It was drilled on\r\na salt induced anticlinal structure related to a salt pillow. The structure is\r\nwell defined from the Permian salt up to the upper cretaceous chalk. It has a\r\nvertical closure of 300 m for a closed area of 80 km2 at a seismic horizon\r\nassumed to be the Jurassic sandstone. A fault cuts the unconformably underlying\r\nhorizons attributed to Triassic. The specific objective of the 10/8-1 well was\r\nto test the hydrocarbon potential of the Jurassic sandstone section, estimated\r\nto be 60 m thick, with additional reservoir being furnished by the Triassic\r\nsandstones immediately below. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Type Well for the Skagerrak\r\nFormation and Reference Well for the Smith Bank Formation\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 10/8-1 was spudded with the\r\nsemi-submersible installation Pentagone 81 and drilled to TD at 2861 m in the\r\nLate Permian Zechstein salt deposits. The well was completed in 37 days without\r\nreported problems. The well was drilled with seawater with returns on the sea\r\nfloor down to 510 m, and with a LFC/sea water mud system from 510 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eOne thousand three hundred meter of\r\ncontinental deposits of Triassic age is present. On top of this is the Gassum\r\nFormation. The Early to Middle Jurassic was not encountered in the well. One\r\nhundred and fifty meter Late Jurassic sand and shale is directly overlying the\r\nGassum Formation. Around 200 m of shale was deposited during the Early\r\nCretaceous while the Late Cretaceous is represented by 425 m of lime mudstones.\r\nThe lower 200 m of the Tertiary was developed in mostly sandy facies. All\r\nFormations penetrated by the well were found water wet. The only show recorded\r\nwas traces of gas (C1 and C2) from 1010 m to 1050 m. Organic geochemical\r\nscreening analyses show TOC in range 0.1 - 1.5 % with the highest values in the\r\nLate Jurassic and Cretaceous sequences. The Tr",
