The primary target were the Late Jurassic Sognefjord and the Upper Jurassic Fensfjord formations.\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 36/7-2 was spudded with the\r\nsemi-submersible installation West Vanguard on 2 September 1997 and drilled to\r\nTD at 1435 m in basement rock. An anchor test was performed after setting the\r\n13 3/8" casing shoe. Anchor no. 2 and 3 failed the test to 180 ton and\r\nslipped at 170 ton. Piggyback anchors were set on anchor no. 2, while main\r\nanchor no. 3 was lost. Fishing for the anchor chain was delayed 47.5 hrs due to\r\nbad weather. The anchor chain was retrieved and the anchor reset with two piggy\r\nbacks. Both anchors then stood a successful test. The well was drilled with\r\nseawater and hi-vis pills down to 591 m and with ANCO 2000 from 591 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well discovered heavily biodegraded\r\noil in the Middle Jurassic deltaic sandstone reservoir of the Fensfjord\r\nFormation. The overlying Sognefjord Formation sands were tight and contained no\r\nhydrocarbons. A 32.5 m oil column was proven from 931.5 to ca 964.0 m. The\r\nexact level of the oil-water contact could not be determined as it was in a\r\nshaley zone. Oil shows on cuttings were recorded from 915 m down to 1045 m. The\r\nreservoir zone of the Fensfjord Formation was divided into two units, from\r\nwhich only the upper had good reservoir properties. \u003c/p\u003e\r\n\r\n\u003cp\u003eNo conventional cores were cut, but 60\r\nsidewall cores were taken from 603 to 1408 m with a recovery of 56 samples. The\r\nMDT tool was run and 23 good pressure points were acquired in addition to a\r\nfluid sample at 934.5 m. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was completed on 22 September\r\n1997 as an oil discovery.\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",
