The well\r\nwas designed to test all potential reservoirs through the Permian on a closure\r\non a large, rotated fault-block. Primary objectives were Jurassic sandstones\r\nand secondary objectives were Paleocene sandstones.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWildcat well 16/1-2 was spudded with the\r\nsemi-submersible installation Ross Rig on 4 July 1976 and drilled to TD at 2919\r\nm in granite basement. Loss of circulation in high-porosity Zechstein\r\ncarbonates was the only significant problem encountered during the drilling of\r\n16/1-2. Initial drilling from the sea floor to 1286 meters was with sea water\r\nand gel. Below this depth a fresh water and lignosulphonate mud system was\r\nused.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well penetrated several sands in the Tertiary\r\nincluding the Utsira, Skade, and Grid formations. The Heimdal Formation was\r\nencountered at 2098 m with a 10 m zone of strong oil shows. The zone was\r\nhowever judged by log analysis to be water-productive and the shows not of\r\nsufficient quality to warrant testing. Triassic sandstones were originally interpreted to be water-filled. Later reinterpretation have confirmed the presence of oil in the Triassic interval. There were no shows from either the Zechstein or the Rotliegendes\r\nsandstone.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eNo cores were cut and no wire line fluid samples\r\nwere taken.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well was permanently abandoned on 7\r\nAugust 1976 as a dry well with shows.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eTesting\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eNo drill stem test was performed.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\r\n\r\n\r\n\r\n",
