Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6705/7-1 was drilled in deep water in the northern part of the Fenris Graben in the Norwegian Sea. The well location is approximately 80 km to the northwest of the Aasta Hansteen field. The objective was to test Late Cretaceous sands prognosed to belong to the Nise Formation, which are the main reservoirs in the Aasta Hansteen discoveries.
Operations and results
A 9 7/8" pilot hole was drilled to 2372 m, through the ooze and into formations with sufficient fracture gradient to support setting of the 13 3/8" casing shoe. No shallow gas or shallow water flow indications were observed while drilling the pilot. After this, the rig was moved 50 m towards north-east where a Conductor Anchor Can was pre-laid to stabilize the conductor while drilling the exploration well.
Wildcat well 6705/7-1 was spudded with the semi-submersible installation Transocean Spitsbergen on 6 April 2017 and drilled to TD at 3290 m in the Late Cretaceous (Late Turonian – Early Coniacian) Lysing Formation. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis sweeps down to 2323 m and with KCL/NaCl/GEM/Polymer water-based mud from 2323 m to TD.
Post-drill biostratigraphy suggested a different lithostratigraphy than prognosed. The actual result from the well is that the well penetrated Nise Formation

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.
