The objective of this\r\nearly wildcat was to test all horizons down to the Rotliegendes, estimated at\r\n14100 ft (4298 m). Top Permian was expected at 10300 ft (3139 m). Planned TD\r\nwas at 15000 ft (4572 m).\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Reference Well for the\r\nÅsgard, Sola, and Rødby Formations.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell was spudded with the\r\nsemi-submersible installation on and drilled to TD at 4691 m in the Late\r\nJurassic Tyne Group. The well started to build angle from below ca 3500 m with\r\nmaximum 11 deg deviation at 4444 m. Otherwise no significant drilling problems\r\nwere reported from this deep well. The well was drilled water based down to\r\n3432 m and with an invert oil mud (Vertoil) from 3432 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Paleocene, Balder Formation, was\r\nencountered at 2590 m. Top chalks of the Shetland Group (Tor Formation) was\r\nencountered at 2635 m. In addition to shows from the gas detector, free oil was\r\nseen floating on the mud pits and samples showed good fluorescence and cut\r\nthrough the interval 2585 m to 2633 m (Balder, Sele, and Lista Formations).\r\nPost-well geochemical analyses reported significant oil staining down to 2776\r\nm. By testing live oil was confirmed in the uppermost Tor Formation. The tests\r\nwere inconclusive with regard to an OWC, but the logs indicated that the\r\ncontact was at 2655 m. Base Cretaceous was at 3555 m. The well did not reach\r\nPermian sediments; in stead the well drilled 1136 m in Late Jurassic shale\r\n(Mandal, Farsund and Haugesund Formations) before final TD was set. One\r\nconventional core was cut from 3864 to 3878 m in the Farsund formation.No wire\r\nline fluid samples were taken. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 3\r\nOctober 1969 as a minor discovery. After the 2/8-6 Valhall Discovery well was\r\ndrilled 6 years later well 2/11-1 was re-classified to oil appraisal well for\r\nthe Valhall Field.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTest",
