Where is the oil in East Africa, and can it match the gas success story in the region?

Besides the giant gas discoveries in the Rovuma Basin, exploration in East Africa has been disappointing to date, especially in terms of commercial oil finds. There are many oil shows and seeps along the coastline and very large paleo-oil fields (e.g. Bemolanga, Tsimiroro in Madagascar and Wingayongo in Tanzania) as the most likely productsof Permotriassic sourced petroleum systems. Whereas there are several potential Jurassic source rocks in the region, the Cretaceous and the Cenozoic sequence is thought to lack regional source rock intervals.

In this talk we challenge this perception using indirect seismic reflection evidence in the deepwater of the broader Mozambique Channel and also some proven source rock analogues from West Africa. If there is a mid-Cretaceous source rock present in the paleo-deepwater, as the product of distinct worldwide Oceanic Anoxic Events, then there could be some sweet spots for exploration along the margin. For example, the Cretaceous source rocks appear to have reached the oil generation window in parts of the Morondava Basin in Madagascar, due to the prominent sedimentary influx during the Cenozoic.

About the Speaker

Gabor Tari

Dr. Gabor C. Tari holds an MSc degree in Geophysics from Eötvös University of Budapest, Hungary, and a Ph.D. in Geology and Geophysics from Rice University, Houston, Texas. After starting with Amoco on various Romanian onshore exploration projects in 1994, he transferred to the Amoco Angola Team in 1996. After conducting regional basin studies for offshore bid-rounds, he joined the Block 18 project, where several major oil discoveries were made since then. Following the merger between BP and Amoco, Gabor continued to work for the new organization, but eventually joined Vanco Energy Company in 1999. At Vanco, as Chief Geophysicist, then as Vice President of Geosciences, he worked on a large number of projects around Africa, for example in Morocco, Senegal, Ivory Coast, Ghana, Equatorial Guinea, Gabon, Namibia, Mozambique and Madagascar. At Vanco, he also identified the Black Sea Basin as a promising and practically unexplored deep water basin in 2004. Since 2007, Gabor is with OMV in Vienna, Austria, working as the Group Chief Geologist on several projects including various European, Mediterranean, Middle Eastern and African basins. Besides working in the oil and gas industry, Gabor is also engaged in academic affairs by teaching seismic interpretation to graduate students, for a number of years at Rice University in Houston, and lately at the University of Vienna in Austria.
