The Ula sands had\r\nbeen found hydrocarbon bearing in several wells in the surrounding blocks. Secondary\r\nobjective was Late Paleocene "Cod sands" (Forties Formation), which could\r\nbe present in the 1/3-6 area and could pinch out towards the diapir. The prognosed\r\nTD was 5030 m below MSL. The "Cod sands" were considered a\r\nlow-probability target.\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 1/3-6 was spudded with the\r\nsemi-submersible installation Dyvi Stena on 11 March 1991. Drilling performance went on without significant problems but the primary target of the well was\r\nnot reached. The discovery of a significant hydrocarbon-bearing reservoir in\r\nthe Paleocene activated the contingency measures of the programme (to set an\r\nextra 11 3/4" liner). For safety and technical reasons, and to allow for a\r\nproper test of the Paleocene, the well was stopped at 3586 m in the Late\r\nCretaceous Hod Formation. No shallow gas was encountered while drilling. The\r\nwell was drilled with a KCl polymer mud.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well encountered 85 m of hydrocarbon\r\nbearing Forties sands at 2913.5 m. The pay zone was 44 m thick with a\r\nhydrocarbon saturation of 56 %. No hydrocarbon-water contact was found. Apart\r\nfrom the hydrocarbons in the Forties sands oil shows were also recorded from\r\n3519 to 3530 m in the Tor Formation.\u003c/p\u003e\r\n\r\n\u003cp\u003eOne conventional core was cut at 2921 m\r\nto 2928.5 m in the Forties sands. Segregated fluid samples were taken at three\r\ndepths: 2923 m (filtrate and gas), 2937 m (filtrate and gas), and two samples\r\nat 2973.5 m (filtrate and gas in one and filtrate only in the other).\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 22 June 1991 as a gas-condensate discovery.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThree DST tests were p",
