The "Hod" anticline is a satellite or\r\nsubsidiary feature immediately to the southwest of the large Valhall structure.\r\nThe primary objective was the Danian/Late Cretaceous chalk section, the\r\nproductive horizon in surrounding fields. Paleocene sand/siltstones would be\r\nsecondary objectives, if encountered. These had shows in well 2/11-1, located\r\n6.4 km north.\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 2/11-2 was spudded with the\r\nsemi-submersible installation Zapata Explorer on 6 November 1974 and drilled to\r\nTD at 2806 m in the Early Cretaceous Rødby Formation. It was drilled in 37 days\r\nwithout major problems, although 10 days were lost due to waiting on water,\r\ncombating lost circulation after an attempt to kill a gas kick, and waiting on\r\na new BOP stack after a leak was found on the old equipment. The well was drilled\r\nwith seawater and Milben saltgel mud down to 145 m, with seawater, pre-hydrated\r\nMilben, Flosal mud from 145 m to 383 m, with Drispac/Flosal mud from 385 m to\r\n1295 m, with Shale Trol until gumbo, converting to a Unical/seawater mud from\r\n1295 m to 2660 m, and with a Unical/seawater mud from 2660 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eHigh gas readings were recorded from\r\napproximately 1415 m to 1675 m. Oil shows (dull yellow fluorescence and poor -\r\nfair cut) and free oil in the mud was also noted during the drilling of the\r\nabove interval. Oil bearing Santonian - Coniacian chalk (Hod Formation) was\r\nencountered at 2640.5.
