Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
The 2/8‐18 S well was drilled on the Clapton Prospect in the Feda Graben in the Norwegian North Sea. The main target was chalks of the Shetland Group, analogous to the nearby fields Eldfisk, Eldfisk East, Valhall and Ekofisk.
Operations and results
Wildcat well 2/8-18 S was spudded with the jack-up installation Mærsk Guardian on 23 May 2012 and drilled to TD at 2852 m ((2662 m TVD) in the Late Cretaceous Hidra Formation. It was drilled deviated to avoid shallow gas over the crest of the structure and to penetrate the steeply dipping reservoir at the right angle. The well was vertical down to 1506 m and built up to a sailing angle of ca 36 deg at 1900 m. The well was drilled with KCL/GEM mud down to 568 m and with oil based XP-07 mud from 568 m to TD.
Oil shows were encountered in the Utsira Formation at 870 m (869 m TVD), triggering a wire line acquisition programme to evaluate this reservoir. Pressure samples were acquired, proving a tight reservoir. Fluid sampling was not attempted. Petrophysical analysis concluded a low permeability siltstone reservoir with low oil saturation. Formation tops came in as prognosed down to top Rogaland Group. In the Rogaland Group, the Lista Formation turned out to be significantly thinner than expected, and the Våle Formation was not present. The deviation is interpreted to be caused by a fault, offsetting the lower part of the Lista Formation and the Våle Formation. The main target in the Shetland Group / Ekofisk Formation was encountered at 2742 m (2567.8 m TVD) with oil shows. Coring was initiated, and two cores containing a total of 36 m of core was recovered. All the formations of the Shetla

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.
