The hole was drilled on\r\nthe alpha-structure, a rotated fault block dipping towards south and west.\r\nJurassic and parts of Triassic is probably eroded. The primary objective of the\r\nwell was to test the hydrocarbon bearing potential of the previously undrilled\r\nalpha structure. The secondary objective was to verify geological model and\r\nstructural interpretation, to drill the third commitment well in the block, to\r\nimprove the paleontological, geological and geochemical understanding of the\r\narea. Planned TD was in Triassic sediments.\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 6507/8-3 was spudded with\r\nSmedvig Drilling semi-submersible installation West Delta on 3 September 1988\r\nand drilled to TD at 2075 m in Triassic rocks of the Åre Formation. The well\r\nwas drilled with spud mud down to 558 m, with CMC from 558 m to 1101 m, and\r\nwith gel/CMC/Ligno from 1101 m to TD. There was no shallow gas.

Top reservoir (Garn Formation) was\r\nencountered at 1358 m. It contained a small amount of gas with a gas/water\r\ncontact at 1362 m. FMT testing at 1361 m showed dry gas consisting of 99%\r\nmethane, interpreted to be of biogenic origin. Apart from this methane the well\r\nwas found to be dry based on cuttings, cores, and logs. Two cores were cut in\r\nthe well. Core 1 was cut between 1367 ? 1380 m (only the lower 1.5 m from the\r\nNot Formation recovered) and core 2 in the interval 1396 -1408 m in the Ile/Ror\r\nFormations.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was plugged and abandoned\r\ncompleted 20 September 1988 at as dry.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n\r\n",
