Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Well 6406/6-6 A is a geological side-track to well 6406/6-6 S, which found gas in Fangst Group sandstones. The well was drilled to appraise the Jasper prospect on the Halten Terrace in the Norwegian Sea. The primary objective was to confirm a hydrocarbon column in the Ile Formation up-dip from the mainbore.

Operations and results

Wildcat well 6406/6-6 A kicked off at 4215 m in wellbore 6406/6-6 S on 17 November 2018. It was drilled with the semi-submersible installation Scarabeo 8 to TD at 4869 m (4692 m TVD) in the Early Jurassic Ror Formation. The drill string got stuck at TD. Ten days were spent on pipe recovery operations. The string was finally freed by severing a NC50 connection above the dart sub, leaving 291 m of bottom hole assembly in hole. No data (except GR and Neutron/density on LWD) could be acquired. The well was drilled with oil-based mud from kick-off to TD.

Top Garn Formation was encountered at 4510 m (4428 m TVD), top Not Formation at 4632 m (4523 m TVD), and top Ile Formation at 4682 m (4558 m TVD). From the LWD logs good reservoir was confirmed in the side-track, but hydrocarbon saturation could not be confirmed due to stuck pipe.

No cores were cut. No fluid sample was taken.

The well was permanently abandoned on 5 January 2019.

Testing

No drill stem test was performed.

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.
