Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 35/11-17 was drilled to test the Fram West prospect on the Lomre Terrace in the northern North Sea. The primary objective was to test the hydrocarbon potential in the Middle Jurassic Brent Group. Secondary objective was to test the hydrocarbon potential in Middle Jurassic Fensfjord Formation. The Late Jurassic Sognefjord Formation was also expected to be present, but not considered as a significant target.
Operations and results
Wildcat well 35/11-17 was spudded with the semi-submersible installation Songa Trym on 24 March 2014 and drilled to TD at 2889 m in the Cook Formation. No significant problem was encountered in the operations. The well was drilled with Seawater down to 622 m, with KCl/Polymer/Glycol mud from 622 m to 1190 m, with XP-07 oil based mud from 1190 m to 2052 m, and with KCl/polymer/glycol mud from 2052 m to TD.
In well 35/11-17, hydrocarbons were encountered both in the overburden and in the reservoir. The first hydrocarbon were seen at 1590 to1602 m within the Lista Formation. There was a small increase in gas, increased resistivity, and poor oil shows masked by the oil based mud. Further down in the Shetland there were also two thin sand layers from 2025-2027 m MD with poor oil shows. In the Late Jurassic Sognefjord Formation three 4-7 meter thick calcite cemented sandstones with possible hydrocarbons were found.
In the target reservoir sections, hydrocarbons were found at four levels. Gas in a gas down-to situation was found in the Fensfjord Formation from 2352.6 to 2363 m. The Fensfjord Formation also proved oil from 2374 m to an OWC at 2390 m. The Fensfjord reservoir seems to be depleted, and the pressure in the Fensfjord gas is higher than in the oi

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.
