Drilling Activity Summary

Description

MOL, operator of production license PL 820 S in the Norwegian North Sea, completed two Balder Field appraisal wells #25/8-21 S and #25/8-22 S on the #25/8-19 S (Iving) oil and gas discovery. The Iving discovery was proven in 2019 in reservoir rocks from the Palaeocene (Heimdal), the Early Jurassic (Statfjord Group) and the Late Triassic (Skagerrak) and in basement rock. Before appraisal wells 25/8-21 S and 25/8-22 S were drilled, the operator’s resource estimate for the discovery was between 2 and 11 MMcm of recoverable oil equivalent in the Skagerrak formation. The primary target for #25/8-21 S was to find the oil/water contact in Skagerrak sandstones. The secondary exploration target was to evaluate the petroleum potential in the basement rock reservoir. It encountered a 3-m gas column over an approximate 30-m oil column in sandstones of poor to good reservoir quality in Skagerrak. The well was drilled to 2,663 m and the true vertical depth is 2,587 m. Oil was also found in a 6-m sandstone layer with moderate reservoir quality in the lower part of Skagerrak and no oil/water contact was encountered. A separate oil column of about 50 m was found in basement rock with poor reservoir quality with no oil/water contact. The primary exploration target for #25/8-22 S was to evaluate the petroleum potential in sandstones in the lower part of the Statfjord Group and in Skagerrak and the secondary exploration target was to evaluate the petroleum potential in Heimdal and basement rock. The venture hit a 20-m gas column over a 29-m oil column in sandstones of moderate to good reservoir quality in Skagerrak. Pressure data indicates communication in the Skagerrak reservoir between all wells in the discovery. The reservoir quality in the lowermost part of Skagerrak was not sufficient to confirm mobile petroleum and no oil/water contact was encountered. A 2-m 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 in relation to #25/8-19 S (Iving). Water depth at the site is 127 m. The wells have been plugged and abandoned.
