Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6407/1-7 was drilled to test the Solberg prospect in the southern part of the Grinda Graben in the Norwegian Sea. The Solberg prospect was seen as a possible continuation of the 6407/1-6 S Rodrigues Lange discovery to the East. The main objective of the 6407/1-7 Solberg well was to appraise and evaluate the continuation and reservoir properties of the hydrocarbon-filled Intra Lange Sandstones, as penetrated by 6407/1-6 S Rodriguez well, which is located ca 5 km to the west.
Operations and results
Well 6407/1-7 was spudded with the semi-submersible installation Borgland Dolphin on 1 February 2014 and drilled to TD at 3376 m in the Early Cretaceous Lange Formation. No significant problem was encountered in the operations. The well was drilled with seawater and sweeps down to 510 m, with Aquadrill mud from 510 m to 1689 m, with Carbosea oil based mud from 1689 m to 2922 m, and with Aquadrill mud from 2922 m to TD.
Well 6407/1-7 discovered gas-condensate in Lange Formation sandstones at 3221 to 3239 m. The reservoir had an average porosity of 16 % using a cut-off of 8%. The gross thickness is 18 m with a net thickness of 12 m and average water saturation of 21%. The gas-water contact is not penetrated by the well.
One core was cut in the interval 3226 to 3236 m with 85% recovery. RCX fluid samples were taken at 3225.1 m (gas/condensate) and 3230.3 m (gas/condensate).
The well was plugged back for sidetracking on 22 March 2014. It is classified as a gas/condensate discovery.

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.
