Brønnhistorie
GeneralWell 2/9-6 S was drilled to test the Eidsvoll prospect on the Piggvar Terrace in the southern North Sea. The primary objective was to test the hydrocarbon potential in Late Jurassic sandstones.Operations and resultsA 9 7/8" pilot hole was drilled to 1010 m. No shallow gas or water flow was observed. Wildcat well 2/9-6 S was spudded with the jack-up installation Maersk Integrator on 8 January 2021 and drilled to TD at 4330 m (4305 m TVD) in the Late Jurassic Farsund Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 1010 m, and with RheGuard Prime oil-based mud from 1010 m to TD.The Tyne Group was encountered at 3890 m (3865.8 m TVD) with the target Eidsvoll sandstone unit (Mandal fm)on top down to 4143 m (4118.8 m TVD). The unit is dated Volgian to late Ryazanian. Approximately 121 metres of this was reservoir rocks with poor to moderate reservoir properties. Oil shows in the form of direct and cut fluorescence were recorded in this unit from 3896 to 4283 m. Traces of petroleum were registered in the upper part of the unit where some live hydrocarbons were recorded by MDT fluid scanning. Hydrocarbon odour was noted on the cores and HCS core scanning indicated a light to medium oil mostly migrated, but also generated locally from in-situ shales. Else, no oil shows were seen in the well.Two cores were cut in succession from 3940.2 to 4012.8 m with 100% recovery. MDT fluid scanning was undertaken at 3912.61 m (mud filtrate and live hydrocarbons) and a water sample was taken at 3990.48 m.The well was permanently abandoned on 15 February 2021 as a dry well with shows.TestingNo drill stem test was performed. -
