The block was awarded in License 56 in 1979. The first well in the\r\nLicense (34/2-1) was spudded on 29 December 1979 and junked and abandoned on 19\r\nFebruary 1980 at 850 m, due to technical problems. As the first well did not\r\nsatisfy License commitments, it was agreed among the partners that Well 34/2-2\r\nwould be drilled at the same location with the same objectives. This well was\r\ndrilled to 4074 m and plugged and abandoned after having found poor reservoir\r\nconditions and no hydrocarbon accumulations. Well 34/2-3 was drilled 3.25 km to\r\nthe northwest of Well 34/2-2 on the northern end of the Tampen Spur. The main\r\nobjective was to test the sedimentary section below the Base Cretaceous\r\nUnconformity in a seismically defined northeasterly trending horst block.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was spudded with the\r\nsemi-submersible installation SEDCO 703 on 15 May 1981. Due to boulder beds at\r\nthe location the first 36-inch interval was unsuccessful. The well was\r\nrespudded on 17 May 1981 and drilled to TD at 3742 m in the Late Triassic Lunde\r\nFormation. The well was drilled with spud mud down to 815 m, with\r\ngypsum/lignosulphonate from 815 m to 3340 m, and with\r\ngel/chemtrol/lignosulphonate from 3340 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eWhile drilling between 820 m and 890 m\r\nshallow gas was encountered, giving readings of up to 7% total gas.
