The\r\nprimary objective was to evaluate sands at the base of the Jurassic sequence.\r\nThe structure is not associated with mobile salt, which is the case for the\r\nBream Discovery.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well is Reference Well for the\r\nFjerritslev 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 17/9-1 was spudded with the\r\ndrill ship Glomar Grand Isle on 16 September 1973. Initial drilling from the\r\nsea floor to 423 m was with seawater and gel. From the 20-inch casing shoe at\r\n409 m to TD a fresh water Spersene XP-20 mud system was used. The well was\r\ndrilled to 2816 m in Early Jurassic sediments when drilling operations were\r\nsuspended due to a severe storm. During this storm on November 6, the riser was\r\ndropped from the drill ship. During subsequent efforts the riser was broken\r\nleaving a riser stub approximately 13 m above the ocean floor. Due to this logs\r\nwere not run below 2616 m. \u003c/p\u003e\r\n\r\n\u003cp\u003eNo good reservoir sequence was\r\nencountered in the well. Some porosity was noted in cores from the formation\r\nunderlying the Sandnes Formation. No shows were recorded during drilling, and\r\nthe lack of hydrocarbons in 17/9-1 was confirmed by logs run in the re-entry.\r\nOrganic geochemical analyses showed excellent source rock quality in the Late\r\nJurassic interval from 2120 m to 2210 m with TOC in the range 2.5 % to 9.4 %\r\nand hydrogen index from 130 to 490 mg HC/g rock. The well is immature (%Ro\r\n<0.5) all through. Two conventional cores were cut in the intervals 2268 m\r\nto 2276.8 m and 2286 m to 2294.8 m. No fluid samples were taken.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was secured and temporary\r\nsuspended on December 23 as a dry hole.\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\r\n",
