Ireland North Celtic Sea exploration basin
The North Celtic Sea Basin lies off the southeast coast of Ireland, extending through Saint George's Channel to Cardigan Bay. The basin is gas-prone, and the main reservoirs are Late Jurassic and Early Cretaceous sandstones. The Early Cretaceous Wealden Formation has proved to be the most attractive exploration target, including the large Kinsale Head gas field discovered in 1971. Although large areas remain unexplored, the basin is considered mature. Only one exploration well (dry hole) has been drilled since 2008 and we do not currently consider exploration in the basin to be a material consideration. The report details the historic exploration performance only. A comprehensive update will be carried out if and when activity necessitates it.
