Petroleum Geology: From Mature Basins to New Frontiers – Proceedings of the 7th Petroleum Geology Conference
‘The Proceedings of the 7th Petroleum Geology Conference is the seventh in a series that has become a tradition known as the ‘Barbican’ conferences. They started life over 35 years ago, in 1974, with a focus solely on North-West Europe, and have a reputation, both from the conferences and the accompanying Proceedings volumes, of being at the forefront of petroleum geoscience; the standard reference for successive generations of petroleum geoscientists.
North-West Europe has matured as a petroleum province and, at the same time, the conference series has matured to be a truly global event.
These Proceedings embrace many of the world’s petroleum provinces in a two-volume set. There are sections on Europe, which still provides the heart of the Proceedings; Russia, the former Soviet Union and Circum-Artic; North Africa and the Middle East; Passive Margins; and Unconventional Hydrocarbon Resources.
In addition, the three Geocontroversies debates, highly acclaimed at the conference, are included, as is a summary of the Core Workshop. A DVD complements the books and, in addition to providing electronic versions of all the papers also includes selected posters and video clips from the Virtual Field Trip session; the latter being a major success at the conference. The Proceedings volumes of this seventh conference are therefore a ‘must’ for every petroleum geoscientist’s bookshelf.

Abstract
Deepwater sedimentary basins are attracting increased attention from the hydrocarbon industry and academia as they remain one of the last geological frontiers still to be fully explored and understood. As part of a regional project to understand basin development offshore Ireland, we have developed and tested new ways of improving seismic images, and of incorporating these improvements into geological interpretations. Here we illustrate this methodology using three case histories from the Porcupine, Slyne and Erris Basins. In each case, the first stage of the workflow consists of reprocessing a selection of key seismic data. Processing includes relative amplitude preservation and advanced demultiple and interpretation-driven pre-stack depth imaging. Interpretation of the data is assisted by incorporating products such as multiple models, pre-stack gathers, velocity models and attributes. Finally, we show how a velocity model can be inverted to exhumation estimates. The results and approach developed here can be applied to other deepwater exploration areas.
