Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 7220/11-4 was drilled to appraise the Alta discovery on the southern Loppa High in the Barents Sea. The primary objective was to delineate the eastern extent of the Alta discovery and prove the presence of hydrocarbon columns and fluid contacts similar to those established in the discovery well.
Operations and results
Appraisal well 7220/11-4 was spudded with the semi-submersible installation Leiv Eiriksson on 10 May 2017 and drilled to TD at 2282 m in the Carboniferous Ugle Formation. Operations proceeded without significant problems. The well was drilled with seawater and sweeps down to 471 m, with KCl/Polymer/GEM mud from 471 to 648 m and with Performadril mud with 3.0 – 3.6% glycol from 648 m to TD.
The top of the reservoir was encountered at 1903 m. The well encountered a gross hydrocarbon column of 46.3 m, comprising 1.6 m of gas and 44.7 m of oil in a sequence of Permian-Triassic clastic carbonate sediments, conglomerates and breccias. The gas-oil contact (GOC) was found at 1904.6 m and the free-water level (FWL) at 1949.3 m. The pressure data confirmed similar fluid contacts and gradients to those observed in the previous wells drilled on the Alta discovery, suggesting good communication across the large Alta structure.
Above the oil-bearing reservoir there were oil shows in the Snadd Formation at 620 m, 86

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.
