It is thus\r\nlocated over the deepest part of the North Sea Tertiary Basin. The well was\r\nplanned to be drilled on the border between block 2/8 and block 2/9, the final\r\nwell position is actually in block 2/8.\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 2/9-1 was spudded with the\r\njack-up installation Zapata Explorer on 3 November 1972 and drilled to TD at\r\n3551 m in the Late Cretaceous Hod Formation. The well was drilled with a\r\nseawater and bentonite down to 387 m and with a polymer mud system with 1 % û 4\r\n% oil from 387 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe Rogaland Group was encountered at\r\n2962.7 m and consisted of the Balder, Sele, Lista, and Maureen formations.\r\nInterval 3065.7 m to Top Ekofisk Formation at 3092 m consisted of marl (Maureen\r\nFormation). From this point to TD the well drilled Late Cretaceous chalk\r\n(Ekofisk, Tor, and Hod formations). The best porosity in this sequence, based\r\non log analyses, was seen in the interval 3209.5 m to 3261 m in the Tor\r\nFormation was. However, no shows were recorded in the well. No fluid samples\r\nwere taken and no conventional core was cut. A wire line core slice was\r\nretrieved from 3499.4 m to 3500.3 m in the Hod Formation. The slice is\r\ndescribed in a report by Robertson Research. The well was permanently abandoned\r\nas dry on 7 December 1972.\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",
