Discover new exploration opportunities on the Northwest African Margin

The Northwest Africa Margin SEEBASE® Study and GIS provides the first continuous 3D depth-to-basement interpretation from offshore Morocco to the Guinea Plateau providing exploration geologists with the essential inputs for play based exploration. 

Included in the study and ArcGIS package is a detailed interpretation of basement geology, tectonic reconstructions, basement depth and architecture, and basement-derived heat flow, to provide the necessary geological context for petroleum systems observations. It is the integration of these geological elements that improves prediction of petroleum systems play elements.

Available for non-exclusive license and ready for immediate digital delivery in a project ready format.

A NEW TECTONIC EVOLUTION

The Northwest Africa Margin SEEBASE Study and GIS includes a new tectonic evolution model for the Central Atlantic, where both rifting and breakup were diachronous along the Northwest Africa Margin.

  • The syn-rift phase can be categorised into four events, providing a high-resolution and terranes-focused solution to refine understanding of diachronous rifting.
  • The pervasive Hercynian basement fabric was reactivated during Central Atlantic rifting, and influenced the geometry of Mesozoic basin development. Basement trends are reflected in the orientation of the trends of Cretaceous exploration targets within post-rift passive margin sequences.
  •  A zone of hyperextended continental crust has been identified below recent hydrocarbon discoveries in in deepwater zones of Mauritania and Senegal. 
  • The SEEBASE can be used to predict the continuation of trends of exploration targets. Many of the geological features highlighted in the SEEBASE present new opportunities for exploration, such as basement highs mapped on transitional crust in the distal continental domain.
