It was drilled to evaluate the hydrocarbon potential of both\r\nthe Late Jurassic and the Triassic sandstone formations. Main target was the Late\r\nJurassic Ula Formation found oil bearing in the Ula field, 17 km to the NW, and\r\nin the well 2/1-3. Secondary target was the Triassic sandstone found oil\r\nbearing in the well 7/12-6 in the Ula field. \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 1/3-3 was spudded with the\r\nsemi-submersible installation Borgsten Dolphin on 22 August 1982 and drilled to\r\nTD at 4876 m logger's depth (4867 m driller's depth).

The Chalk Group was 686 m thick. Less than 10 m of sandstones\r\nscattered in several thin layers were encountered and partially cored in the\r\nFarsund Formation, they were found tight. The Late Jurassic Ula Sandstones,\r\nwhich were the main objective, were found at 4178 m and they were oil bearing\r\ndown to an OWC at 4221 m, but with only ca 5 m pay zone. The upper half with\r\nthe best reservoir qualities was cored (cores 2 to 6). The coaly Bryne\r\nFormation is assigned at 4527 m, top Triassic Smith Bank Formation at 4620 m,\r\nand the Zechstein evaporitic rocks, anhydrite (26 m) and halite was penetrated\r\nfrom 4820 m to TD. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eResidual hydrocarbon saturation based on\r\nelectric logs were seen in the Paleocene at 3068 to 3093 m and in top Triassic\r\nat 4622 to 4637 m.
