Paper Summary
In frontier basins, number of geological and geophysical assumptions or uncertainties is higher than in well-established oil and gas provinces. In return, standard processing flows on aggressive industry timelines, even with the latest technology, can lead to subpar results in new projects. Assumptions like amount or type of salt, depth and extent of volcanics and velocity-lithology relations along Brasil passive margin are common when high-grading basin with dense 2D or 3D data. Partial reprocessing or uplift processing, taking more time compared to cost-effective timelines, can lead to significant improvements in imaging, even on relatively new or recently acquired data. Both case studies presented, Campos and Potiguar Basin, show that data-driven methods such as DM FWI aided with interpretation can provide high resolution models and improved imaging.
