It was designed to test\r\npossible hydrocarbon accumulations in a seismic closure (Zeta-structure) in the\r\nsoutheastern part of the block. The primary objective of the well was\r\nsandstones of Middle Jurassic age. Secondary objectives were clastics of lower\r\nJurassic and Upper Triassic age.\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 7119/12-2 was spudded with\r\nthe semi-submersible installation Ross Rig on 16 April 1981 and drilled to TD\r\nat 1902 m in the Late Triassic Fruholmen Formation. Boulder clays in the top\r\n36" hole caused low rate of penetration and considerable difficulties in\r\nsetting the 30" casing. Gas sands were encountered in the interval from\r\n404-410 m. The 20" casing was set above this sands instead of the planned\r\nsetting depth at 600 m. Due to high gas readings and increasing pore pressure,\r\nthe drilling below 20" casing could not continue to planned 13 3/8"\r\ncasing depth. Hence a 16" liner was set at 590 m. While underreaming below\r\nthe liner, the underreamer failed to close and consequently could not be pulled\r\nto surface. The underreamer was left in the hole and the well sidetracked at\r\n1215 m. The well was plugged back and the BOP-stack pulled when gas bubbles\r\nwere observed coming out of the wellhead. To cure this problem the BOP-stack\r\nwas installed again and previously set cement plugs drilled out to 275 m. A\r\npacker was set inside the 20" casing at 273 m and no more gas was seen coming\r\nfrom the well head. The well was then plugged back and abandoned. The well was\r\ndrilled with spud mud down to 394 m and with gel/lignosulphonate/seawater from\r\n394 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eMiddle Jurassic to Late Triassic\r\nsandstones with good reservoir properties were encountered from 1372 m to TD.\r\nDrill cuttings and extensive coring had oil shows throughout, but RFT pressure\r\ngradients as well as logs and DST proved 100% water ",
