Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 6607/12-4 A is a geological side-track to well 6607/12-4, which tested the Alve North-East prospect on the Revfallet Fault Complex in the Norwegian Sea. Well 6607/12-4 found gas in the Middle Jurassic Fangst Group and oil in Turonian age sandstones in the Lange Formation. The objective of the 6607/12-4 A side-track was to prove additional volumes in the Lange Formation and investigate the possible connection to 6607/12-2 S Alve N.
Operations and results
Appraisal well 6607/12-4 A was kicked off from 2289 m in 6607/12-4 on 14 October 20202. It was drilled with the semi-submersible installation Deepsea Nordkapp to TD at 3350 m (3142 m TVD) m in the Late Cretaceous section (Turonian age) of the Lange Formation. Operations proceeded without significant problems. The well was drilled with BaraECD oil-based mud from kick-off to TD.
In 6607/12-4 A the Lange sands were penetrated from 3179 to 3280.3 m (3015.4 to 3090.2 m TVD). The same oil-bearing Lange sands as in 6607/12-4 were encountered, with 'oil-down-to' recorded in all four zones in both wells. Pressure points indicate communication with one of the Lange sands in well 6607/12-2 S Alve N. The only shows observed above OBM in well 6607/12-4 A was on the core in the oil-bearing Lange sands.
One core was cut from 3227.2 m to 3263.2 m across the Lange sands. Wire line RDT fluid samples were taken at 3240.3 m (oil) and 3245.4 m (oil) in the Lange sands.
The well was permanently abandoned on 13 October 2020 as an oil appraisal well.

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.
