The Atlantic Margin play – focused on the coastal basins of eastern South America and western Africa – is drawing increasing strategic focus and attracting exploration and production (E&P) investments.

Recent large-scale discoveries by international oil companies (IOCs) in Guyana and Namibia have ignited exploration activity across frontiers such as São Tomé and Príncipe and Uruguay, as well as producers like Angola and Brazil, making the margin one of the most active areas for E&P globally.
