en.Wedoany.com Reported - Equinor and its partners have drilled a dry well in the Heidrun Cellar SE prospect beneath the Heidrun field in the Norwegian Sea. The wildcat well 6507/8-D-4 CH is located in production license 124, 240 kilometers west of Sandnessjøen, and was drilled by the Transocean Encourage rig. The license was awarded in the 10th licensing round in 1986, and this is the tenth wildcat well within the license.
The well targeted deeper formations beneath Heidrun, specifically the Early Jurassic Åre Formation and the Late Triassic Grey Beds reservoir rocks. A total sandstone interval of approximately 161 meters was encountered, with reservoir quality ranging from good to excellent, but no formation tests were conducted. Data was acquired before the well was terminated in the Grey Beds. Well 6507/8-D-4 CH reached a vertical depth of 2,910 meters below sea level in a water depth of 357 meters, and has been permanently plugged and abandoned. Holders of production license 124 include operator Equinor, ConocoPhillips, Petoro, and Vår Energi.
The well is located in the central Norwegian Sea, approximately 240 kilometers from the coast. The Heidrun field is one of the earlier developed oil and gas fields in the Norwegian Sea, characterized by complex faulting and reservoir heterogeneity in the area. The drilling aimed to explore the hydrocarbon potential of deeper sequences beneath the main Heidrun field. Although sandstone intervals with good reservoir properties were encountered, no commercially viable hydrocarbon shows were found. After completion, the operator performed permanent plugging and abandonment operations in accordance with Norwegian Petroleum Safety Authority regulations. This result may have some impact on subsequent exploration plans within the license block, and the operator may reassess the exploration strategy for this prospect or adjust related well location designs.
