The\r\nmain objective was to test the hydrocarbon potential in the Early Jurassic\r\n(Tilje Formation) sandstones. A secondary objective was to test the possibility\r\nof development of sandy fans from Early Tertiary (Paleocene) to Early\r\nCretaceous.\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 6610/3-1 was spudded with\r\nthe semi-submersible installation Deepsea Bergen on 29 October 1992 and drilled\r\nto TD at 3126 m in the Late Cretaceous, Lange Formation. Caving bridges caused\r\nwire line tools to hang-up and the severe weather conditions magnified the hole\r\nstability problems by the rig being disconnected several times. Due to long periods\r\nof wait on weather and upcoming drilling restrictions the decision was made to\r\ntemporarily plug and abandon. No logs exist from seabed to 402 m. The intervals\r\n402 m to 919 m and 2877.5 m to 3126 m were logged with MWD only. The well was\r\ndrilled with seawater and hi-vis pills down to 938 m and with gypsum/pac mud\r\nfrom 938 m to TD\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well encountered sandy fans of\r\nPaleocene and Late Cretaceous age. Shows were recorded in Intra Nise Sandstone\r\nat 2282 m to 2320 m, in Lysing sandstone from 2661 m to 2680 m, and in thin\r\nlimestone stringers in the Lange Formation at 3073 m and at 3167 m. FMT\r\npressure points gave water gradients in all reservoir sequences. Organic\r\ngeochemical analyses confirm good, scattered oil shows in Intra Nise sandstone\r\nfrom 2293.75 m to 2309.45 m. The shows were characterised as severely\r\nbiodegraded stains in an irregular pattern with no obvious relation to\r\nlithology. The other shows recorded while drilling were not confirmed by these\r\nanalyses, but they revealed an additional weak show on a sample from an intra\r\nTang Formation sandstone at 1675 m as well as a trace of oil in the FMT water\r\nsample from 1645 m.
