The well was positioned crestally\r\non the southern tip of a big, seismically defined, horst feature. This horst,\r\ntrending N-S and sharply limited by faults on west, east and south sides, has\r\ninduced a vast anticline in his Mesozoic and Tertiary overburden. The well was\r\nprogrammed to investigate the sedimentary section down to pre-Permian\r\nformations.\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 16/6-1 was spudded with semi-submersible\r\ninstallation Ocean Viking on 7 November 1967 and drilled to TD at 2061 m in\r\nbasement rock. The well was drilled with seawater down to 360 m, and with a\r\nseawater / Q'Broxin / CMC type mud from 360 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eGas shows (C1) were observed with a GAL\r\n21 type chromatograph while drilling the Tertiary series, mainly in the upper\r\npart with a maximum of 12 % at 630 m, decreasing to 2-3 % below 790 m. In the\r\nCretaceous, no gas was seen and only a very small show (0.02 %å was recorded at\r\nthe top of Jurassic shale. In the Utsira Formation 28 m net sand was\r\nencountered. The sands had high porosities, but were water wet. From 2019 m\r\nto2050.5 m a very rich Draupne source rock shale with 6 % to 7 %\u00A0 TOC was\r\npenetrated. The sequence is immature in the well position. At 2050.5 m 4.5 m of\r\nlithic sand was found directly overlying basement. The sand is probably a\r\nbasement "wash" which reflects the transition from an erosive stage\r\nto a depositional one. The lower 4 m of this sand had very good porosities (>32%)\r\nbut were also water saturated. Permian and Triassic objectives were not present\r\nin the well. One core was cut in basement from 2057 to 2060.5 m (TD) with 100 %\r\nrecovery. Two series of log-operations were run at 1362 m and 2060.5 m. Trouble\r\noccurred with gumbo type clay bridging the hole during the first operations and\r\nthree cleaning trips were necessary. No fluid samples were attempted.
