The well was to be drilled as a directional well in order to\r\npenetrate the two objectives.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eExploration well\r\n25/8-5 S was spudded with the semi-submersible installation "Dyvi\r\nStena" on 21 July 1994 and was drilled as a deviated well to a total depth\r\nof 3395 m (3040.7 m TVD RKB / 2887.7 m TVD SS), 57 m into late Triassic\r\n(Rhaetian) sediments of the Smith Bank Formation. The well was drilled vertical\r\ndown to 1204 m before starting to build angle. It was drilled with seawater and\r\nhi-vis pills down to 1215 m and with KCl / polymer / PAC / Glycol from 1215 m\r\nto TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eTop Heimdal\r\nFormation was penetrated at 2112.6 m (2050 m TVD SS) at an inclination of 33\r\ndegrees and an azimuth of 171 degrees and was found to contain oil. The\r\noil-water contact was estimated at 2158 m (2087 m TVD SS). The well found sands\r\nof the Vestland Group at 2836 m (2570 m TVD SS) water-wet and the second\r\nobjective, Statfjord Formation at 3040 m\r\n(2687.3 m TVD SS) water-wet. The inclination at top Statfjord was 53.6\r\ndegrees and azimuth 163.5 degrees. Top Triassic was correlated to be at 3338\r\n(2855.3 m TVD SS). The inclination was 55.2 degrees and azimuth 163.3 degrees\r\nat TD. The well was logged with LWD from 270 m to TD. The LWD included GR-Dual\r\nResistivity and Compensated Density/Neutron. Wire line logs were run from 1170\r\nm - 2291 m. Due to difficult hole conditions, it was not possible to run wire\r\nline logs below 2423 m. One core was cut in the Heimdal Formation from 2136 m\r\nto 2150 m and one core was cut in the Statfjord Formation from 3052 m to 3061\r\nm. A FMT fluid sample was taken at 2133.6 (2067 m TVD SS) m in the Heimdal\r\nFormation. The well was suspended on 22 September as an oil discovery (Jotun).\r\nIt was re-entered (25/8-5 S R) on 27 July 19",
