Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 24/9-15 S was drilled to test the Froskelår North East Prospect in the Vana Sub-basin in the North Sea. The primary objective was to evaluate the hydrocarbon potential in Intra-Hordaland Group injectite sands.

Operations and results

Wildcat well 24/9-15 S 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 S was kicked off below the 13⅜" casing shoe at 1818 m in 24/9-M-4 Y1H on 29 March 2019. It was drilled with the semi-submersible installation Scarabeo 8 to TD at 4310 m (1900 m TVD) m in the Hordaland Group. Drilling problems required the well to be plugged back. A technical side-track, 24/9-15 ST2, was kicked off from 1838 m and successfully drilled to planned TD at 4310 m (1900m TVD). The well was drilled deviated with inclination between 50° and 84°. It was drilled with Innovert oil-based mud from kick-off to TD.

A total oil column of 49 m TVD was observed in 24/9-15 S and ST2, in an injectite sand complex with top at 3900 m (1821 m TVD). Average porosity was 32% with an 18% net/gross in the pay zone. A sharp oil-water contact (OWC) was seen on the logs at 4077 m (1870 m TVD) in the uppermost part of a massive sand. Pressure data indicated the contact could be up to 7 m TVD deeper. There were no shows above OBM throughout the well.

No cores were cut. No fluid sa

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.
