The well was drilled\r\nwith seawater and hi-vis pills down to 814 m and with gypsum/polymer mud from\r\n814 m to TD. No significant problems were encountered during drilling. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe lithology of the well corresponded\r\nvery well with that of well 34/2-2 R with no significant sandstones down to the\r\nLower Jurassic Cook Formation. The primary objective, a distal facies of the\r\nMiddle Jurassic Brent sandstone, was not seen in this well. Instead, a\r\nclaystone/shale sequence belonging to the Heather Formation was penetrated.\r\nSecondary target sandstones of the Lower Jurassic Cook and Statfjord Formations\r\nwere drilled proving water wet. Weak oil shows were seen between 3030 m and\r\n3740 m, with the most prominent shows in the 3245-3580 m interval. Oil shows\r\nwere generally associated with thin sandstones and siltstones in a generally\r\nargillaceous section. Occasional thin limestone and/or dolomite stringers also\r\nprovided oil indications. Geochemical analyses detected possible migrated\r\nhydrocarbons also in the Cook Formation. One core was cut with 58% recovery in\r\nthe interval 3827 m to 3846 m. No wire line fluid samples were taken. The well\r\nwas permanently abandoned as dry with weak shows on 11 June 1985.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n\r\n\r\n",
