Chrysaor drills dry hole south of Sleipner field
Chrysaor Norge AS drilled a dry hole in the North Sea south of Sleipner field. It is the second dry well drilled by the operator in PL973 following well 15/12-25 (OGJ Online, Mar. 23, 2021). Data acquisition was carried out. The well will be plugged.
The latest well, 15/12-26, the second in PL 973, was drilled by the COSL Innovator drilling rig to a vertical depth of 2,762 m subsea 26 km south of the Sleipner Ost installation and 9 km south of the Grevling discovery. It was terminated in rocks from the Early Permian age in the Zechstein group about 240 km west of Stavanger. Water depth at the site is 86 m.
The objective was to prove petroleum in Late Jurassic (Ula formation) and potentially underlying Late Triassic reservoir rocks (Skagerrak formation).
The well encountered a sandstone layer of about 60 m in Ula, with good to very good reservoir quality. The Skagerrak formation was not encountered.
The rig is now headed for Coast Center Base (CCB Ågotnes) west of Bergen for a temporary stay at the shipyard.
Chrysaor Norge is operator at PL973 (50%) with partners OKEA ASA (30%) and Petoro AS (20%).
