Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 24/9-15 A is a geological side-track to 24/9-15 S drilled to test the Froskelår North East Prospect in the Vana Sub-basin in the North Sea. The primary objective of 24/9-15 A was to investigate the existence of two dykes in the

Northern extension of the Frosk injectite complex.

Operations and results

Appraisal well 24/9-15 A was part of a compound well consisting of exploration well bores and development well bores. The compound well was drilled with the mother bore, 24/9-M-4 Y1H, initially drilled to 13⅜" casing point in the Hordaland Group. From this depth the planned exploration wells, 24/9-15 S, ST2 & A, were drilled before operations to drill the Frosk Test Producers recommenced.

Wildcat well 24/9-15 A was kicked off below the 13⅜" casing shoe at 1870 m in 24/9-M-4 Y1H on 19 April 2019. The well started off with 55° inclination at kick-off and drilled horizontal from ca 3200 m. At 3853 m a pressure-drop of 87 bar and loss of circulation occurred, and it was decided to abandon the hole without reaching the second targeted dyke and to preserve the main bore for the Frosk test producer wells. Hence, 3853 m (1843.6 m TVD) in the Hordaland Group shales became TD of the well. The well was drilled with oil-based mud from kick-off top TD.

The eastern dyke (injectite sand) was penetrated from 3151.5 m to 3252.7 m (1841.4 to 1843.3 m TVD). The dyke was oil-bearing, but no hydrocarbon contacts were seen. Fair patchy whitish blue direct fluorescence above the OBM was observed in the dyke sand, else no oil shows were observed in the 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.
