EquatorSPAN is a 2D seismic program set in the equatorial Atlantic margin offshore northern Gabon. The program is comprised of approximately 2,700 km of new data and uncovers the tectonic architecture of the West African Gulf of Guinea margin.

Program Objectives

  • Understand the crustal architecture of West Africa's Atlantic margin to evaluate the hydrocarbon potential of the region
  • Improve understanding of basin formation in the region
  • Map the lateral extent of salt, transform faults and the mini-basins along their boundaries
  • Solve issues related to hydrocarbon expulsion and timing and the thickness of cretaceous units

Key Components

  • Data reveals the rift architecture and very good potential in the mini basins of the north
  • Widespread presence of key hydrocarbon indicators in the data revealing high potential for deeper discoveries
  • Image basement structure, and reveal syn-rift grabens

Using data from our BrasilSPAN and west AfricaSPAN programs, ION geophysicists and regional petroleum geologists are correlating the conjugate ties between these two regions. The data reveals striking similarities in the structural framework of the petroleum systems on both sides of the Atlantic Margin. For this reason, the Africa programs are designed to tie with our BrasilSPAN datasets, making the programs a valuable tool to E&P operators in Africa.
