The objectives were to investigate\r\nPaleocene sand pinch out, the weathered top of the Cretaceous chalk and\r\nJurassic sandstone. The 16/3-2 well is a replacement for well 16/3-1, which was\r\njunked for technical reasons. \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 16/3-1 was spudded with the\r\nsemi-submersible installation Polyglomar Driller on 11 February 1976 and\r\ndrilled to TD at 2019 m in granite basement. No significant problems were\r\nreported from the operations. The well was drilled with spud mud (gel and lime)\r\nand pre-hydrated bentonite down to 440 m, and with lignosulphonate mud from 440\r\nm to TD. Around the well there was a 3 m deep and 15 m wide crater. Gas was\r\nobserved leaking from 2 main openings and 1 minor. The gas flow from one of the\r\nmajor openings was about 400 l/hour. The gas was practically pure methane\r\n(99.98%), probably coming from layers near the surface.\u003c/p\u003e\r\n\r\n\u003cp\u003eThere were no sands in Paleocene and the Cretaceous\r\nchalk was tight. A 20 m thick immature Draupne shale was encountered at 1955 m.\r\nThe well then encountered a 31 m thick late Jurassic sandstone from 1975 m to\r\n2006 m. Below this sandstone was a 9 m thick layer of weathered basement\r\noverlying the solid granite. The well proved to be water wet all through, and\r\nno shows were recorded.\u003c/p\u003e\r\n\r\n\u003cp\u003eThree cores were cut. Core 1 gave no\r\nrecovery, while core recovered 3.5 m core from the interval 1998 m to 2000.6 m\r\nin the Late Jurassic sand. Core no 3 was cut from 2017.5 m to 2019 m in\r\nbasement rock. No fluid sample was taken in the well.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 8\r\nMarch 1976 as a dry well.\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\r\n",
