Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 25/8-22 S was drilled to appraise the Lower Statfjord and Skagerrak Formation Iving oil discoveries made in well 25/8-19 S. The primary objective was to evaluate the hydrocarbon potential in the Skagerrak Formation. Secondary objectives were to evaluate the hydrocarbon potential in the Early Jurassic Statfjord Group, the Basement, and the Paleocene Heimdal and Balder formations.

Operations and results

Appraisal well 25/8-22 S was spudded with the semi-submersible installation Transocean Barents on 21 June 2021 and drilled to TD at 2622 m (2555 m TVD) m in Basement rock. The well is vertical down to 1300 m, building to a ca 20 sail angle from ca 1700 m to TD. Operations proceeded without significant problems. The well was drilled with seawater and hi-vis pills down to 1040 m and with Innovert oil-based mud from 1040 m to TD.

The well encountered a 20-metre gas column over a 31-metre oil column in sandstones of moderate to good reservoir quality in the Skagerrak Formation. Pressure data suggests communication in the Skagerrak reservoir between all wells in the discovery. The reservoir quality in the lowermost part of the Skagerrak Formation was not sufficient to confirm mobile petroleum. Gas-Oil contact was established in Skagerrak Formation at 2478.5 m (2427.7 m TVD). The oil/water contact was not encountered.

A 2-metre oil column was encountered in sandstone of good to very good reservoir quality in the lower part of the Statfjord Group, and this has been interpreted to be a separate accumulation to 25/8-19 S (Iving). The oil/water contact was encountered at 2261.7 m (2225.5 m TVD). Well 25/8-22 S also encountered oil in thin sandstones in the upper part of the Statfjor

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.
