The primary purpose was\r\nto find hydrocarbon accumulations of significant amounts in the Middle and\r\nEarly Jurassic sandstone reservoirs. Secondary objectives were to check for\r\nhydrocarbon accumulations deeper than the structural closure of the main field.\r\nThe well should also verify the geophysical and structural interpretation and improve\r\nthe geological, paleontological and geochemical understanding of the area.\r\nTotal depth was to be in rocks of Triassic age or 4000 m in order to satisfy\r\nthe licence commitment.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 6506/12-7 was spudded with the\r\nsemi-submersible installation Dyvi Delta on 7 April 1987 and drilled to TD at 4840 m in the Early Jurassic Tilje Formation. Drilling proceeded without\r\nsignificant problems. The well was drilled with spud mud down to 597 m, with\r\ngypsum/polymer mud from 597 m to 4427 m, and with a pre-hydrated\r\nBentonite/Lignosulphonate mud system from 4427 m to TD. No shallow gas was\r\nencountered.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe first show appeared in the Lange\r\nFormation at 3791 - 3794 m. During coring there were oil shows in Garn and Ile\r\nFormations, while Ti1je only contained small traces of oil. Both cores and logs\r\nindicated that Garn and Ile Formations were hydrocarbon bearing down to ca 4538\r\nm, while Ti1je Formation was indicated to be water bearing. The porosity was\r\nassumed to be between 8 and 12 %. Mobil wanted to test the Ti1je Formation to\r\nget a fluid sample to understand the logs better. This was a wise decision\r\nbecause the formation produced oil at very good rates. The Garn Formation on\r\nthe other hand did not produce any formation fluid when tested. The oil/water\r\ncontact in the Tilje Formation was not found because the logs did not give\r\nclear data. \u003c/p\u003e\r\n\r\n\u003cp\u003eEight cores were cut in the well with a\r\ntotal recovery of 62.6 m core.
