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. The secondary objective had been fulfilled by drilling of the\r\nprimary entry 6610/3-1, which was temporarily abandoned in February 1993 due to\r\nproblems induced by severe weather conditions. The re-entry was done to fulfil\r\nthe primary objectives.\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 6610/3-1R is the re-entry of\r\nwell 6610/3-1. It was entered with the semi-submersible installation Ross Isle\r\non 15 September 1993 just below the 13 3/8" casing shoe in well 6610/3-1\r\n(kick-off point at 1750 m in intra-Tang sandstone). Well 6610/3-1R was drilled\r\nto TD at 4200 m in the Triassic Red Beds. No significant technical problems\r\nwere encountered during drilling. The well bore was drilled with ANCO 2000 mud\r\nfrom kick-off to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Tilje Formation was encountered from\r\n3771 m to 3935 m with sandstone interbedded with siltstone and with limestone\r\nand claystone stringers. The sandstone was mostly fine-grained and mostly\r\nsilica and calcite cemented. An FMT pressure log was run, but no gradient could\r\nbe established due to tight/impermeable Formation. The well penetrated three\r\nsource rock formations: the Spekk Formation (3534 m to 3614 m), the Melke\r\nFormation (3614 m to 3705 m, and the Åre Formation coals (3935 m to 4147 m).\r\nModerate to minor shows of unproducible character were detected at scattered\r\nintervals in the Lange Formation. These were indicated by wet gas occurrences,\r\nsediment extracts and oil recovered through mud injection in a test interval.\r\nTrace shows were also recorded on claystones/limestones and silty layers in the\r\nSpekk and Melke Formation. No producible oil or gas was en",
