It is the\r\nreplacement well for 15/6-1, which was junked for technical reasons. The objective\r\nwas to evaluate a deep-seated structure in the Scottish-Norwegian Graben. The\r\ntarget was Eocene to Paleocene sandstones.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWildcat well 15/6-2 was spudded with the drill\r\nvessel on 9 September 1971 and drilled to TD at 3131 m in the Shetland Group. No\r\ndrilling problems were encountered, however, due to deviation problems around 1311\r\nm a planned FIT was aborted, as the tool would not go beyond this depth. Initial\r\ndrilling from the sea floor to 1330 m was with seawater and gel. Below 1330 m,\r\na fresh water Spersene XP-20 mud system was used. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe Paleocene section contained abundant\r\npotential sandstone reservoirs (Heimdal Formation) with thin beds of clay\r\nbecoming marly below 2390. Significant shows were encountered in the interval 2223\r\nto 2236 m in the upper Heimdal Formation. The cuttings, sidewall and\r\nconventional cores corroborated the shows. Weak shows were recorded also on\r\nnumerous sidewall cores between 2303 and 2604 m. However, other evidence did\r\nnot substantiate these shows and the reservoir was assumed water wet below 2236\r\nm. The Danian (2676 to 2735 m, Våle Formation) consisted of a sequence of\r\nthinly interbedded sandstones, clays, shales and chalky limestones. No shows\r\nwere reported in this section. The Late Cretaceous section, from 2735 m to 3106\r\nm, was predominantly limestone with thin interbeds of shale. Thin interbeds of\r\nsandstone were also noted. There were no shows in the Late Cretaceous.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThree cores were cut.
