Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 2/11-3 is located 2.5 km due east from 2/11-2 and 6.5 km south-southeast from the Valhall well 2/11-1. The primary objective of well 2/11-3 was the Late Cretaceous chalk section on the western flank of the East Lobe of the Hod structure. The West Lobe was found to be oil bearing by 2/11-2 in 1974. Seismic indicated an expansion of the chalk section compared to 2/11-2 and that the graben feature found on Valhall extended south-eastward over the East Hod and therefore the possibility for the high reservoir quality Maestrichtian rock to be present in this area.
Operations and results
Well 2/11-3 was spudded with the jacket 4 legs installation Dyvi Beta on 10 October 1977 and drilled to TD at 3052 m in the Early Cretaceous Rødby Formation. The well was drilled in a total of 47 days without any major drilling problems. However, 3 days were spent waiting for the correct Cameron BOP Adaptor Spool.
Well 2/11-3 proved the Hod complex to consist of two individual structures. A domal West Hod structure has a seismically defined closure area of 7.5 square km. East Hod, where 2/11-3 was located, is a northwest-southeast trending anticline covering approximately 6 square km.
The well penetrated a normal sequence of Quarternary-Tertiary section from the surface to the top of the Late Cretaceous at 2774.5 m. This interval typically consists of predominantly clay and shale with thin stringers of limestone and dolomite scattered throughout. The basal Tertiary unit is marked by the occurrence of the Paleocene Ash marker that displays the characteristic metallic blue grey-violet colour of the volcanic tuff. This correlative unit was encountered at 2714.5 m and is 18 meters thick. The cha

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.
