Continually updated, last entry January 2011

The East African margin was a neglected exploration blackwater and was perceived to be a gas prone margin, until the recent discovery of oil and gas in the Ironclad-1 and Windjammer wells in the Cretaceous turbidite deposits.

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 ArcView 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. Click here for list >
  
  
• Other information such as earthquake and present day stress tensors, heatflow data, location of major faults and fracture zones, and seep data.
  
  
• Full litho-stratigraphic correlation long the entire margin.
  
  
• Uniform compilation of hyperlinked published seismic cross-sections (93) and
  well data (80).
  
  
• Bibliography currently with over 300 references (correct as of January 2011).
