This study, based on extensive fieldwork, interviews and engagement with primary and secondary sources, is the first on the subject to take on the regional, as opposed to the country-specific, dimension. It has four key aims. The first is to bring out the extent to which oil has forged the interaction of the region with the world economy and how the ongoing expansion of the oil sector will deepen this pivotal role. Secondly, how this international relevance of petroleum has shaped postcolonial domestic politics and institutions. Thirdly, it examines the interests of different sets of empowered actors in the partnership between importers, producers and oil companies, their interplay, and the manner and contexts in which their goals diverge or converge. Finally, it analyses the sources of long-term sustainability of the political economy of oil in the Gulf of Guinea amidst seemingly unmanageable chaos.
