From tectonic model inferred\r\nin the area, the tectonic damage to the reservoir rocks was expected to be less\r\nthan previously encountered in the A-Central and the A-North areas. Movements\r\nalong the main fault during the Late Jurassic caused sedimentation of Triassic\r\nand / or Middle and Early Jurassic clastics of delta fan type. Source rock for\r\nB-II area was prognosed to be the mature part of the Spekk Formation. Possible\r\nshallow gas might be present some 30 - 40 m below sea level. One core would be\r\ntaken in each of the Garn, Ile and Tilje formations. The main objectives for\r\nthe well were to asses the reservoir quality and hydrocarbon potential of the\r\nGarn, Ile, and Tilje Formations and the Late Jurassic sequence; to obtain\r\nreservoir pressure; confirm the seismic and geological model; and to asses the\r\npresence of sands in the Early Cretaceous sequence.\u003c/p\u003e\r\n\r\n\u003cp\u003ePrognosed TD was 3700 m in the upper part\r\nof the Tilje Formation, or alternatively 4040 m in Triassic rocks.\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 6407/10-2 was spudded with\r\nthe semi-submersible rig Vildkat Explorer on 3 May 1990 and drilled to TD at\r\n3825 m in the Early Jurassic Tilje Formation sandstones. The well was drilled\r\nwith seawater and hi-vis pills down to1070 m and with KCl/Polymer/Polyacrylamide\r\nmud system from 1070 m to TD. In the 17 1/2" section 1070 to 2188 m mud\r\nfrom a previous well was used, below 2188 m fresh mud was used. Apart from some\r\ndifficulties during logging, drilling went on without any significant problems.\r\nNo shallow gas was encountered in this well. Apart from 8 m Lysing sand at 2378\r\nm there was no significant sand body development in the Cretaceous succession.\r\nThe Garn Formation was not present in the we",
