Well 6407/10-1 is located immediately to the south of the Njord\r\nField in block 6407/7, on compartment B1 of the B-structure. The B-structure is\r\ndown faulted relative to the Frøya High in south-southeast and to the\r\nA-structure in block 6407/7 to the west. The structure is dipping into a small,\r\ndeep basin to the north. The main objectives of the well were to test\r\nhydrocarbon potential of the Garn, Ile and Ti1je Formations in the B-structure.\r\nFurther objectives were to test the geological model and to calibrate the\r\nseismic interpretation and horizon identification. The well location was chosen\r\nto penetrate the target reservoir with an up-dip of less than 15-30x10 6 sm3\r\noil in place, and to penetrate the Tilje Formation within the expected depth\r\nrange of the oil-water contact in the Ti1je Formations in the A-structure.\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 6407/10-1 was spudded 7 may\r\n1987 by Polar Frontier Drilling semi-submersible rig Polar Pioneer and drilled\r\nto TD at 3347 m in the Triassic Grey Beds. Due to a shallow gas risk, the well\r\nwas drilled without riser and logged with MWD down to 1100 m. The prognosed\r\nshallow gas levels were drilled without problems and only small peaks on the\r\nlog indicated sand with a certain gas saturation. The 20" casing was\r\nskipped and 13 3/8" casing was set directly. The well was drilled with\r\nseawater and hi-vis pills down to 1117 m and with KCl mud from 1117 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was water bearing with a\r\npossible small amount of gas in the upper part of Ti1je Fm. Some shows were\r\nrecorded in the Ile Formation. The Formation pressures encountered showed that\r\nthe A and B compartments of the Njord Field are not in communication. Five\r\ncores were cut in the intervals 2582 - 2610 m (Rogn Formation), 2748 - 2776 m\r\n(Not Formation), 2817 - 2845 m (Ile Formation), 2845.5 - 2873.5 m (Ile / Ror\r\nFormation), and 2983 - 3011 m (Tilje Formation).\u003c",
