The East African margin was perceived as an exploration backwater until the
discovery of over 100 tcf of gas in the last two years. This gas may have been derived form
an overmature source rock and oil is predicted in the less deeply-buried parts of the margin.

Our new digital atlas of the East African Indian Margin aims to bring explorationists up to date, and review the geology and hydrocarbon potential of the margin. The ArcMap Geographical Information System maps cover the area from South Africa to the Horn of Africa.
Gross Depositional Environment and Play Fairway maps summarise existing knowledge of the source and reservoir potential.
The study comprises:
- Digitised geological and geophysical maps of the East African Margin from South African to Somalia.
- Systematic chrono-stratigraphic charts along the entire margin.
- Full gravity and magnetic grids – Magnetic, Free Air, Bouguer and Residual Gravity anomalies.
- 13 maps of Gross Depositional Environment – Triassic to Miocene.
- Comprehensive Basin dossier for all 13 basins.
- Other information such as earthquake and present day stress tensors, heatflow data, location of major faults and fracture zones, and seep data.
- Uniform compilation of hyperlinked published seismic cross-sections (419) and well data (193).
- Bibliography currently with over 725 references (Q4 2014).
