It was estimated that at Paleocene depth there would be\r\n12 square miles of closure with 150 m vertical relief and at Jurassic depth, 9\r\nsquare miles of closure with 370 m vertical relief. The principal objective\r\nhorizons were the Jurassic and Paleocene sands.\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 16/11-2 was spudded with the\r\nsemi-submersible installation Ocean Viking and drilled to TD at 2378 m in Late\r\nPermian Zechstein salt. \u003c/p\u003e\r\n\r\n\u003cp\u003eNo Paleocene sands were encountered. As\r\nexpected the Danian Chalk section was missing in the well. The Upper Cretaceous\r\nLimestone was tight with no shows. The Jurassic sand top was encountered at\r\n2202 m with the main sand development beginning at 2207 m. The net sand\r\nthickness was 35 m, but on testing was found to be tight and unproductive. The\r\ntotal Jurassic section was about 244 m thinner than anticipated. The Triassic was\r\nmissing. An 11.5 m Dolomite section was developed from 2250 m to 2261.5 m at\r\nthe top of the Permian succession. This was also tested, but found to be tight\r\nand unproductive. Thus the well was terminated in the Zechstein higher than\r\nplanned. Except for the reduced Jurassic sequence and absence of Triassic\r\nsediments causing the higher position of the Zechstein, the structure and\r\nstratigraphy were as predicted in the prognosis. Geochemical analyses of shales\r\nfrom the Late Jurassic Tau Formation proved excellent source potential, but the\r\nkerogen is immature to marginally mature in the well location. No cores were\r\ncut. The well was permanently abandoned as a dry well on 23 July 1973.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo intervals in the Sandnes Formation\r\nwere perforated and tested, 2261 m to 2251 m and 2242 m to 2231 m. Both\r\nintervals were found tight and unproductive and no hydrocarbons were produced\r\nduring the tests.\u003c/p\u003e\r\n\r\n\r\n",
