GeneralWell 30/11-11 A is a geological sidetrack to well 30/11-11 S on the East flank of the Fensal Sub-basin in the North Sea. It was drilled to test the Viti prospect in a fault block separate from and to the east of the 30/11-11 S Madam Felle oil discovery. The primary objective was to test the hydrocarbon potential in the Middle Jurassic Tarbert Formation.Operations and resultsWildcat well 30/11-11 A Viti was kicked off by milling a window inside the 13 3/8" casing in well 30/11-11 S at a depth of 1092 m in the Hordaland Group claystone. The well was drilled to a total depth of 4016 m (3362.8 m TVD) in the Tarbert Formation. No significant problem was encountered in the operations. The well was drilled with XP07 oil-based mud from kick-off to TD.Top Brent Group, Tarbert Formation came in at 3796 m (3168.1 m TVD). All Brent Group reservoirs were water wet. No shows were seen in the well.Due to no discovery, no cores and no fluid samples were taken.The well was permanently abandoned on 7 April 2016 as a dry well.TestingNo drill stem test was performed.> -
