This text provides a short overview of three further papers published on the theme ‘tectonics and petroleum systems of East Africa’, following the four previous papers published in the February 2018 issue of PetroleumGeoscience. Part I of this thematic set concentrated on the regional tectonics of the region, while Part II includes more basin and regional specific papers on offshore Somalia (Davidson et al.), offshore Tanzania (Sansom) and offshore Mozambique (Butt & Gould). Further papers on the region are still being processed and all will be eventually combined into an online thematic set. The three papers published here span in turn the spectrum between a broad regional paper on an exploration frontier, learnings from recent exploration drilling and the expansion of our understanding of known petroleum systems (Fig. 1). Somalia is undoubtedly the least explored and understood country in East Africa. Davidson et al. presents some recent offshore seismic and details many new features, including a large collapsed delta system in offshore south Somalia and an attractive Jurassic carbonate play on the mid-Somalia High. All such features are yet to be drilled.
