Shell UK Ltd. spudded Selene exploration well 48/8b-3 in the P2437 license area, UK Southern North Sea, said Deltic Energy PLC in a July 30 release.
In February, Shell signed a drilling rig contract with Valaris to advance drilling of the Selene exploration well and the Pensacola appraisal well (OGJ Online, Feb. 5, 2024). Drilling of the well is expected to take about 90 days.
The Selene gas prospect is considered one of the largest unappraised structures in the Leman Sandstone fairway of Southern Gas basin. Selene joint venture partners estimate the prospect to contain gross P50 prospective resources of 318 bcf of gas (with a P90 to P10 range of 132-581 bcf) with a 70% geological chance of success.
Shell UK is operator at Selene (50%) with Deltic holding the remaining 50%.
