The objectives of the well\r\nwere to test the sandstones of Late/Middle Jurassic age, the Sandnes- and Bryne\r\nformations. Furthermore the 9/2-3 well will test the geophysical and structural\r\ninterpretation of the area and improve the paleontological, geological and\r\ngeochemical understanding of this area in the North Sea. A strong reflector was\r\nobserved at 253 m, but was expected to be a change in lithology rather than\r\nshallow gas.\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 9/2-3 was spudded with the\r\nsemi-submersible installation Vildkat Explorer 4 December 1989 on and drilled\r\nto TD at 3424 m in the Middle Jurassic Bryne Formation. No shallow gas was\r\nencountered in this well. Drilling went on without significant difficulties.\r\nThe well was drilled with seawater/gel/bentonite down to 376 m, with\r\ngypsum/polymer mud from 376 m to 3210, and with a polymer/Resinex mud from 3210\r\nm to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe Sandnes Formation was encountered at\r\n3252 m and proved oil. The OWC was difficult to place from the logs, but was\r\nestimated at 3273 m. This gives a 21 m oil column. Gross reservoir interval was\r\nfound to be 115 m. Core and log analysis indicate a fairly low porosity\r\nsandstone with small amounts of silt, shale and limestone (calcite cement). The\r\nBryne Formation proved to be water bearing, and no test was performed in this\r\nformation. \u003c/p\u003e\r\n\r\n\u003cp\u003eOrganic geochemical analyses show that\r\nthe Tau Formation (3098 m to 3188 m) is an excellent source rock with TOC in\r\nthe range 3 to 13 % and hydrogen index in the range 360 to 700 mg HC/g TOC. The\r\nTau Formation is early oil-window mature (%Ro around 0.6 and Tmax from 430 to\r\n435 deg C) in the well. Analyses of the DST oil show a somewhat higher maturity\r\nthan the in-well source rock. Furthermore, the oil showed a close resemblance\r\nto the 9/2-1 DST 3 oil. \u003c/p\u003e\r\n\r\n\u003cp\u003eOne conventional core was cut in the\r\nSandnes formation in the interval 326",
