Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 24/9-11 S was drilled in the Volund sub-Basin of the North Sea, west of the Volund oil field and close to the UK border. The primary objective was to test the hydrocarbon potential of the injected Hermod sands in the West Volund Prospect. The reservoir is Paleocene reservoir rocks in the Hermod Formation, which is remobilized and injected into the overlying Balder Formation. A sidetrack would be drilled to obtain cores, wireline data and fluid sampling if a discovery was made.
Operations and results
Wildcat well 24/9-11 S was spudded with the semi-submersible installation Transocean Arctic on 1 June 2017 and drilled to TD at 2211 m (2139 m TVD) in the Paleocene Sele Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 206.7 m, with Glydril water-based mud from 206.7 m to 1336 m, and with EMS-4600 oil-based mud from 1336 m to TD.
The primary target injectite sand was encountered within prognosis at 2088 m (2036.9 m TVD). It is a 7 m thick sandstone of Paleocene age with excellent reservoir properties, and with a few thin sands above this main injectite. There were no oil shows above the OBM in the well, but petrophysical analyses indicated residual hydrocarbons in the injectite reservoir sand.
No cores were cut, and

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.
