Experience from the exploration for, and development of, deep-water clastic reservoirs offshore NW Europe has provided an important testing ground for new technology and has subsequently been applied globally. In NW Europe, Upper Jurassic, Lower Cretaceous and Paleogene intervals have proven play fairways, all of which retain exploration potential. Ancient, particularly Tertiary, passive margins are identified as the main areas of current global deep-water exploration interest; a review of play characteristics is given. Innovative geophysical data and data analysis play an important role in deep-water clastic reservoir geology. The roles of AVO and seismic inversion are emphasized in the context of direct hydrocarbon indication and reservoir delineation. In areas of modern deep water, when drilling for ancient deep-water clastic targets, the importance of acquiring the right data at the right time is critical to creating robust predictive models.
