EquatorSPAN is a seismic program set in the equatorial Atlantic margin offshore northern Gabon. The program is comprised of two phases of acquisition, phase I of 2,723 km and phase II consisting of 2,123 km of new data. Together these phases uncover the tectonic architecture of the West Africa Margin in the Gulf of Guinea. EquatorSPAN also provides a risk-reduction strategy for exploration in the region’s transform fault margin. The latest phase was recorded in 2017 using a 12 km cable and acquisition optimized for our de-ghosting technique.

Both phases tie with our existing West Africa programs, CongoSPAN I and CongoSPAN II to create a regional framework of the West African coast.

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.

  • 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

  • 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
