The purpose of this short contribution is to provide an overview of our current state of knowledge of Africa’s petroleum systems as an introduction to the detailed volume accounts that follow. Toward that end we introduce a set of maps on a supplementary CD compiled by Purdy as part of a confidential report provided to industry subscribers some ten years ago. The maps include subsurface as well as surface structural information but, because of their vintage, have not taken account of more recent information. Nonetheless, the regional geological framework apparent on the maps has not changed and, in that sense, the maps are as relevant today as when they were first compiled. Moreover the maps serve as a useful building block on which more recently acquired exploration data can be readily added by others using facilitating computer programs.

Petroleum Geology of Africa: New Themes and Developing Technologies
As frontier exploration in Africa moves into ever-deeper water and new basins, there is an increasing need to mitigate the high costs by reducing risk. One way of doing this is by drawing on knowledge from other areas. The book includes regional papers ranging from syntheses on a continental scale to details of the salt tectonics of the West African margin. It also addresses the need to continue using technologies to their limits by including papers on topics as diverse as gravity interpretation and fluid inclusion studies. The book provides essential reading for those requiring further insight into the origins of Africa’s diverse petroleum systems, and will be key to geologists and geophysicists involved in the exploration for and exploitation of oil and gas throughout Africa. Of particular note is the supplementary CD-ROM containing maps of Africa’s petroleum basins classified by age of target reservoir system.
