Petroleum Geology of Ireland provides a comprehensive review of the petroleum geology of Ireland and its very extensive continental shelf. The authors chart the fifty-year history of petroleum exploration in Ireland, from early drilling onshore to the present frontier exploration in the deep water Atlantic basins. The structural framework and regional geological setting of the sedimentary basins is described in two chapters, and this is followed by a review of the history of Irish onshore and offshore exploration, together with an outline of the licensing framework. The onshore basins, largely Carboniferous and older, are then considered as they guided the initial understanding of the younger offshore geological framework. Pre-Permian to Cenozoic stratigraphy of the region is explained in five chapters, each illustrated by palaeogeographic maps that are based both on onshore geology and on the results of offshore drilling. The major regional groups of basins are then considered and for each there is analysis of basin development and petroleum systems, together with a review of their exploration history, plays and prospects. The Celtic Sea basins, south of Ireland, contain a thick Mesozoic succession and host a number of producing petroleum fields and sub-commercial discoveries. The Atlantic margin basins, with thick successions of Mesozoic and Cenozoic sediments, are the largest and least well explored of the Irish basin groups but offer a number of promising oil and gas discoveries and frontier prospects. Finally, the Northern Ireland and Irish Sea basins, onshore or in shallow waters, contain a thick Upper Palaeozoic to early Mesozoic succession which provides important insights into the regional geological evolution and also the challenges of trying to understand the petroleum habitat of Ireland. Future and potential petroleum prospects in the Irish offshore region are reviewed in the final chapter, which also examines briefly the gas storage potential of onshore and offshore reservoirs. The book, which contains comprehensive reference lists with each chapter, will be of value to oil industry geoscientists seeking to understanding Irish onshore and offshore geology and to academic researchers with an interest in marine and petroleum geology.
