It was intended to be the first well\r\nto test the reflections below the Base Cretaceous (Kimmeridgian) Unconformity\r\non a seismically defined, northerly trending west-northwest dipping fault\r\nblock. The well was located near the apex of the structure at the Base\r\nCretaceous level, but down-dip with respect to deeper stratigraphy. Primary\r\ntargets were the Middle Jurassic Brent Formation and the Early Jurassic/Triassic\r\nStatfjord Formation. Secondary targets were possible Early Tertiary and Late\r\nJurassic sandstones. Planned TD was 4300 m Sub Sea. \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 34/2-2 R was spudded with the\r\nsemi-submersible installation Sedco 703 on 12 December after the first entry\r\n34/2-2 had been abandoned for technical reasons. The well was drilled to TD at\r\n4074 m in the Late Triassic Statfjord Formation, Raude Member. Bad weather\r\nconditions during wintertime delayed the drilling progress on many occasions. While\r\ndrilling the 36" hole section some problems were encountered due to\r\nboulder beds. An abnormally high wave hit the rig on 16 January, damaging the\r\nliving quarters. The rig had to be shut down for repairs for eleven days.\r\nOtherwise, drilling of the sedimentary sequence below the 30" casing to TD\r\ndid not cause major problems. The well was drilled with spud mud/hi-vis pills\r\ndown to 499 m, with CMC and bentonite from 499 m to 810 m, and with\r\nlignosulphonate mud from 810 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe Brent Formation was not developed in\r\nthe well and the reservoir conditions in the Statfjord Formations were found to\r\nbe poorer than expected. No indications of hydrocarbon accumulations were seen.\r\nTrace shows were recorded in the Cretaceous in sandstone stringers from 2405 m\r\nto 2700 m, in siltstones from 2903 m to 3000 m, and in sandstones from 3200 m\r\nto 3282.5 m. From 3282.5 m to 3297.5 m there was a good show in a limestone\r\nbed. No oil shows were reported ",
