Wellbore history
GeneralWell 30/3-2 is located ca 7 km north of the Oseberg Field in the Northern North Sea. The primary objective of the well was to test sandstones belonging to the Brent and Dunlin group. Secondary objective was sandstones in the Statfjord formation.Operations and resultsWildcat well 30/3-2 was spudded with the semi-submersible installation Deepsea Saga on 4 July 1980. Due to a strike beginning at July 13 drilling was temporary abandoned at 955 m in Miocene sediments of the Hordaland Group. The well was drilled with pre-hydrated gel.No cores were cut and no wire line fluid samples were taken.The well was suspended on 15 August 1980 and the rig was taken to Bergen. The strike was terminated on 14 August and the rig was back on location on August 29. The well was re-entered and operations resumed, now formally as a new well, 30/3-2 R.TestingNo drill stem test was performed. -
