This early wildcat\r\nwell had the general objective to: " -test the hydrocarbon potential and\r\ninvestigate the lithology in this portion of the North Sea basin".\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Type Well for the Utsira\r\nFormation.\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 16/1-1 was spudded with the\r\nsemi-submersible installation Ocean Traveler on 26 September 1967 and drilled\r\nto TD at 3203 m in the Late Cretaceous Hod Formation. No significant problems\r\nwere reported from the operations. Initial drilling from the sea floor to 392 m\r\nwas with seawater and gel without casing. Returns were to the sea floor. Below\r\n392 m to total depth, a seawater slurry with Bentonite, Zeogel, Spersene,\r\nXP-20, Caustic Soda, and 0-12% diesel oil was used.\u003c/p\u003e\r\n\r\n\u003cp\u003ePorous sandstone was observed in the\r\nMiocene, Oligocene, and Eocene. There were also Paleocene sands in the well.\r\nTraces of possible residual oil stain were encountered in cuttings and cores\r\nfrom the Oligocene and Eocene. In addition, questionable shows (non-fluorescent\r\ndead oil) were reported on cores from the Paleocene. However, neither the hot\r\nwire gas indicator nor chromatograph suggested the presence of hydrocarbons. \u003c/p\u003e\r\n\r\n\u003cp\u003eA total of 18 cores were cut from the\r\ndifferent formations within the Hordaland, Rogaland, and Shetland Groups,\r\nrecovering a total of 171 m core. The depth for core 2 is probably incorrect,\r\npossibly be five meter shallow due to malfunction of the bumper subs. FIT wire\r\nline fluid samples were taken in potential hydrocarbon-yielding beds at 1878.5\r\nm, 2532.9 m, and at 2592.3 m. Only water and mud were recovered. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 10\r\nDecember 1967 as a dry well.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed.\u003c/p\u003e\r\n\r\n\r\n",
