi Delta on 17 September 1983 and drilled\r\nto TD at 4469 m in Late Triassic sediments of the Åre Formation. Hole problems\r\noccurred when running back in the hole after a period of bad weather. The hole\r\nhad collapsed and had to be reamed back to bottom at 3136 M. A drilling break\r\noccurred at 3746 to 3748 m. All in all, there was a total of 16 days downtime\r\ncaused by bad weather. Still, the well was drilled 22 days faster than\r\nprognosed. This was mainly due to fast penetration in the 17 1/2" and\r\n6" hole, an efficient coring operation and favourable weather conditions\r\ncompared to well 6407/1-2. The well was drilled with seawater/gel down to 948\r\nm, with lignosulphonate/gypsum from 948 m to 3608 m, and with bentonite gel\r\nfrom 3608 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eHydrocarbon bearing Middle Jurassic\r\nsandstones (Garn Formation) were encountered at 3600 m. A gas cap extended to\r\n3687.5 m followed by an oil zone down to 3709 m. At this point the sand grades\r\nrapidly into the underlying silt and clay of the Not Formation at 3709.5 m.\r\nThis makes it difficult to conclude on an OWC for the discovery. The Nise\r\nFormation from 2448 m to 2601 m had good gas shows whilst drilling and oil\r\ncontamination of drilling mud. Mud log data suggested a possibl",
