Paper Summary
The theme of value generation from different acquisition technologies in a climate of cost-saving pressure challenges for new marine exploration and 4D seismic acquisition shaped the agenda for the EAGE workshop on Marine Acquisition hosted in Oslo on August 22-24, 2018. This paper reviews the incremental improvements in survey efficiency that have taken place over the last couple of decades, and the step-change improvements that have recently emerged with the industry-wide use of both physical and virtual multi-source configurations.
