The primary target was\r\nDanian/Maastrichtian chalk/limestones. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eExploration well 2/8-5 was spudded with\r\nthe jack-up installation Zapata Explorer on 11 April 1974 and drilled to TD at\r\n3304 m in the Early Cretaceous Rødby Formation. Some problems with lost\r\ncirculation were experienced at 1618 m. At 1909 m in the Hordaland Group a gas\r\nkick was taken. Otherwise drilling went without significant problems.\u003c/p\u003e\r\n\r\n\u003cp\u003eNo sand was encountered in Paleocene. The\r\nwell penetrated 88 m of Danian chalk (Ekofisk Formation) and 380 m Late\r\nCretaceous chalk (Tor Formation) before marls of the Rødby Formation were\r\nencountered at 3264 m. Well logs indicated that all target formations were\r\nwater wet. Shows were reported as follows: \u003c/p\u003e\r\n\r\n\u003cp\u003eMiocene (1600 m to1722 m): white bright\r\nyellow amber fluorescence giving a fast yellow white slow cut. Associated with\r\na gas peak on the chromatograph analysis at the top. Patchy fluorescence was\r\nrecorded down section. Oligocene (1829 m): bleeding gas from limestone. (2353\r\nm): pale yellow fluorescence, slow cut, with acid only. Eocene (2464 m to 2718\r\nm): patchy shows, heavy brown oil stain, very dull amber to fast yellow\r\nfluorescence, occasional fast bright yellow cut, dark brown cut colour. The\r\nShetland Group (2796 m to 3264 m): background gas only, maximum of 1.8% C1,\r\ntrace C2-C4 at 3254 m. Fair oil stain, fair to good fluorescence and cut. \u003c/p\u003e\r\n\r\n\u003cp\u003eNo conventional core was cut and no fluid\r\nsample taken. The well was permanently abandoned on 23 May 1974 as a well with\r\noil shows.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n",
