Investigation reveals billions of barrels in previously discarded basins, highlighting advances in seismic acquisition.
As the energy exploration landscape evolves, so too does the thinking around the basins being investigated. Advancing seismic acquisition and processing technologies in the last decade have allowed for explorers to take a fresh look on frontier and previously discarded basins, with the shifts in thinking and interpretation yielding billions of barrels of results. In this world tour, four deep-water basins are investigated, including the Papuan Basin of Papua New Guinea (PNG), the Scotian Basin of Canada, the Namibian-South African Orange Basin and its Brazilian conjugate margin in the Pelotas Basin. Seismic in the last ten years over each of these areas have allowed for updated thinking in crustal architecture, reservoir fairway modelling, and the identification of source rocks using angle stacks, made possible from long-offset acquisition and high-end processing workflows.
