Operations went smoothly with\r\nlittle downtime. The well was drilled with seawater and viscous pills down to\r\n966 m and with KCl/PHPA/PHB/PAC mud from 966 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eTraces of oil were seen in reservoir\r\nquality sandstone units within the Paleocene Lista Formation. No FMT samples\r\nwere taken and no detailed petrophysical analysis was carried out at this\r\nlevel. Good hydrocarbon bearing sandstones were found in the Late Jurassic\r\nSognefjord Formation from 1796 m. From FMT and log data the gas-oil contact is\r\nat 1800.5 m and the oil-water contact at 1851.5 m with a gross hydrocarbon\r\ncolumn of 31.7 m. The Middle Jurassic Fensfjord Formation was found to be water\r\nwet with no shows. The Brent Group from 2423.5 m has a gross hydrocarbon column\r\nof 58.1 m. From FMT and petrophysical analysis a gas-oil contact is present at\r\n2469.9 m and an oil-water contact at 2504.8 m. A total of eleven cores were cut\r\nin the Late and Middle Jurassic reservoirs. Five consecutive cores were taken\r\nin the Sognefjord Formation with 93 m cut and 95% recovered. Six cores were cut\r\nin the Brent Group (Ness through to Oseberg Formations), with 113 m cut and\r\n98.8 % recovered. FMT measurements indicate moderate to good permeabilities in\r\nthe Sognefjord Formation and Brent Groups. Eight segregated samples were taken,\r\nproving gas and oil in the Sognefjord Formation and gas and condensate in the\r\nBrent Group.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 1",
