The primary objective\r\nwas to confirm hydrocarbon reserves in the Brent Group in this discovery.\r\nSecondary objective was to test the Early Jurassic Statfjord and Cook\r\nFormations. A third objective was to investigate properties of the Lista\r\nFormation of the Rogaland Group, which had significant shows in 34/11-1.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 34/11-3 was spudded with the\r\nsemi-submersible installation Deepsea Trym on 1 August 1996 and drilled to TD\r\nat 4482 m in the Early Jurassic Statfjord Formation. When drilling 8 1/2"\r\nhole at 4032 m a kick situation was experienced. A total of 23.8 days was spent\r\nbefore the operation could be continued. After drilling to TD problems occurred\r\nwith the BOP connector. A cement plug was set and the well suspended for\r\nrepairs of the connector. When drilling out the cement plug the well was\r\nunintentionally sidetracked at 4009 m. 34/11-3T2 was drilled to final TD at\r\n4230 m (4234 m loggers depth). The well was drilled with bentonite and seawater\r\ndown to 1115 m, with ANCO-2000 mud from 1115 m to 3985 m, and with ANCO THERM\r\nmud from 3985 m to TD (including sidetrack).\u003c/p\u003e\r\n\r\n\u003cp\u003eNo shows were observed in cuttings from\r\nthe Rogaland Group, but in core 1 thin sandstone laminae with weak shows were\r\nobserved. The top of the Brent Group was penetrated 14.5 m shallower than\r\nprognosed, and was proven to be gas/condensate bearing down to 4196.2 m. No GWC\r\nwas found. No visual shows were observed in the Cook Formation.\u003c/p\u003e\r\n\r\n\u003cp\u003eIn the Statfjord Formation, weak shows\r\nwere seen, and a weak HC odour from the core was noted.\u003c/p\u003e\r\n\r\n\u003cp\u003eAll conventional cores were cut in the\r\noriginal hole while all reservoir logging was performed in the sidetrack. Only\r\nMWD logs exist from the lower part of the original hole. A total of 101.8 m\r\nconventional core was recovered in 12 cores. Core 1 was cut from 2027 m to\r\n2035.6 m in the Lista For",
