Wellbore history
General
Re-entry well 7220/11-3 AR was drilled to appraise the Alta Discovery on the southern part of the Loppa High in the Barents Sea. The objectives were to deepen the 7220/11-3 A well bore to Permian and Carboniferous strata, to evaluate the reservoir properties of Permian and Carboniferous carbonates (Ørn and Falk Formations), and to test the productivity of the Permo-Triassic Alta reservoir by a drill stem test.
Operations and results
Appraisal well 7220/11-3 A was re-entered with the semi-submersible installation Leiv Eiriksson on 27 June 2016. The extension was drilled as a 6-inch hole from 2130 m to a total depth of 2600 m (2414 m TVD) in the Carboniferous Ugle Formation. When drilling at 2246 m in fractured carbonates mud losses occurred. This caused 74 hrs NPT. During P&A the drill string parted when cutting and retrieving wellhead. This caused 43.5 hrs NPT. The well was drilled with KCl/Polymer/GEM mud from 2130 to TD.
The re-entry was drilled entirely within the water zone below the Alta reservoir. MDT pore pressure measurements confirmed the expected Permian water pressures and gradient previously seen in the 7220/11-1 discovery. The pressure points further confirmed a Free Water Level of 1924 m TVD MSL as found in well 7220/11-3 A. Traces of residual oil were observed in the dolomites and limestones from below the FWL (2089 m MD RKB for Leiv Eiriksson), down to approximately 2205 m.
Nine conventional cores were cut in four different coring runs in the interval 2133 to 2298.6 m. In total, 24.9 m was recovered. MDT fluid samples were acquired from two sampl

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
