The eastern boundary of the Block 36/1 is only 20 km from\r\nnear-shore islands and, at the closest point, approximately 26 km from the\r\nmainland. Wildcat well 36/1-1 is located northeast of the Agat Discovery, on\r\nthe eastern side of the Norwegian Trench. The main objective and target was\r\nMiddle Jurassic sands.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eExploratory Well 36/1-1 was spudded with\r\nthe semi-submersible installation Dyvi Alpha on 9 May 1975 and drilled to a\r\ntotal depth of 1596 meters in metamorphic gneiss. The well was drilled without\r\nany serious drilling problems. The mud used was a water based salt-water gel /Milben\r\nmud down to 515 m, adding lignosulphonate and CMC from 515 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eSands were encountered in the Early\r\nCretaceous interval from 1219 m to 1359 m. The target Middle Jurassic\r\nsandstones were encountered at 1463 m and extended down to top basement at 1568\r\nm. Coal seams were found between 1500 m to 1548 m. No hydrocarbon bearing\r\nformations were encountered in the well. Minor quantities of hydrocarbon were\r\nrecorded in the Cretaceous and Middle Jurassic sections but there were no major\r\nshows. It was assumed that the structure on which 36/1-1 was drilled is not an\r\neffective trap. Possibly the shales overlying the Middle Jurassic sandstones\r\nare too poorly compacted to constitute effective seals. Also, the major\r\neasterly bounding fault may bring sands of the Cretaceous against the Middle\r\nJurassic, thus destroying the effectiveness of the trap. One 6.1 m (80 %\r\nrecovery) conventional core was cut at TD. No fluid sampling was attempted on\r\nwire line.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned as dry\r\non 14 June 1975.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo drill stem tests were conducted in\r\nthe Middle Jurassic: DST 1 from 1549.6 m to 1556 m and DST 2 from 1489.6 m to\r\n1496.6 m.
