The area,\r\nknown as Haltenbanken, is a promising oil and gas province. It straddles two\r\nmajor Mesozoic structural features, the Trøndelag Platform and the Vøring Basin\r\nand lies along the western flank of the series of NNE-SSW faults, which\r\nseparate them. The well was drilled on the A-prospect and was designed to test\r\na major fault block. It was hoped to test oil bearing Middle Jurassic\r\nSandstone at approximately 3898 m with a secondary objective at the Early\r\nJurassic level.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Type Well for the Lysing\r\nFormation.\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 6507/7-1 was spudded with\r\nthe semi-submersible drilling rig Nortrym on 10 August 1984 and drilled to TD\r\nat a depth of 4825 in the Early Jurassic Tilje Formation. The well was drilled\r\nwith seawater and hi-vis pills down to 906 m, with gypsum/polymer mud from 906\r\nm to 3803 m, and with gypsum/lignite mud from 3803 m to TD. Few problems were\r\nexperienced whilst drilling the well. Some time was lost due to\r\ngumbo-associated problems. Mud was lost to formation while cementing the 13\r\n3/8" casing, resulting in the top of cement being lower than planned.\r\nHowever this did not affect the strength at the shoe, as it was possible to\r\nmake a good leak off test after drilling out. Tight hole problems were\r\nexperienced on a bit trip from 3716 meters, with over pull recorded on the\r\nmajority of subsequent trips. In addition a gain of 45 bbls of mud at 4360\r\nmeters indicated apparent under balanced conditions. Mud weight was\r\nprogressively raised from 11.2 ppg at 4081 meters to 12.6 ppg by 4360 meters in\r\nresponse to this problem. A further increase to 13.1 ppg was made at TD due to\r\nlogging difficulties associated with tight hole. The overall operation took 115\r\ndays from spud. Total depth was reached in 87 days, while an additional 28 days\r\nwere used to log, test and abandon the well. \u003c/p\u003e\r\n\r\n\u003cp\u003e",
