Irish Sea
Dalkey Island exploration prospect

Previous exploration drilling in the Kish Bank Basin has confirmed the potential for petroleum generation with oil shows seen in a number of wells together with natural hydrocarbon seeps recorded from airborne surveys. New analysis of vintage 2-D seismic data has revealed the presence of a large undrilled structural closure at Lower Triassic level situated about 10 kilometres (6 mi) offshore Dublin. This feature, known as the Dalkey Island exploration prospect, may be prospective for oil, as there are prolific oil productive Lower Triassic reservoirs nearby in the eastern Irish Sea offshore Liverpool. Whilst the Dalkey Island exploration prospect could contain about 870 million barrels (140,000,000 m) of oil in place, this undrilled prospect still has significant risk and the partners are currently advancing a focused work programme in order to better understand and hopefully mitigate these risks. However, given its location in shallow water and close proximity to shore, the prospect is of great interest as exploration drilling, together with any future development costs, are likely to be low.
