It was programmed\r\nto test two primary sandstone prospects in the Late Paleocene. The lower\r\nobjective was the Hermod Formation and the upper objective was sandstones\r\nwithin the Balder Formation. The Hermod Formation prospect was a mapped\r\nisochron thick with a small area of structural closure at Top Sele Formation.\r\nThe Balder Formation prospect was mapped as an isochron thick with an associated\r\nseismic amplitude anomaly and was primarily regarded as a stratigraphic trap. \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 24/9-5 was spudded with the\r\nsemi-submersible installation West Delta on 7 December 1993 and drilled to TD\r\nat 2860 m in the Late Cretaceous Jorsalfare Formation. No significant problem\r\nwas reported from the operations. The well was drilled with seawater down to\r\n581 m, with KCl/PAC/PHPA from 581 m to 1941 m, and with KCl/PAC/PHPA/glycol\r\nfrom 1941 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Balder Formation was encountered at\r\n1964 m. A gross oil bearing Intra Balder Formation sandstone interval of 7.1 m\r\nwas encountered at 2011 m. Net sandstone was 6.3 m of which 5.9 m was in a\r\nsingle massive unit. Petrophysical analysis gave porosities of 35 - 40% in the\r\nmassive sandstone unit with an average SW of 22.2%. Base of the reservoir was\r\nencountered at 2018 m, which was found to be an oil-down-to water contact.\r\nSamples from the FMT tool indicated the reservoir fluid to consist of 32-34 deg\r\nAPI oil with a GOR of 91 Sm3/Sm3. Pressure gradient analysis gave a free water\r\nlevel at 2031.5 m (2028.0 m TVD). Geochemical analysis of the oil sample\r\nindicated minor biodegradation had taken place. The Sele Formation was\r\nencountered at 2031 m with 47 m net sandstone in two Hermod Formation sequences.\r\nThe upper sequence was encountered at 2049 m and the lower at 2098 m. These\r\nsandstones proved to be water bearing with no shows. A thin sandstone at 2045.5\r\n- 2047 m, just above the u",
